2. Classified by Structure and Operating Principle: Can be divided into DC Motors, Induction Motors, and Synchronous Motors.
DC Motor
According to their structure and working principles, they can be classified into: brushless DC motors and brushed DC motors.
It can further be divided into permanent magnet DC motors and electromagnetic DC motors.
Permanent magnet DC motors can be further classified into rare-earth, ferrite, and Alnico permanent magnet DC motors based on their materials.
Electromagnetic DC motors are further classified into series-wound, shunt-wound, separately excited, and compound-wound DC motors based on their excitation methods.
AC motors can be classified into: single-phase motors and three-phase motors.
2. Classified by Structure and Operating Principle:可分为 DC Motors, Induction Motors, and Synchronous Motors.
The rotor speed of an induction motor is always slightly lower than the synchronous speed of the rotating magnetic field.
The rotor speed of a synchronous motor remains constant at the synchronous speed, regardless of the load magnitude.
3. Classified by purpose, there are drive motors and control motors.
4. Classified by operating speed, there are high-speed motors, low-speed motors, constant-speed motors, and variable-speed motors.
Low-speed electric motors are further classified into gear-reduction motors, electromagnetic reduction motors, torque motors, and claw-pole synchronous motors, among others.
