What is the function of the motor magnet?

Motor magnets are an indispensable and important part of motors. It can generate a magnetic field, which drives the rotation of the motor. So what exactly does a motor magnet do? This article will elaborate on the application of motor magnets in motors from the following six aspects.

The interaction of the motor magnet with the motor rotor.

In an electric motor, the magnetic field of the motor magnet interacts with the magnetic field of the motor rotor, thereby driving the rotor to rotate. This interaction is caused by the interaction of magnetic inductive lines, in which the magnetic field formed by the armature coil around the core interacts with the magnetic field formed by the permanent magnet, causing the rotor to rotate.

The interaction of the motor magnet with the motor stator.

In an electric motor, the magnetic field of the motor magnet interacts with the magnetic field of the motor stator, thereby converting electrical energy into mechanical energy. This interaction is formed by the interaction of the magnetic field generated in the coil connected in series with the stator winding with the magnetic field in the magnet.

The position of the motor magnet on the motor rotor.

In a motor, the motor magnet is usually mounted on the rotor and can be an elongated cylindrical magnet or a monolithic magnet composed of multiple arc-shaped magnets.

Application of motor magnets in wind turbines.

A wind turbine is a device that converts wind energy into electricity. In wind turbines, the role of the motor magnet is to generate a stable magnetic field, so that the rotor windings induce electrical energy and are transmitted to the grid.

Application of motor magnets in maglev trains.

A maglev train is a high-speed train that works by using electromagnetic force. The function of the motor magnet in the maglev train is to generate a static magnetic field, so that the train is suspended on the track, and drive the train movement by adjusting the size and direction of the magnetic field.

Application of motor magnet in computer hard disk.

The read/write head in a computer's hard disk is able to read and write data from the disk because of the action of the motor magnet. The data on the disk is represented by creating different magnetic fields in small areas on the surface of the disk. The motor magnet on the read/write head can change the magnitude and direction of the magnetic field to read or write data.

Through the elaboration of the above six aspects, I believe that everyone has a deeper understanding of the application of motor magnets in motors. As an important part of the motor, the motor magnet plays an important role in driving the mechanical operation.
