Permanent magnet motor is an emerging type of motor which uses permanent magnet to generate magnetic field. It is mainly composed by stator and rotor. In comparison with traditional motors, permanent magnet motors have the advantages of higher efficiency, smaller volume and lighter weight.
High-energy permanent magnets composed of rare earth NdFeB materials are employed to excite the magnetic field in permanent magnet synchronous motors. This enables such motors to achieve substantial reductions in size and weight. The absence of a rotor winding and the compact rotor size contribute to enhanced efficiency in these motors.
Using high-efficiency NdFeB permanent magnets, no excitation loss, through structural design, the iron loss and stray loss are greatly reduced, and the efficiency of the whole machine is above IE4.
The liquid cooled permanent magnet motor is a type of electric motor that utilizes permanent magnets for its operation, and it incorporates a liquid cooling system to manage the heat generated during its operation.
Almost all major industries require the use of motors, which can be found wherever there is mechanical movement. They leverage the force of magnetism to generate rotational motion.
The PMSM stands out due to its exceptional performance, boasting characteristics such as high power density, remarkable efficiency, reduced mass, and lower moment of inertia.
