Document Type and Number:
WIPO Patent Application WO/2023/026781
Kind Code:
A1
Abstract:
A rotary electrical machine (100) comprises a cylindrical stator (130) that generates a magnetic field, a rotor (150) that generates torque through the magnetic field, and a housing (101) that accommodates the stator. The housing comprises a housing body (110) covering an outer circumferential part of the stator, and a housing lid part (120) attached to one end side of the housing body. The stator comprises a stator core (131) having a plurality of teeth, and a stator coil (140) mounted on the stator core, and the stator coil has a plurality of windings (141) wound onto the plurality of teeth, and a crossover wire (170) connecting at least two of the plurality of windings. The crossover wire (170) comprises an insertion mechanism (180) that is provided to the housing lid part (120) and electrically connects end parts of the windings (141) and an end part of the crossover wire (170) through insertion contact.
