Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/176166
Kind Code:
A1
Abstract:
This motor control device controls a motor having the winding groups of two systems. The motor control device has a substrate (42) and sensors (71A, 71B) provided on the substrate (42) and configured so as to generate electrical signals in accordance with the rotation of the motor. The substrate (42) has a first region (A1) and a second region (A2) which are divided from each other by a boundary line (BL). The first region (A1) and the second region (A2) respectively have: power circuit regions (A11, A12); control circuit regions (A21, A22); signal paths (R3, R4) for transmitting the electrical signals to the control circuit regions (A21, A22); and power paths (R1, R2) for transmitting the power supplied from a power supply to the power circuit regions (A11, A12). The signal paths (R3, R4) are provided so as not to traverse the power paths (R1, R2) and the power circuit regions (A11, A12) when viewed from the axial direction of the motor.
