MOTOR
Document Type and Number:
Japanese Patent JP2020162206
Kind Code:
A
Abstract:
To provide a motor capable of stably fixing a circuit board while improving the degree of freedom in a wiring pattern of the board.SOLUTION: A stator 3 comprises a stator core including a core outer peripheral surface enclosing a central axis and spread in a circumferential direction, and an insulator fixed to the stator core. The insulator includes a cylinder part extending from the stator core to one side in an axial direction and enclosing the central axis. An end face of the cylinder part at one side in the axial direction is formed polygonal in a view in the axial direction. In a circuit board 5, a pair of board surfaces is turned in the axial direction and brought into contact with the end face from one side in the axial direction. A board outer peripheral edge of the circuit board 5 is formed polygonal in a view in the axial direction. Multiple board corner parts 5d and 5e disposed in the circumferential direction are included in an outer peripheral part of the circuit board 5. A second case part 12 includes a board pressing part 12d which is in contact with the circuit board 5 from one side in the axial direction. The board pressing part 12d are overlapped with the board corner parts 5d and 5e in a view in the axial direction.SELECTED DRAWING: Figure 5
