What types of motors are there? What are the characteristics of different motors?

1. According to the type of working power supply, it can be divided into DC motor and AC motor. (1) DC motor: According to the structure and working principle, it can be divided into brushless DC motor and brushed DC motor. It can also be divided into permanent magnet DC motor and electromagnetic DC motor. Permanent magnet DC motors are divided into rare earth, ferrite and Al-Ni-Co permanent magnet DC motors according to materials. Electromagnetic DC motors are divided into series excitation, parallel excitation, separate excitation and compound excitation DC motors according to excitation modes. (2) AC motors can be divided into single-phase motors and three-phase motors.
