This paper explained briefly on the meaning of characteristics, effects, economics and social benefits of popularizing the new model rare earths permanent for energy saving motors.

The Design Study of Fine Dynamic Performance Rare Earth Permanent Magnet Synchronous Motor;

which exist in the use of the ordinary asynchronous starting of rare earth permanent magnet synchronous motor were analyzed,and puts forward the way to deal with such kinds of situations.

According to the character of the rare earth permanent magnet DC coreless motor,the CAD system was programmed through C++ Builder 6.

Study on Design of the Rotor Magnetic Circuit Structure Based on Starting Characteristics of REPMSM;

Adjustable Rare Earth Permanent Magnet Synchronous Motor Speed (REPMSM) Through Varying Frequency by Self-control

Theoretically,there aren t the fundamental wave loss on the rotor of REPMSM,so the rotor temperature rise should be low,but in actual because the magnet steel eddy current loss and the overtone loss and so on the inevitable question causes the rotor to give off heat,the temperature rise increases.
