New development of rare earth permanent magnet in China;

The effect of magnetic performance and geometry parameters as well construction parameters of rare earth permanent magnet on magnetic fluid seals capacity were investigated with ANSYS software.

When the metal belt transmission with rare-earth permanent magnets assistance running,the permanent magnets distributed at interval on the pulley cause periodic excitation,which result in transverse vibration of the metal belt and so harmful to the metal belt transmission.

The development and demand analyse of rare earth permanent magnet in China;

Study on parameter test system of rare earth permanent magnet synchronous machines based on computer;

The rare earth permanent magnet synchronous motor introduced in the paper is designed for the well pumping unit.

Research and development of rare-earth permanent magnet machines;

The Nd-Fe-B alloy is named as "the 3~(rd) generation of rare-earth magnets",and becomes into a rare-earth permanent magnet with the fastest industrialization and increase rate by means of its excellent price/performance and performance improvement.

Based on the study on the electric steady voltage of the rare-earth permanent magnet generating set on the vehicle,a creative design of generating set s windings are applied to make the output voltage of generating set stabilize.
