Dynamic diagram of various motor principles

A motor (commonly referred to as "motor") refers to an electromagnetic device that converts or transmits electrical energy in accordance with the law of electromagnetic induction. Its main function is to generate drive torque as a power source for electrical appliances or various machines.

The motor is divided according to the type of working power

The motor is divided according to structure and working principle

The motor is divided according to the starting and running modes

The motor is divided according to the structure of the rotor

1. A permanent magnet motor is a motor that uses a permanent magnet to provide a magnetic field. Motor work requires two conditions, one is the presence of a magnetic field, and the other is the presence of a moving current in the magnetic field.

2. A DC motor is a motor that converts DC power into mechanical energy. Due to its good speed regulation performance, it is widely used in power drag.

The excitation mode of a DC motor refers to the problem of how to supply power to the field winding and generate a field magnetomotive force to establish a main magnetic field.

3, quantum magneto

4, single-phase induction motor is used in power applications with only single-phase power supply, driving small machinery, such as small crushers, grinders, etc., the general power is less than 1500W.

5. A stepping motor is an open-loop control element that converts an electrical pulse signal into an angular displacement or a linear displacement. Its working principle is to use electronic circuit to supply DC power when component is changed. Multi-phase timing control current, use this current to supply stepper motor, stepper motor can work normally, drive is time-sharing for stepper motor , multiphase timing controller.
