Title:
MAGNETIC FIELD GENERATING DEVICE, AND ROTATING ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/054472
Kind Code:
A1
Abstract:
A field magnet holder provided in a field portion of an electric motor is formed from a non-magnetic material, and a plurality of spacers are arranged with a prescribed spacing in the circumferential direction between an inner wall and an outer wall each formed with a cylindrical shape. Sockets into which permanent magnets are inserted are formed between the spacers in the field magnet holder, and a plurality of said sockets are formed in the circumferential direction. As a result, the permanent magnets can be easily assembled by inserting the permanent magnets into each socket, improving the ease of assembly of a plurality of permanent magnets that are arranged in such a way that the magnetization directions thereof change sequentially at each angle obtained by dividing one electrical angle cycle by a number n of divisions, where the number n of divisions is any integer equal to or greater than 3.
