  • Publication number: 20190267869
    Abstract: A drive motor includes a torque sensor on an outer circumference of a shaft. The drive motor includes a rotor, a rotor shaft arranged inside the rotor, and an output shaft that is joined to the rotor shaft by a joint having a loose element. In the drive motor, the output shaft outputs rotational force of the rotor shaft to the output side. The torque sensor is arranged on an upstream side of the joint in a range not overlapping with the joint.
