How Brushless Motors Work And Why We Need Them

auto9

Motors are the basis of most electronic machines these days. One of the most commonly used motors is the DC engine,which offer high speeds and torque for the machines. It does so by taking the electrical energy from the mains and converting it into mechanical energy. This, in turn, is used for position maintenance and motion control.

The working of the DC motor is based on a strong magnetic field created by an electromagnet. It synchronizes this magnet with the armature wound and offers speed and power to control systems or maintain a position. This motor has two variations, namely brushed and brushless. This article will delve further into the working of the latter. First, let’s learn about the challenges posed by brushed motors, which have been overcome by brushless ones.

Challenges of Brushed Motors

The main problem of these motors is that the brushes usually wear out with time. Since these brushes are constantly making and breaking connections, there is a possibility of sparks and, as a result, short circuits. These may harm the machines. Brushed custom motors are known to limit the speed and not allow the machine to reach its maximum potential. They also limit the number of poles on the armature. Lastly, with the electromagnet in the center, they maymake it difficult to cool the motor quickly.

Working of Brushless Motors

Brushless DC motors (BLDC motors) areessentially brushed motors turned inside out, without the brushes. All you need are permanent magnets on the rotors and electric ones on the stators. Then you can easily connect the motor with a computer using high-powered transistors.

Benefits of BLDC

Since there are no brushes and they work with computer controls, BLDC motors are more accurate. This has earned them the nickname of precision motors. They can adapt to various speeds with the same amount of efficiency. The absence of brushes also means no sparks and no stoppage due to wearing out of brushes. As a result, the motors work longer and faster. Also, since the magnet is placed outside, cooling them naturally or with automated fans is easy.

From electrical vehicles in transport to domestic and commercial HVAC systems, from industrial engineering needs to motion control spaces, these motors are ubiquitous in manufacturing units across the world.

Saltwater Trolling Motors

For decades, fisherman have depended on electric trolling motors for their freshwater fishing and boating needs. Electric trolling motors of today are very quiet that makes our fishing at its best whenever we are on small lakes or creeks because it does not scare the fishes away. This motor is also precise when trying to maneuvering through small places or shallow water areas. The only bad thing about the original electric motors is that they weren’t much good in saltwater because it would cause corrosion. Switches, shafts, housing and mounts were all vulnerable to this. It was only a matter of time before someone would come up with an idea to prevent this from happening.

Then came the Salt Water Trolling Motors. These actually came about saltwater fishing when guides began using them to pursue giant tarpon in the salt-waters of Homosassa, Florida. They started usung urethane potting to completely seal the outside of the motor with a half inch coating of water resistant material since the head of the electric trolling motor would start to corrode as soon as it hit the saltwater.

In the earlier days, getting an electric motor ready for saltwater use was a big chore because of the corrosion problems. Every metal part and electric connection of the trolling motor must be covered with silicone sealant making you to almost completely disassemble the trolling motor. This would work for a year or two, depending on how often you used it.

But today, you don’t have to worry about doing all the hard work just to seal your motor for salt water use. Manufacturers had finally seen the need and demand of saltwater trolling motors and engineered their own models that will withstand saltwater use right out of the box.

So how do you know which motor is best for you? Trolling motors or electric motors use battery power to propel the boat. You will need to figure out how much power you will need to move through the water efficiently. The length and the weight of the boat are the few things to consider. You must anticipate how much gears you carry and the number of persons that will possibly ride your boat. There are charts to help you determine which model and thrust rating is best for you. Electric trolling motors come in 3 different power systems, 12, 24 and 36 volt. The 12 volt is the most inexpensive but could lack the thrust power that you may need.

To satisfy your needs, look for more information before you buy, you check it out online by visiting some trolling motor sites.

How To Buy A Properly Sized Motorcycle Helmet

auto1

Before you start your search for a motorcycle helmet, or take the next step towards buying a helmet, you should be aware of how motorcycle helmets are meant to fit. When buying a helmet, how do you know that it fits correctly? Buying a helmet that offers maximum protection requires you to have an understanding of the proper sizing and fit. For both safety and comfort, it is essential that you wear a proper fitting motorcycle helmet. Many new riders end up buying a helmet that is too large. While this may be comfortable, it may not be tight enough to remain on your head during a crash, and will therefore provide less protection than a properly fitted motorcycle helmet.

