ELECTRIC MOTOR
Document Type and Number:
Japanese Patent JP2023167903
Kind Code:
A
Abstract:
To provide an electric motor capable of enhancing an arrangement degree-of-freedom of a magnetic sensor for detecting a rotational position of an outer rotor.SOLUTION: An outer rotor 4 comprises: a cylinder rotor yoke part 25 that is opposite to an outer peripheral surface 17a of a stator core 17 to a radial direction; a plurality of leg parts 26 that is projected toward a shaft direction outer side from an end part 25b side of the rotor yoke part 25; a bottom part 27 that is bonded to an end opposite to the rotor yoke part 25 in the plurality of leg parts 26, and is opposite to a shaft direction with an end surface 17b of the stator core 17; and a plurality of magnets 24 that is fixed to an inner peripheral surface 25a of the rotor yoke part 25. In each of the plurality of magnets 24, an end part 24a on at least bottom part 27 side is projected from the end part 25b of the rotor yoke part 25, and is interposed between the adjacent leg parts 26 in a peripheral direction.SELECTED DRAWING: Figure 1
