What is an induction motor? How is it different from a regular motor? How much do small induction motors cost? Are there induction DC motors?

Ordinary AC motors are induction motors, which drive the rotor rotation through the rotating magnetic field induction

Commonly referred to as brushless motors are induction DC motors. Brushless DC motors use semiconductor switching devices to realize the electronic commutation, i.e., replacing the traditional contact commutator and brushes with electronic switching devices. In simple terms, relying on changing the alternating frequency and waveform of the current wave input to the stator coil of the brushless motor, around the winding coil to form a magnetic field rotating around the geometric axis of the motor, this magnetic field inductively drive the rotor on the permanent magnet magnets rotate, the motor rotates.

In general, the structure of the brushless motor is relatively simple, the real decision to use its performance or brushless electronic governor, a good electronic governor need to have a microcontroller control program design, circuit design, complex machining process and other processes of the overall control, so the price is much higher than the brush motor.
