What motors are suitable for neodymium iron boron magnets?

Neodymium iron boron magnets are used in permanent magnet motors. Common permanent magnet motors include permanent magnet DC motors and permanent magnet AC motors. Permanent magnet DC motor: brushed DC motor, brushless motor, stepper motor, etc. Permanent magnet AC motor: synchronous permanent magnet motor, permanent magnet servo motor, etc., can also be divided into permanent magnet linear motor and permanent magnet rotary motor according to the motion mode.

Due to the excellent magnetic properties of rare earth permanent magnet materials, a permanent magnetic field can be established without any additional energy after magnetization. Rare earth permanent magnet motors made by replacing traditional electric fields with motors not only have high efficiency, but also have a simple structure, reliable operation, small size, and light weight. It can not only achieve high performance that traditional electric excitation motors cannot match (such as ultra-high efficiency, ultra-high speed, ultra-high response speed), but also meet the specific operating requirements of special motors, such as elevator traction motors, automotive motors, etc. By combining rare earth permanent magnet motors with power electronics technology and microcomputer control technology, the performance of magnetic rotors and transmission systems has been improved to a new level. Therefore, improving the performance and level of supporting technical equipment is an important development direction for the automotive industry to adjust its industrial structure.

Rare earth permanent magnet motors are widely used in 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, AC permanent magnet servo motors, permanent magnet linear motors, special permanent magnet motors, and related control systems, covering almost the entire motor industry. The mechanism and principle of rare earth permanent magnet motor The structure of rare earth permanent magnet synchronous motor mainly consists of rotor, end cover, stator, etc. Generally speaking, the stator structure of permanent magnet synchronous motors is very similar to that of ordinary induction motors, but the unique structure of the rotor is mainly different from other motors.

The biggest difference between Tesla's AC induction motors is that they have high-quality permanent magnet poles on their rotors. Permanent magnet synchronous motors (PMSM) are usually divided into three categories: embedded, end face mounted, and plug-in, because the position of the permanent magnet on the rotor is varied. Similar to their working principle, when three-phase current is connected to a fixed motor stator winding, a rotating magnetic field is formed. This is because permanent magnets are installed in the rotor, so the permanent magnets are fixed under the action of magnetic poles. The rotating magnetic field generated in the rotor will drive the rotor to rotate.
