Title:
ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/189825
Kind Code:
A1
Abstract:
When, as seen in plan view, a front reference position (Pf) is designated as the intersection point of a front virtual line (L1) that passes through the central axis (O) of a rotor core (31) and the front edge of a front magnet (32f), and the outer peripheral surface of the rotor core (31); and a rear reference position (Pr) is designated as the intersection point of a rear virtual line (L2) that passes through the central axis (O) of the rotor core (31) and the rear edge of a rear magnet (32r), and the outer peripheral surface of the rotor core (31), the front edge of a rear bridge (39r) is disposed in a position set apart toward the front (F) with respect to the rear reference position (Pr) by θf (rad) at a central angle centered on the central axis (O), and a rear edge (39f1) of the front bridge (39f) is disposed at a position set apart toward the front (F) with respect to the front reference position (Pf) by at least 0 (rad) and no greater than θf (rad) at the central angle centered on the central axis O. θf is defined as shown in formula (1) and formula (2). (1) 0<θf≤(θa/8) (2) θa=2π/(Nslot)
