Title:
ROTATING ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/131905
Kind Code:
A1
Abstract:
This rotating electrical machine is equipped with an armature (50) and a field element (40) having a magnet portion (42). The magnet portion (42) is provided with a plurality of magnets (91, 92) that are arranged side by side with a prescribed distance therebetween in the circumferential direction. In the magnets (91, 92), the easy axis of magnetization is oriented such that said orientation becomes parallel to the d-axis on the d-axis side in comparison to the q-axis side, and the magnetic path of the magnet is formed along the easy axis of magnetization. The field element (40) is provided with a field element core (43) that is a soft magnetic body. The field element core (43) has protruding portions (1002) that protrude toward the armature side, the protruding portions (1002) are provided further toward the q-axis side than the d-axis side in the circumferential direction, and both circumferential-direction end faces (1002a, 1002b) of each protruding portion (1002) are in contact, respectively, with the circumferential-direction end faces (91a, 92a) of the magnets.
