Abstract
A motor according to the present invention includes an output axis, a brake for holding the output axis, a sensor for detecting an external torque applied to the output axis from outside, and a controller for decreasing or increasing the torque of the brake during operation of the brake in accordance with an increase or decrease in the external torque detected by the sensor.
Claims6
A motor comprising:
- an output axis;
- a brake for holding the output axis by applying a brake torque, the output axis being locked when the brake torque is applied on the output axis;
- a sensor for detecting an external torque applied to the output axis from outside;
- and
- a controller for decreasing or increasing the brake torque during operation of the brake in accordance with an increase or decrease in the external torque detected by the sensor so as to rotate the output axis.
