Abstract: A rotor for a rotating electrical machine includes a rotor core body that includes a bridge through which a first inner surface is connected to a second inner surface of an innermost flux barrier when the rotor core body is viewed in an axial direction of a rotor core. The innermost flux barrier has an outer-side closed space that is a defined space and is formed between the bridge and an outer periphery of the rotor core body. The outer diameter closed space is filled, in the axial direction of the rotor core body, with a reinforcing part that is made of a non-magnetic material.

Abstract: A stator of a rotary electric machine includes a stator core and polyphase coils. The stator core has a plurality of slots. The polyphase coils are provided in the slots. Each phase of the polyphase coils has a plurality of coils formed for each pole and connected in parallel. When winding in which a coil pitch is equal to number of slots divided by number of poles is termed full-pitch winding, when winding in which a coil pitch is larger than the coil pitch of the full-pitch winding is termed long-pitch winding, and when winding in which a coil pitch is smaller than the coil pitch of the full-pitch winding is termed short-pitch winding, at least two of the coils of each phase are formed on the stator core by wave winding to alternate between the long-pitch winding and the short-pitch winding along a circumferential direction of the stator core.

Abstract: A rotary electric machine includes a rotor core, a stator, a field yoke, and a field winding. The rotor core is fixed to a rotary shaft, which includes a magnetic body for forming a magnetic path, and magnetic salient poles. The stator has teeth and a stator winding wound around the teeth by concentrated winding. A slot is formed between adjacent ones of the teeth in a circumferential direction. The field yoke magnetically connects the stator and the magnetic body. The field winding is located in proximity to at least one of the winding ends of the stator winding in an axial direction of the rotary shaft. The field winding generates a magnetic pole on the magnetic salient poles when energized.
