Title:
ROTATING ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/066487
Kind Code:
A1
Abstract:
The present invention relates to a rotating electric device such as an electric motor, a generator, or the like. The present invention provides a rotating electric device comprising: an outer stator (210) comprising an outer stator iron core (211) having a plurality of outer stator winding slots (213) formed on the inner peripheral surface thereof at a predetermined interval in the circumferential direction, and an outer winding (510) wound around an outer stator iron core tooth (218) relatively formed by a pair of outer stator winding slots (213) adjacent to each other; an inner stator (220) comprising an inner stator iron core (221) having a plurality of inner stator winding slots (223) formed on the outer peripheral surface thereof at a predetermined interval in the circumferential direction; and a rotor (300) having, between the outer stator (210) and the inner stator (220), a first gap (610) with regard to the outside and a second gap (620) with regard to the inside, the rotor (300) having a plurality of rotor iron cores (340) and a plurality of permanent magnets (330) installed to be able to rotate, the permanent magnets (330) being coupled between the rotor iron cores (340) along the circumferential direction. The outer stator iron core (211) has at least one outer stator iron core slot (212) formed on the inner peripheral surface thereof to be concave between a pair of outer stator winding slots (213) adjacent to each other. The inner stator iron core (221) has at least one inner stator iron core slot (222) formed on the outer peripheral surface thereof to be concave between a pair of inner stator winding slots (223) adjacent to each other.