Most helmet manufacturers have size charts to assist you in choosing the appropriate size. Most helmets come in small, medium, large, and extra-large. Keep in mind that not all helmets are made the same; sizes often vary between manufacturers. Before buying a helmet, you’ll need to have an idea of your approximate size. Measuring the head is a good starting point for determining your correct motorcycle helmet size. Measure around your head at a point about an inch above the eyebrows, which will result in the largest possible circumference. Hat size can be another rough starting point for determining your motorcycle helmet size.

When buying a helmet, always be sure to try it on, either at the store or when it arrives in the mail. When trying on a full face motorcycle helmet, make sure that the helmet rests just above your browline. Try to fit your thumb between the helmet and your forehead. The helmet should rest so closely against your forehead that there is no room left to fit a finger. Conversely, if you feel like the helmet will leave red marks on your skin or it’s so tight that it is uncomfortable to get onto your head, it may be too small. Make sure that it does not obstruct your field of vision. Shake your head to check that the helmet feels secure, not too loose, on your head. If you wear prescription glasses, make sure that you’ll be able to wear them comfortably with the helmet.

If you are a woman, it is also crucial to understand the differences between men’s and women’s helmets. Although these differences are subtle, and you may even not notice any stylistic differences, buying a helmet that fits you correctly is crucial if you want for maximum protection while riding. If you accidentally end up buying a helmet designed for men, it will not fit as well as a helmet designed for women. In addition to potential design variations, most women’s motorcycle helmets are slightly smaller than the same size in men’s motorcycle helmets.

Cool 250cc Motor Scooters

auto15

You’ve wanted one and now is the time. You need some cheap wheels because you are sick of paying $50 every time you go to the gas station to fill up your car. Well, scooters are a great alternative, especially the 250cc scooter. The great thing about these is that they can pretty much go as fast as a motorcycle, yet they are a lot easier to handle. It takes the intimidation factor away immediately.

Here are some of the most popular 250cc scooters out there:

Honda
Though they are one of the most popular scooter makers, they do not have one in this class. You would have to go with the small SH150i or the much larger 600cc Silver Wing.

Kymco
The GrandVista 250 has a 4 stroke engine and you can expect to pay in the mid $4000 range. The one thing this model does not feature that others do is fuel injection.

Vespa
The GTS 250 is the more affordable version ($6000) and the GVT 250 is the high end model ($7000+) because of its old school looks. Both feature a 4 stroke, liquid cooled engine with electronic fuel injection.

United Motors
At just over $2000, the Expressway 250 comes at the most affordable option in this category. It still has a 4 stroke liquid cooled engine, so if you are on a tight budget make sure you take a long hard look at the Expressway. It has great value and power for the money.

Cheetah
The Cheetah Touring 250 is a very popular model that comes in at around the $3000 mark. Not bad for this size scooter. No fuel injection, but it can still move pretty fast.

Yamaha
Yamaha has a one called the Roketa MC-54-250, not exactly the best name, but a good set of wheels nonetheless. They say it tops out at 85 mph and is priced around $2000.

What else is fun to drive, can go 80 mph, and get 80 mpg? I’ll tell you right now that there is no car that can. So if you are in the market for a new vehicle, take a quick look at the 250cc scooter market. They may give you the affordability and efficiency you are looking for.

Give Your Car Personality Befitting Her Name

auto14

Whether you’ve got a shiny new sports car, a classic cruiser, or a beloved beater, your car has character. You’ve been thinking about enhancements to make her stand out in a crowd. Or in a parking lot. Like a tattoo, bumper stickers and other adornments can either be cool or tacky. Either way, you can’t seem to find one that speaks to your personality and priorities. If you’re looking for something that stands out and makes a statement about you and your vehicle, without being so literal about it, you should think about getting a chrome car badge.

Car badges are graphic representations of things that matter to you, but engraved in shiny metal. They can be tinted gold, blue, or rainbow. The can also, obviously, be that classic chrome. If you have a muscle car, you might want some 3-D flames. If you’re an environmentalist who chose your car from a short list of hybrids, a simple green leaf might do. You can find insignia for your favorite sports team, skulls, flowers, anything your heart desires. Unlike bumper stickers, however, these are raised from the surface of your car and look like they might have been custom from the factory, like a special edition. Best of all, they adhere to your car with a paint-safe adhesive, and the more popular ones usually cost less than $15 online and are shipped straight to you the next day!

