Title:
ROTATING ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/022202
Kind Code:
A1
Abstract:
Three-phase windings (55, 56) are energized so that the phase difference θe1 between the respective sets is 30 ± 60 × n [deg] in electric angle. θe1 > θe2. When the radial distance between the teeth (76) and the circumscribed circle (Cc) of a rotor core (64) is a, and the radial distance from outermost magnet portions (86, 87) that are positioned on the radially outermost side of a permanent magnet (65) to the circumscribed circle (Cc) is b, a/b < 1.
