モータ制御装置
Document Type and Number:
Japanese Patent JP7415891
Kind Code:
B2
Abstract:
A first circuit (68, 681, 682) supplies electric power to a polyphase motor (800). A second circuit (67) supplies electric power to a direct-current motor (720, 730) for outputting a torque so as to move a movable body (24) in a section movement actuator (20, 30) configured to enable the movable body to move in a predetermined section. Assuming that a pair of high-electric-potential-side and low-electric-potential-side switching elements connected in series in the first circuit and the second circuit are defined as a leg, the first circuit and the second circuit form an integrated power conversion circuit (60) sharing a single leg. A control unit (400) has an end abutment determination unit (50) for determining end abutment, which indicates that the movable body of the section movement actuator is brought into abutment with an end of the section, during the supply of the electric power to the direct-current motor.
