Title:
FIELD WINDING-TYPE ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/066482
Kind Code:
A1
Abstract:
This field winding-type rotary electric machine (30) is provided with a stator (50) and a rotor (60).The stator has: teeth (52) circumferentially provided side-by-side and radially protruding from a stator core; and a stator winding (31) wound onto the teeth. The rotor has: a plurality of main pole units (62) circumferentially provided side-by-side and radially protruding from the rotor core toward the stator side; and a field winding (70) wound on to the main pole units. Each of the main pole units extends axially. When sections at both ends of the main pole units in the circumferential direction and facing the stator in the radial direction are referred to as main pole end sections (64a, 64b), notches (65a, 65b) are formed in axial portions of at least one among the pair of main pole end sections constituting the main pole units.