So there you have it. You can be cool and stylish without announcing to the world your political views, how many kids you have, or insulting anyone. You don’t even need to pay an extra fee for a cryptic vanity license plate! Turn your car into the Batmobile and your truck into an all-out, mobile tailgate party with a cool chrome car badge.

There Are Many Good Reasons For Buying Used Cars

auto14

Did you know that a new vehicle loses some of its value as soon as it is taken off the lot? That’s right. A new automobile becomes just like all the other used cars out there as soon as you sign on the dotted line. That is one of the many reasons why pre-owned vehicles are a better value. Models with just a thousand or so miles on them sell for a lot less. Plus, dealerships that sell these kinds of automobiles still offer buyers warranties and cash incentives.

Would the idea of a used car appeal to you more if buying one meant you could save money on insurance rates? Well, you can. The more valuable a machine is, the more you will pay for insurance. That’s because newer vehicles cost more to fix than older ones. This makes perfect sense, but some people still want to believe that it is more rewarding to own a new automobile. For one reason or another, they think used cars are only for people that cannot afford anything else. Actually, they are ideal for individuals that want more for their money. Think of all the extra things you can splurge on if you opt to purchase a machine that has just a few thousand miles on it. In most cases, used cars like these are still under the factory warranty as well. Therefore, you can take advantage of the same perk that the new model buyer gets, but you save thousands of dollars that they don’t.

Another reason for buying a pre-owned automobile is that you can trade it in sooner if you ever want to buy a model that runs on electricity or water vapor or some other unique substance. Hybrids and electric vehicles are becoming more and more popular as gas prices continue to rise. It is even starting to seem like they will become more affordable as the auto industry evolves over the coming years. If you buy a used car now, you can choose an eco-friendly model later on when manufacturers start to offer them for cheaper than ever before.

With these new considerations in mind, you are probably eager to find a local dealership that sells certified pre-owned automobiles. If you have the time while you are shopping and comparing prices, visit multiple lots in the area before you make a concrete decision on one certain make and model. The more options you give yourself, the better chance you will have of finding a vehicle that meets all of your needs.

Rc Cars Toys For The Big Boys

auto13

Speed enthusiast? Monster-lover! Then look no further than the universe of RC cars.
Why RChobbies?

RC cars have been around since the 40s, where only the elite had access to the relatively expensive hobby. But the heart-racing sport is not an outdated one. Today RC hobbies have occupied a niche in the commercial market, with RC vehicle sellers owning websites for online shopping.

The fact is RC cars arent just a substitute to real cars. Although most are modeled after life-sized automobiles, there is a difference in how they work. By the name itself, its pretty obvious that you get to do a lot of finger work in driving these m miniature babies. Certainly there is no possibility for a ride, but any enthusiast can vouch for the pride RC hobbies provide. Who wouldnt be happy to own hot rod and a monster truck at the same time?
Also, unlike real thing, an RC vehicle can do back flips and drifting without any real prospect of injury. Because build-your-own (kit-type) and ready-to-race (pre-assembled) cars come with parts and accessories, you dont need a mechanic to repair any damage — just DIY, and youre good to go.

Which RC Car?
Generally RC cars are classified as toy-grade or hobby-grade. Toy-grade cars are just that: pretty cars with nice interior work that are either too heavy or too weak to do anything. The motor isnt for racing, and crashing one damages it for life. These small machines are primarily designed for children. Hobby-grade cars are for the serious RC racers, who need strength, stability, and speed to win competitions such as those sponsored by the International Federation for Model Auto Racing. Online shopping usually is a fast way for purchasing both these types.Those taken with RC hobbies usually choose between an off-road and an on-road car. Either way these cars can be driven by a methanol-castor oil-nitro methane mix in a two-stroke engine, or by an electric motor run by a battery. The power sources of these different types can be bought with online shopping.

The first type, called a nitro RC car, is more popular in that it sounds similar to real cars and even gives off smoke. This car is faster than electric-driven ones, but needs appropriate maintenance to clean unburned fuel. The second type, also called a lipo RC car, should be regularly hooked to an electric outlet to recharge the nickel/lithium-powered battery. It is much cleaner than its nitro counterpart, but needs a cool-down period after a race to avoid overheating.RC cars are available from different manufacturers, either through online shopping or through store outlets. Popular brands include HPI, Associated, Traxxas, and Losi.

How much?
The price of RC cars ranges from $75.00 (A-Tech monster) car to a $1650.00 (Beetle Off-Road 4WD) and above. The cost depends on both the model and the manufacturer, with some makers more expensive than the others.
