Functions of Field Magnet in Electric Motor

The detailed functions of Field Magnet in Electric Motor
The principle of magnetic field magnets working in electric motors is mainly the use of magnetic fields. The working principle of the motor is to use the energized coil to rotate under force in the magnetic field, and the magnetic field generated by the magnetic field magnet interacts with the energized coil to generate magnetic force and drive the rotor to rotate.

Specifically, the functions of the field magnet in the motor include:
• Generating a magnetic field
The magnetic field magnet is energized to generate a magnetic field that provides a rotating magnetic field for the rotor of the motor. During the operation of the motor, the magnetic field generated by the magnetic field of the magnetic field and the magnetic field of the energized coil interact to produce a magnetic force, so that the rotor is driven or pulled, so as to achieve rotation.
• Adjusting the magnetic field
By changing the current direction or strength of the magnetic field magnet, the size and direction of the magnetic field can be adjusted, and then the speed and torque of the motor can be adjusted.
• Control speed
The role of the magnetic field magnet in the motor is also to control speed. By changing the current size and direction of the magnetic field magnet, the size and direction of the magnetic field can be changed, thus changing the speed of the motor.
• Improve efficiency
Magnetic field magnets also improve efficiency in the motor. During the operation of the motor, the magnetic field magnet will produce a kind of back electromotive force, which helps to reduce the coil resistance loss and improve the efficiency of the motor.

In a whole, the function of the magnetic field magnet in the motor is primarily to generate a magnetic field, interact with the magnetic field of the energized coil, generate a magnetic force, and promote the rotation of the rotor, so as to achieve the operation of the motor. Meanwhile, the magnetic field magnet can also adjust the magnetic field, control the speed and improve the efficiency of the motor.
