Composition Of Permanent Magnet DC Motor

1. From the perspective of the generalized motor concept, a permanent magnet DC motor consists of three major components: a motor body, a position detector, and a direct-passive passive inverter;
2. If there is a one-to-one correspondence with the original DC motor, the rotor formed by the permanent magnet corresponds to the stator of the original DC motor, and its function is to generate a constant air gap magnetic field, and the position detector and the inverter together constitute an electron The commutator replaces the mechanical contact commutation device of the original DC motor;
3. permanent magnet DC motor control system is part of the speed control system.
