Title:
MOTOR
Document Type and Number:
Japanese Patent JP2022175072
Kind Code:
A
Abstract:
To reduce a length in an axis direction.SOLUTION: A motor includes a stator and a substrate. The stator includes a plurality of magnetic bodies arranged in the circumferential direction, and coils wound around the respective magnetic bodies. The substrate faces the stator in the rotational axis direction. The coils each include a first layer and a second layer that is deposited on the first layer. When the thickness of each magnetic body in the rotational axis direction and the width of each magnetic body in the radial direction are defined as L and D, respectively, 1≤D/L is established. The second layer is the furthest layer from the magnetic body. In the radial direction, a conductive wire of the first layer and a conductive wire of the second layer, which form an inner edge of the coil, are in contact with each other. In the radial direction, a conductive wire of the first layer and a conductive wire of the second layer, which form an outer edge of the coil, are in contact with each other.SELECTED DRAWING: Figure 4
