A permanent magnet brushless DC motor is a DC motor that establishes a magnetic field from one or more permanent magnets. Its performance is similar to that of a forced excitation DC motor with a constant excitation current, which can be easily adjusted by changing the armature voltage. Compared with the other-type DC motor, it has the advantages of small size, high efficiency, simple structure, and low copper consumption. It is the main type of low-power DC motor.

Permanent magnet DC motor

Permanent magnet DC motors can be divided into permanent magnet brushless DC motors and permanent magnet brush DC motors according to the presence or absence of brushes. A permanent magnet DC motor is a DC motor that uses a permanent magnet to establish a magnetic field. Permanent magnet DC motors are widely used in a variety of portable electronic equipment or appliances, such as tape recorders, VCD machines, record players, electric massagers and various toys. They are also widely used in automobiles, motorcycles, hand dryers, electric bicycles, and batteries. The automobile, shipbuilding, aviation, machinery and other industries are also widely used in some high-precision products, such as video recorders, copiers, cameras, mobile phones, precision machine tools, bank counters, and banknote machines.

The use of permanent magnet DC motor:

In terms of stage lighting, permanent magnet DC motors, especially small permanent magnet DC gear motors, are used in large quantities. Printers, scanners, hard drives, optical drives, recorders, cooling fans, etc. in the computer industry use a large number of permanent magnet DC motors.

Various types of permanent magnet DC motors are used in various types of fans, wipers, water jet pumps, flameouts, mirrors, and air pumps in the automotive industry. In the hotel, automatic doors, automatic door locks, automatic curtains, automatic water supply systems, toweling machines, etc. all use permanent magnet DC motors. In weapons and equipment, permanent magnet DC motors are widely used in missiles, artillery, satellites, spacecraft. , ships, aircraft, tanks, rockets, radar, chariots and other occasions.

In industrial and agricultural areas, permanent magnet DC motors are also widely used in electrical and automation control and instrumentation. In medical applications, permanent magnet DC motors are used in a variety of applications, such as medical instruments and surgical tools, such as electric saw blades in brain surgery, especially in the field of surgery. Magnetic DC motor. In the case of disabled products, such as robots, disabled cars, etc., permanent magnet DC motors are used. In terms of life, there is more use, and even the toothbrush is made of a permanent magnet DC motor. The application of permanent magnet DC motors is really indispensable. It can be said that it is everywhere.

With the development of the times, the application of permanent magnet DC motors will be more. Many of the original AC motors were replaced by permanent magnet DC motors. Especially in the case of permanent magnet brushless motors, the production of permanent magnet DC motors is constantly increasing.
