Document Type and Number:
WIPO Patent Application WO/2022/075317
Kind Code:
A1
Abstract:
A motor unit 1 comprises: an electrical motor 2; and a housing 4 that stores a main substrate 3 in which a control circuit 30 for the electrical motor is formed. A power supply circuit C for the electrical motor 2 is formed by connecting a bus bar 51 and a power source connector 6 via the control circuit 30. The main substrate 3 is disposed along the axial direction. Respective terminals 52, 6b of the bus bar 51 and the power source connector 6 disposed at one side and the other side in the axial direction are fitted into the main substrate 3, whereby the bus bar 51 and the power source connector 6 are electrically connected via the control circuit 30, and the main substrate 3 is positioned in the axial direction with respect to the housing 4. Further, the motor unit 1 has a structure capable of absorbing the positional misalignment, in the axial direction, of the bus bar 51 with respect to the main substrate 3.
