Document Type and Number:
WIPO Patent Application WO/2013/073416
Kind Code:
A1
Abstract:
Provided is a dynamo-electric machine configured so that the influence of pulsating torque on the rotation of the rotor is reduced to allow the rotor to rotate smoothly.
A dynamo-electric machine comprises: a rotor which is provided with permanent magnets arranged coaxially with the rotating shaft at equal intervals so as to be parallel to the rotating shaft and such that the magnetization directions alternate, and also with magnetic bodies provided between the permanent magnets while non-magnetic bodies are sandwiched between the magnetic bodies; stator cores which are disposed so as to connect the front face ends and rear face ends of the permanent magnets while air gaps are provided between the stator cores and the front and rear face ends; and coils wound on the stator cores.
