Classification Of Permanent Magnet DC Deceleration Motor

Jun 08, 2017

Permanent Magnet DC Deceleration Motor is divided into permanent magnet brushless DC motor and permanent magnet brush DC motor.

Permanent magnet Brushless DC motor is a DC motor with one or more permanent magnets to establish a magnetic field. Its performance is similar to that of a constant excitation current, which can be easily controlled by changing the armature voltage. Compared with the DC motor, it has the advantages of small volume, high efficiency, simple structure and low copper content. It is the main type of low power DC motor.

Permanent magnet brush motor stator is equipped with a fixed main pole and brush, the rotor is equipped with armature windings and commutator. DC power supply through the brush and commutator into the armature winding, resulting in armature current, the armature current generated by the magnetic field interaction with the main magnetic field to produce electromagnetic torque, the motor rotating belt load.

The main difference between them is that the field windings of permanent magnet brushless DC motors are replaced by permanent magnets.

Permanent magnet Brushless DC motor: a DC motor with one or more permanent magnets to establish a magnetic field. Its performance is similar to that of a constant excitation current, which can be easily controlled by changing the armature voltage. Compared with the DC motor, it has the advantages of small volume, high efficiency, simple structure and low copper content. It is the main type of low power DC motor.

Permanent Magnet Brush DC Motor: Brush motor mounted on the stator with a fixed main pole and brush, the rotor is equipped with armature windings and commutator. DC power supply through the brush and commutator into the armature winding, resulting in armature current, the armature current generated by the magnetic field interaction with the main magnetic field to produce electromagnetic torque, the motor rotating belt load. Due to the presence of brushes and commutators, the structure of the brush motor is complex, the reliability is poor, the fault is large, the maintenance workload is large, the life is short, and the spark is easy to produce electromagnetic interference.
