摘要： 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.

摘要： A contact-and-separation system includes a first roller, a second roller, and a contact-and-separation device. The first roller contacts a belt. The second roller is opposed to the first roller. The contact-and-separation device contacts or separates the belt to or from the second roller via a sheet conveyed. The contact-and-separation device includes an eccentric cam, a motor, and a circuitry. The eccentric cam is mounted on an end of a rotation shaft of the first roller. The motor rotates the eccentric cam. The circuitry controls the motor to rotate the eccentric cam to contact or separate the belt to or from the second roller via the sheet conveyed. The circuitry controls the motor to decelerate a rotation speed of the motor on contact or separation of the belt to or from the second roller between the first roller and the second roller.

摘要： A drive unit, which can be included in an image forming apparatus with peripherals disposed thereto and use a control method therefore, includes an inner rotor brushless DC motor, a driver, a rotation detector, and a controller. The driver supplies power to drive the brushless DC motor. The rotation detector detects an amount and direction of rotations of an output shaft. The controller controls the rotations of the brushless DC motor and obtains a target drive signal of the brushless DC motor externally and a detection signal from the rotation detector and outputs a signal to the driver. The controller controls a speed of rotation of the brushless DC motor by varying the signal output to the driver based on the target drive signal and the detection signal.

摘要： A drive transmission device includes a rotation shaft, a drive transmitter attached to the rotation shaft to slide in an axial direction and including an engaging portion extending in the axial direction, and a coil spring to bias the drive transmitter to one side in the axial direction, and a shaft-side drive transmitter disposed on the rotation shaft. The coil spring includes a sparse portion and a dense portion. The shaft-side drive transmitter engages the engaging portion to prevent the drive transmitter from disengaging from the rotation shaft. The coil spring and the engaging portion satisfy C>A−B where A represents a length of the coil spring in a state in which the shaft-side drive transmitter retains the drive transmitter, B represents a compressed height of the coil spring, and C represents a length of the coil spring in the axial direction.

摘要： An image forming apparatus includes a housing, a unit including a drive member and being positioned to the housing, and a drive device configured to rotate the drive member in a normal direction and a reverse direction. The drive device includes a housing-side gear mounted on the housing, and a unit-side gear mounted on the unit, the unit-side gear being configured to mesh with the housing-side gear. The drive device transmits a driving force to the drive member, the driving force causes a force from the housing-side gear to the unit-side gear, the force includes a component force in a direction to detach the unit from the housing, and the component force is smaller than a static friction force between the unit and the housing.
