Title:
ROTATING ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/189824
Kind Code:
A1
Abstract:
When a front reference position (Pf) is set as the intersection point of a front virtual line (L1) and the outer circumferential surface of a rotor core (31) in a plan view, said front virtual line (L1) passing through the central axis (O) of the rotor core (31) and the front end of a permanent magnet (32) of each set, and a rear reference position (Pr) is set as the intersection point of a rear virtual line (L2) and the outer circumferential surface of the rotor core (31) in the plan view, said rear virtual line (L2) passing through the central axis (O) of the rotor core (31) and the rear end of the permanent magnet (32) of each set, the rear end (39) of a front bridge (39f) is disposed at a position apart from the front reference position (Pf) in the rear direction (R) by an central angle about the central axis (O) of θa/24 (radian) to θa/8 (radian), inclusive, and the front end (39r1) of a rear bridge (39r) is disposed at a position apart from the rear reference position (Pr) in the front direction (F) by an central angle about the central axis (O) of 0 (radian) to θa/12 (radian), inclusive. The above θa satisfies the following equation (1). (1): θa = 2π/(Nslot)
