    RC Brushless Motor

    Electric Motor Principles:

    • The conversion form of electric motor principle is to take electrical energy into mechanical energy. A free-hanging wire was dipped into a pool of mercury on which a permanent magnet was placed. When a current was passed through the wire, the wire rotated around the magnet, showing that the current gave rise to a close circular magnetic field around the wire. This motor is often demonstrated in school physics classes, but brine(salt water) is sometimes used in place of the toxic mercury. This is the simplest form of a class of devices called homopolar motors
    • Later there is a refinement called "electromagnetic self-rotors". These were demonstration devices only, unsuited to practical applications due to their primitive construction. Started experimenting with devices called "electromagnetic self-rotors". Although they were used only for instructional purposes, the first device was demonstrated to contain the three main components of practical direct currentmotors: the stator, rotor and commutator. The device employed no permanent magnets, as the magnetic fields of both the stationary and revolving components were produced solely by the currents flowing through their windings

    How Does a DC Motor Work?

    DC Motor Basics:

    • DC motors are in countless consumer electronic devices from CD players to computers to radio-controlled airplanes. There are many different kinds of DC motors, but they all work on the same principle. They turn current into pulses of magnetism, which they use to turn a rotor. There are many different kinds of electric m

    Brushed DC Motors:

    • Brushed DC Motors have two coils of wire around a rotor in the middle. Surrounding the coil are two magnets, both facing in the same direction. When the coils are facing the magnets, electricity flows into them. When electricity flows into a coil, it creates a magnetic field, and this magnetic field pushes the coils away from their magnets. As the rotor turns, the current shuts off. When the rotor has turned 180 degrees, each rotor faces the opposite magnet. The coils turn on again, this time with the electricity flowing in the opposite direction. This creates another pulse, pushing the rotor around again. The rotor has electric contacts on it, and there are small metal brushes that bump against the contacts. The brushes send in electricity, turning the motor on and off at the right times

    Brushless DC Motors:

    • Brushed motors work reasonably well, but they have a few drawbacks. The brushes create friction, slowing the motor and wasting energy. They also wear out. The brushes corrode or get worn away by friction from the rotor. Brushless motors solve both of these problems. A brushless motor has a permanent magnet on the inside of the rotor, facing so that its north and south poles are perpendicular to the axis of rotation. Around the rotor are coils. The coils work much like they do in a brushed motor. They give out timed pulses to push the magnet, spinning the rotor. Because there are no brushes, however, the motor can't control itself. Instead, it is attached to an electronic speed controller, which gives pulses of electricity at a certain speed to control the motor. The faster the coils pulse, the faster the motor will spin

    Brushless DC motors' Advantages over Conventional Motors:

    • Compared to AC fans using shaded-pole motors, they are very efficient, running much cooler than the equivalent AC motors. This cool operation leads to much-improved life of the fan's bearings
    • Without a commutator to wear out, the life of a DC brushless motor can be significantly longer compared to a DC motor using brushes and a commutator. Commutation also tends to cause a great deal of electrical and RF noise; without a commutator or brushes, a brushless motor may be used in electrically sensitive devices like audio equipment or computers
    • The same Hall effect sensors that provide the commutation can also provide a convenient tachometer signal for closed-loop control (servo-controlled) applications. In fans, the tachometer signal can be used to derive a "fan OK" signal
    • The motor can be easily synchronized to an internal or external clock, leading to precise speed control.
    • Brushless motors have no chance of sparking, unlike brushed motors, making them better suited to environments with volatile chemicals and fuels. Also, sparking generates ozone which can accumulate in poorly ventilated buildings risking harm to occupants' health
    • Brushless motors are usually used in small equipment such as computers and are generally used to get rid of unwanted heat
    • They are also very quiet motors which is an advantage if being used in equipment that is affected by vibrations
    • Modern DC brushless motors range in power from a fraction of a watt to many kilowatts. Larger brushless motors up to about 100 kW rating are used in electric vehicles. They also find significant use in high-performance electric model aircraft

This is a great RC brushless motor only while it is running. It only lasted a few days before it blew out. I think the best thing to do for anyone is to spend the extra money on a brushless motor because it will last much longer and it is faster.

I bought this brushless electric motor in order to replace the original one that I burned out on my Stampede. The brushless electric motor arrived in perfect conditions and in just 3 minutes I was able to race again.

Today I was looking at the RC boat motors you sugested and man the RC brushless motors are what the doctor ordered. Even if I was not an electrician I think I could undersatnd this. <br/>Thanks again.

I agree with everything that guy said about this being able to speed up the helicopter. I'm going to recommend this to everyone and anyone who likes RC helicopters. <br/> <br/>This, combined with the durability material, just saved me thousands of dollars on an expensive speed up machine, not to mention space savings. <br/> <br/>I was leery to buy this since it's so cheap.

Other Thoughts: 
Even though I'm criticizing the durability, I'd still recommend this to anyone who's mastered the RC helicopters and is looking for the next cheap thrill. <br/> <br/>Overall, I found this pretty easy to control and a bus-load of fun. You want to start out in a much larger space than you did with the RC helicopter. As soon as you pitch this forward, it's going to be challenging to get back under control again. A gymnasium or big conference room would be great. The conference room with a table is nice because you can rest your controller on the table and fly it pretty close to the table, risking less if it falls. <br/> <br/>Now, the durability issue is that the top balancing post has this plastic cap that connects it to the rotor shaft which is not strong enough to withstand a hard crash, and it has nothing to protect or cushion it. That pivot point right where it connects to the metal shaft is under a lot of initial torque and then spins at a high velocity, and when your heli yaws and tips too far, it goes down, and that bar strikes the ground pretty hard and can break. I've been able to repair it a bunch of times with super glue, but I wish they'd made it aluminum or even a tiny brass piece and charged the extra 5 bucks. If anyone finds a replacement, let me know!
