Industrial Motor (English: Electric machinery, commonly known as motor) refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. It is represented by the letter M in the circuit (D in the old standard).
Its main function is to generate driving torque as a power source for electrical appliances or various machinery. Its main function is to convert electrical energy into mechanical energy.
Divided according to the type of power supply: It can be divided into DC motors and AC motors.
(1) DC motors can be divided according to structure and working principle: brushless DC motors and brushed DC motors. Brushed DC motors can be divided into: permanent magnet DC motors and electromagnetic DC motors. Electromagnetic DC motors are divided into: series-excited DC motors, shunt-excited DC motors, separately-excited DC motors and compound-excited DC motors. Permanent magnet DC motors are divided into: rare earth permanent magnet DC motors, ferrite permanent magnet DC motors and alnico permanent magnet DC motors.
(2) Among them, AC motors can also be divided into: single-phase motors and three-phase motors.
According to the structure and working principle, it can be divided into: DC motors, asynchronous motors, and synchronous motors.
(1) Synchronous motors can be divided into: permanent magnet synchronous motors, reluctance synchronous motors and hysteresis synchronous motors.
(2) Asynchronous motor can be divided into: induction motor and AC commutator motor. Induction motors can be divided into three-phase asynchronous motors, single-phase asynchronous motors and shaded-pole asynchronous motors. AC commutator motors can be divided into: single-phase series motors, AC and DC dual-purpose motors and repulsion motors.
