Both at home and abroad, the design and analysis of high-speed motor still have some problems that need to be solved.Specifically, there are several problems in the design and analysis of high-speed motor.
High-speed motor generally refers to the motor whose speed exceeds 10,000 r/min or whose difficulty value exceeds 100,000. At present, the main high-speed motors are induction motor, inner rotor permanent magnet motor, switched reluctance motor, a few outer rotor permanent magnet motor and claw pole motor.
The high speed motor is characterized by its small size and large power density, which can be directly connected with the high speed load, eliminating the traditional mechanical increasing device, reducing the system noise, and improving the system transmission efficiency.High-speed motor can be used in a wide range of fields, including high-speed grinder, fuel cell, energy storage flywheel, international electrician and other fields, with a good market prospect.
