Abstract

It is desired to reduce power consumption of electric actuators. An excavator includes a first electric actuator configured to drive a first movable member, a second electric actuator configured to drive a second movable member connected to the first movable member, a brake device configured to apply a braking force to a first output shaft of the first electric actuator, and a control device. If reaction torque acting on the first output shaft as the second electric actuator outputs torque is greater than a threshold, the control device controls the first electric actuator such that the first output shaft outputs the torque in a direction opposite to the reaction torque. If the reaction torque is no more than the threshold, the control device causes the brake device to apply a braking force to the first output shaft and suspends power supply to the first electric actuator.
