Who knows the motor of the airplane model? Let's talk about it

The wire resistance of high-speed Madari is low, so the speed is high without brush to reduce the spark of discharge when the motor rotates, and also reduce the reverse force of the motor, that is, the force (electromagnetic effect) of the magnetic field on the wire. Brushless DC motor uses semiconductor switching devices to realize electronic commutation, that is, electronic switching devices are used to replace the traditional contact commutator and brush. Excessive current will damage electronic components.
