A measurement circuit that is configured to provide a torque reading to a motion controller includes an offset controller and an amplifier. The offset controller is configured to read a temperature signal and to generate an offset voltage in response to receiving the temperature signal. The amplifier is configured to read a differential voltage from a differential sensor and to receive the offset voltage from the offset controller. The amplifier is also configured to add the offset voltage to the differential voltage after applying a gain to the differential voltage to generate an adjusted voltage. The amplifier is then configured to transmit the adjusted voltage.

According to one aspect of the present disclosure, a driving device is a driving device for rotating an axle of a vehicle and includes: a motor having a rotor rotating about a motor axis extending in a horizontal direction orthogonal to a vertical direction; a reduction gear connected to the rotor; a differential gear connected to the motor via the reduction gear; and a housing configured to house the motor, the reduction gear and the differential gear therein. The housing has a protrusion that protrudes upward in the vertical direction, and at least one circumferential rib that extends in a circumferential direction. The protrusion has a female screw hole into which an eye bolt can be tightened. At least one of the circumferential ribs is connected to the protrusion.

It is provided an actuated machine having a main frame, a machine shaft mounted on the main frame by means of a bearing module, a gearless torque motor coupled to the machine shaft for driving a rotation of the machine shaft, a torque arm coupled to the gearless torque motor, and a catching structure. The gearless torque motor is coupled to the machine shaft 200 such that the gearless torque motor is capable of following a translational movement of the machine shaft. The torque arm is coupled to the gearless torque motor for inhibiting a rotational motion of the gearless torque motor, relative to the main frame, about a central axis of the gearless torque motor. The catching structure is arranged underneath the gearless torque motor for catching and holding the gearless torque motor in case of a failure causing the gearless torque motor's weight to be no longer carried by the machine shaft.
