Permanent magnet (PM) motor is a kind of AC motor, which uses magnets embedded in or connected to the rotor surface of the motor. Electric vehicle adopts permanent magnet synchronous motor, which has high torque density and high efficiency.
Permanent magnet motors are favored in high-speed applications because of their high efficiency, high power factor and wide speed range. Compared with the external rotor permanent magnet motor, the internal rotor permanent magnet motor has the advantages of small rotor radius and strong reliability, and becomes the first choice for high-speed motors. The working environment of the motor also requires the use of permanent magnet materials with high strength and high temperature resistance, so most high-speed permanent magnet motors choose NdFeB permanent magnet materials.
NdFeB is widely used in high speed motors because of high BH, high Hcj and small volume. Our product range includes all grades of magnets,various high-precision shapes and sizes, to satisfy all the performance requirements of high speed motor manufacturers.
AOMAG focus on high performance magnets and provides perfect rare earth permanent magnets solutions. AOMAG Magnetics keep continuous technical innovation. We have been researching and producing high performance and high temperature resistant NdFeB motor magnets for 28 years.
