Japanese Patent JP2022158985
Kind Code:
A
Abstract:
To provide a motor capable of reducing electromagnetic interference caused in a hall element by a busbar and improving the magnetic detection accuracy of the hall element.SOLUTION: A motor includes a rotor 10, a stator 20 arranged to face the rotor 10 in a radial direction, a bearing holder 30 located on one side of the rotor 10 in an axial direction, a busbar holder 40 located on one side of the bearing holder 30 in the axial direction, and a housing 50 for accommodating the rotor 10, the stator 20, the bearing holder 30 and the busbar holder 40. An induced magnetic loop M is arranged on one side of the bearing holder 30 in the axial direction, and the busbar holder 40 encloses the busbar 41 therein. A circuit board 42 is arranged on a surface on the other side of the busbar holder 40 in the axial direction, and a Hall element H is arranged on a surface on the other side of the circuit board 42 in the axial direction. The Hall element H and busbar 41 are arranged at different positions in a circumferential direction.SELECTED DRAWING: Figure 1
