Document Type and Number:
WIPO Patent Application WO/2023/136332
Kind Code:
A1
Abstract:
This electric motor comprises a stator in which an outside magnetic field section and an inside magnetic field section are provided to form a magnetic field, and the outside magnetic field section and the inside magnetic field section are formed into substantially tubular shapes by arranging permanent magnets in a circumferential direction, the permanent magnets having magnetization directions that are changed according to the number n of divisions, the number n of divisions being an integer greater than or equal to 3. Further, tubes made from ferromagnetic materials are arranged between the outside magnetic field section and the inside magnetic field section, and a coil is attached to the tubes. With this structure, the electric motor can cool the coil effectively through the tubes.
