Document Type and Number:
WIPO Patent Application WO/2022/196458
Kind Code:
A1
Abstract:
A drive device (1) comprising: a motor (80) having first motor winding (180) and second motor winding (280); and a control unit (10). The control unit (10) has a connector unit (50), a main board (31), a sub-board (32), and connecting components (141, 146, 241, 246) and is provided on one side of the motor (80) in the axial direction. The main board (31) and the sub-board (32) each have a first line region and a second line region separated by the board center line. In the first line region, electronic components relating to the energization control of the first motor winding (180) are mounted, and in the second line region, electronic components relating to the energization control of the second motor winding (280) are mounted. The first line region and the second line region are each separated into a power region in which a motor current to be supplied to the motor (80) is caused to flow and a control region in which a control current relatively smaller than the motor current is caused to flow.
