ELECTRIC ACTUATOR DRIVE DEVICE

摘要

The present invention enables greater compactness and lightweightness in addition to being able to be applied to transient, large, instantaneous current arising during electric actuator acceleration. The present invention is an electric actuator drive device having an electric actuator (10) and a generator motor (50) for driving the electric actuator (10), wherein the electric actuator drive device has a generator motor drive means (C8) that rotationally drives the generator motor (50) in a manner so as to be at a rotational frequency at which large, instantaneous current arising during electric actuator (10) acceleration/deceleration is delivered.
