Abstract
Switching elements are mounted on a substrate and switch energization of motor windings. A lead wire set connects phase coils of the motor windings to the substrate. The switching elements, the lead wire set, a power terminal which is a power supply terminal and a ground terminal, and a control circuit unit are provided for each system. The switching elements, the lead wire set and the power terminal are collectively arranged in a power region for each system, and the lead wire sets are arranged in rotational symmetry.
