PROBLEM TO BE SOLVED: To provide a control device of an electric actuator, capable of easily changing the setting of a torque limit value. SOLUTION: A level of the manipulated variable control signal from a controller 7 for controlling the rotational speed of a rotor of a brushless motor 22 to be detected in cooperation with a sensor 3 and a speed detecting means 4 to the speed, based on the speed pattern generated in cooperation with a speed profile generator 1 and a speed limiter 2, is limited to the level of the torque limit controlled value signal to be fed to a torque limiter 8. The torque of the brushless motor 22 to be detected by a torque-converting means 10 is controlled to the level of a torque limit controlled value signal, by controlling the energizing quantity of the brushless motor 22, based on the manipulated variable control signal to be outputted through the torque limiter 8, in cooperation with of a PWM modulation circuit 12 and an inverter circuit 13. |
