Neodymium magnet, also known as NdFeB magnet, is widely used in permanent magnet motors due to its excellent magnetic properties. In this article, let’s take a closer look at the application of neodymium magnets in motors.
Common permanent magnet motors include permanent magnet DC motors and permanent magnet AC motors. Permanent magnet DC motors include brushed DC motors, brushless motors, and stepper motors, etc. Permanent magnet AC motors include synchronous permanent magnet motors, permanent magnet servo motors, and so on. Permanent magnet motors are also divided into permanent magnet linear motors and permanent magnet rotary motors according to their movement modes.
Because of the excellent magnetic properties of rare earth permanent magnet materials, a strong permanent magnetic field can be established without additional energy after magnetization. The rare earth permanent magnet motor, which is used to replace the traditional motor, is not only efficient but also simple in structure, reliable in operation, small in size, and light in weight.
It can not only achieve the high performance that traditional electric excitation motors can’t match (such as ultra-high efficiency, ultra-high speed, ultra-high response speed), but also can be made into special motors that can meet specific operating requirements, such as elevator traction motors, automotive special motors, etc.
The combination of rare earth permanent magnet motor with power electronic technology and microcomputer control technology improves the performance of the motor and transmission system to a new level.
The application range of rare earth permanent magnet motors is extremely wide, covering almost all fields of aviation, aerospace, national defense, equipment manufacturing, industrial and agricultural production, and daily life. It includes permanent magnet synchronous motors, permanent magnet generators, DC motors, brushless DC motors, AC permanent magnet servo motors, permanent magnet linear motors, special permanent magnet motors, and related control systems, covering almost the entire motor industry.
