There are many types of motors.
1. Classification by working power supply According to the different working power supplies of motors, they can be divided into DC motors and AC motors. Among them, AC motors are also divided into single-phase motors and three-phase motors.
2. Classification by structure and working principle Motors can be divided into DC motors, asynchronous motors and synchronous motors according to their structure and working principle.
Synchronous motors can also be divided into permanent magnet synchronous motors, reluctance synchronous motors and hysteresis synchronous motors.
Asynchronous motors can be divided into induction motors and AC commutator motors. Induction motors are further divided into three-phase asynchronous motors, single-phase asynchronous motors and shielded asynchronous motors. AC commutator motors are further divided into single-phase series motors, AC/DC dual-purpose motors and repulsion motors.
DC motors can be divided into brushless DC motors and brushed DC motors according to their structure and working principle. Brushed DC motors can be divided into permanent magnet DC motors and electromagnetic DC motors. Electromagnetic DC motors are further divided into series-excited DC motors, shunt-excited DC motors, separately-excited DC motors and compound-excited DC motors. Permanent magnet DC motors are further divided into rare earth permanent magnet DC motors, ferrite permanent magnet DC motors and aluminum nickel cobalt permanent magnet DC motors.
3. Classification by starting and running mode Electric motors can be divided into capacitor starting single-phase asynchronous motors, capacitor running single-phase asynchronous motors, capacitor starting and running single-phase asynchronous motors and split-phase single-phase asynchronous motors according to their starting and running modes.
4. Classification by use Electric motors can be divided into drive motors and control motors according to their use.
