Question:

Brushless DC motor is AC motor or DC motor, why?

Brushless DC motor is AC motor or DC motor, why?

Answer:

The brushless DC motor and the traditional brush DC motor supply are DC, but only use the reversible drive circuit instead of the brush and commutator. The rotor is a magnetic pole, and the stator is an armature. The actuator turns the current in the stator windings, similar to AC induction motors.AC motor is AC power supply, the speed is related to the power supply frequency, asynchronous and synchronous.
Brushless motor is a direct current motor.Adopt DC work, adjust pulse speed by adjusting pulse width.AC motor works by alternating current and adopts frequency converter to adjust speed.
That is the difference is that the brushless DC motor and AC motor rotor stator are magnetic, is only the armature, rotating magnetic field in the stator of the former is generated by the sensor and a driving circuit, an alternating current generated by the.That doesn't know much, but brushless DC motor has one advantage, that is, it has a linear characteristic of DC motor and a little better.
The DC motor only has no brush and commutator. It should be inside to check the rotor position through the Holzer sensor, make the drive circuit turn over, and make sure the motor turn in one direction
