DRIVE DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2020/110889
Kind Code:
A1
Abstract:
A motor (500) has a winding (510). A power conversion device (400) converts DC power to AC power and supplies same to the motor. A housing (H): forms a motor housing chamber (R2) that houses the motor and a power conversion housing chamber (R1) that houses the power conversion device, therein; and has partitioning walls (404) that partition the motor housing chamber and the power conversion housing chamber. A conductive member (10): is arranged inserted in a through-hole (404a) formed in a partitioning wall; and electrically connects the power conversion device and the winding. An insulating member (20) is attached to the through-hole and is interposed between and electrically insulates the conductive member and the partitioning walls. Seal mechanisms (30, 22c) seal between the insulating member and the partitioning walls so as to suppress inflow of air from the motor housing chamber to the power conversion housing chamber via the through-hole.
