飛行体用の電動アクチュエータ装置及び駆動方法

Japanese Patent JP7201010

B2

This electric actuator device for a flying object comprises: an inner rotor motor that is mounted on the flying object and generates thrust for the flying object; a motor driver that supplies a drive signal to the inner rotor motor; a flying object power source that serves as a driving source of the flying object; and an extended function module that outputs, to the motor driver, a signal for controlling a current supplied from the flying object power source to the motor driver. The extended function module has at least one among: an inrush limitation module in which a signal for limiting an inrush current when the motor driver starts up is output to the motor driver; a regeneration processing module in which a signal for preventing an increase in a voltage due to regenerative power generated when the inner rotor motor is decelerated is output to the motor driver; and a backflow prevention module in which a signal for preventing backflow of the current due to the regenerative power generated when the inner rotor motor is decelerated is output to the motor driver.
