    Abstract: An electric motor system includes a brushless direct-current motor, a driver circuit, a position sensor, and a control circuit. The motor has an output shaft for transmitting torque. The driver circuit supplies power to the motor according to a control signal input thereto. The position sensor measures an angular, rotational position of the motor shaft. The control circuit controls operation of the motor. The control circuit includes a position sensor terminal, a reference terminal, a differential calculator, a controller, and a gain adjuster. The position sensor terminal receives a feedback signal. The reference terminal receives a reference signal. The differential calculator generates an error signal representing a difference between the measured and targeted rotational positions. The controller generates the control signal based on the error signal through a combination of control actions. The gain adjuster is connected to the controller to adjust a gain of each control action.

    Abstract: A drive transmitter is provided that includes an electromagnetic clutch, an energization part integrated with the electromagnetic clutch and to be electrically connected to a connection part of a device body, a field core integrated with the energization part, a rotor boss part, and a tilt restrictor in engagement with the energization part. The tilt restrictor restricts tilting of the field core to the rotor boss part when an external force is applied to the energization part from the connection part in electrical connection with the energization part.

    Abstract: A fire-spread prevention member is interposed between an electrical component and a combustible member. The fire-spread prevention member includes a bent portion that is disposed outside an outer edge of the electrical component and bent to a side on which the electrical component is disposed. The fire-spread prevention member is made of non-combustible material.
