Title:
かご形誘導巻線導体を有する永久磁石式回転子を備えた三相同期機、および牽引駆動装置ならびに生産機械装置
Document Type and Number:
Japanese Patent JP4772503
Kind Code:
B2
Abstract:
The aim of the invention is to achieve a high torque yield in synchronous machines excited by permanent magnets. Said aim is achieved by using subharmonic air gap fields. The rotor comprises an induction cage as well as permanent magnets. The number of winding holes of the stator is greater than q=0.5. The number of poles of the rotor is greater than the base number of poles of the air gap field produced by the windings.
