Title:
RADIAL GAP ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/142653
Kind Code:
A1
Abstract:
The present invention according to one aspect has a configuration, in which six phase coils in two concentratedly wound three-phase coils in a tandem motor are arranged in the circumferential direction by at least either a pole number-doubling arrangement that doubles the number of poles or a phase number-doubling arrangement that doubles the number of phases. The present invention according to another aspect has a configuration, in which an insulating conductor of a distributedly wound stator coil in a tandem motor alternately penetrates a slot of a front stator core and a slot of a rear stator core. This insulating conductor is bent in the circumferential direction between the front stator core and the rear stator core. The present invention according to still another aspect has a configuration, in which a front motor mainly generates a magnetic torque and a rear rotor core mainly generates a reluctance torque. The present invention according to a further aspect has a configuration, in which a front stator core and a rear stator core each are composed of a T-shaped core segment. Preferably, a housing has a diecast fitting part that mechanically joins to a wedge part of the core segment.
