AXIAL GAP TYPE DYNAMO-ELECTRIC MACHINE

摘要

An axial gap type dynamo−electric machine,comprising disk−like rotor side yokes fixed to a rotating shaft,disk−like stator side yokes(23)opposed to the rotor side yokes,magnets fixed to the sides opposed to either of the rotor side yokes and stator side yokes,a plurality of teeth(24)radially disposed on the sides opposed to the other of the rotor side yokes and stator side yokes,and coils(25)wound on the plurality of teeth,the yoke(23)further comprising fixing parts formed of holes or recesses for fixedly inserting a part of the teeth(24)and resistance parts(slits 36)against an induced current are provided around the fixing parts,whereby an axial gap type electric motor capable of providing a high motor efficiency with a small size can be provided as a high torque drive source using intense magnets by reducing an energy loss due to the induced current.
