Classification of motors
(1) Classification by motor power supply
DC motor and AC motor
DC motors are further divided into winding-excited DC motors and permanent magnet DC motors
AC motors are divided into single-phase motors and three-phase motors.
(2) Classification by structure and working principle
DC motors are further divided into asynchronous motors and synchronous motors
DC motors are further divided into brushless DC motors and brushed DC motors;
Asynchronous motors are divided into induction motors and AC commutator motors; synchronous motors are divided into permanent magnet synchronous motors, reluctance synchronous motors and hysteresis synchronous motors.
(3) Classification by purpose
Electric motors can be divided into drive motors and control motors according to their purpose.
(4) Classification by rotor structure
The structure can be divided into cage induction motors and wound rotor induction motors.
(5) Classification by operating speed
Electric motors can be divided into high-speed, low-speed, constant-speed, and speed-regulating motors according to their operating speed.
