Permanent Magnet Synchronous Motor Magnet

Introduction

Permanent magnet motor is a type of motor that uses the magnetic field of permanent magnet rather than exciting winding in the motor.

Classification

Permanent magnet synchronous motors (PMSMs) are a type of electric motor that use permanent magnets to generate the magnetic field necessary for operation. PMSMs can be classified based on various factors, including their construction, control method, and application.

Here are some common classifications of permanent magnet synchronous motors:

Based on Construction:

lSurface-mounted permanent magnet synchronous motor (SPMSM)

lInterior permanent magnet synchronous motor (IPMSM)

lBuried permanent magnet synchronous motor (BPMSM)

lHalbach permanent magnet synchronous motor (HPMSM)

l 

Based on Control Method:

lField Oriented Control (FOC) PMSM

lDirect Torque Control (DTC) PMSM

lVector Control PMSM

Based on Application:

lIndustrial PMSM (for industrial applications such as fans, pumps, and compressors)

lAutomotive PMSM (for electric vehicles)

lAerospace PMSM (for aerospace applications such as satellite attitude control)

lConsumer Electronics PMSM (for household appliances such as washing machines and vacuum cleaners)

Each type of PMSM has its own advantages and disadvantages, making it suitable for different applications.

AC Motor

1.Synchronous Generator: single phase AC power supply, three phase AC power supply, auxiliary exciter and wind-driven generator.

2.AC Speed Measuring Motor: speed measurement of flight, navigation, locomotive and lathe.

3.Induction Generator: single phase medium frequency power supply.

4.Ignition Magneto: ignition system of the internal combustion engine of the locomotive, train and aircraft.

5. Synchronous Motor: pumping unit, blowing machine, water pump and textile machine.

DC Motor

1.DC Motor:micro-motor in the camera, domestic appliance, electronic industry, instrumentation and electrical toy.

2.DC Servo Motor: automation and remote control system.

3.DC Speed Measuring Motor: measuring revolution of various rotating parts.

4.DC Torque Motor: elevator and aviation.

5.Other Motors: including stepper motor, DC brush less motor, piezoelectric motor, hall motor and voice coil motor, and widely used in industrial automation, office automation, remote control system and computer peripherals.
