摘要

Actuator drive device provided with a drive control unit (4) by the drive-controlled electric motor (2) ( In 1), and detects the charge state of the intermediate circuit capacitor (5) in the intermediate circuit for supplying a drive control unit (4) (3), so that it is possible to avoid a critical charge state of the intermediate circuit capacitor (5) and detected It adjusts the power consumption of the electric motor (2) according to the state of charge.
