Description
Technical field
The present invention relates to a kind of permagnetic synchronous motor, particularly to a kind of permanent-magnetic synchronous motor stator punching.
Background technology
The operation logic of permasyn morot is identical with electrically excited synchronous motor, but it is with the magnetic flux of permanent magnet offer
Substitute the Exciting Windings for Transverse Differential Protection excitation of the latter.There is no current excitation, brushless and slip ring；Being lost low, efficiency is high；Power factor (PF) is high；
Rotor structure is various, flexibly；Volume is little, lightweight；Advantage that starting torque is big etc..Meanwhile, China abounds with permanent magnet material
Country's particularly rare earth permanent-magnetic material hinge ferrum boron resource is the abundantest in China, and the reserves of Rare Earth Mine are that other various countries of the world are total
About 4 times of sum, are known as " rare earth kingdom ".For China, permasyn morot has good application prospect.Give full play to
The advantage that China's rare earth resources is abundant, energetically the research and extension application various magnetoes with rare-earth permanent-magnet electric machine as representative,
To realizing the modernization of Chinese society doctrine, there is important theory significance and practical value.
