ELECTRICALLY DRIVEN ACTUATOR DRIVE DEVICE

摘要

PROBLEM TO BE SOLVED: To deal with a transient large instantaneous current occurring during the acceleration of an electrically driven actuator and reduce the size and the weight of the electrically driven actuator.

SOLUTION: An electrically driven actuator drive device of this invention includes: an electrically driven actuator 10; and a power generation motor 50 for driving the electrically driven actuator 10. The electrically driven actuator drive device includes power generation motor driving means C8 rotatably driving the power generation motor 50 so that the power generation motor 50 is operated at the rotation number that feeds a large instantaneous current occurring during the acceleration and the deceleration of the electrically driven actuator 10.
