摘要： There is provided an actuator including a motor and a case adapted to house the motor. In the actuator, an output shaft of the motor is supported by a structured configured such that an elastic member is disposed between the case and at least one end of the output shaft, wherein the elastic member is in contact with a portion of the case in an engaging manner whereby the elastic member is prevented from shifting relative to the case in the rotation direction of the output shaft, and also wherein the elastic member is in contact with a portion of the motor in an engaging manner whereby a body of the motor is prevented from shifting relative to the elastic member in the rotation direction of the output shaft.

摘要： In a method of detecting synchronization loss in a stepping motor, a means for applying either control current or control voltage to a coil of each phase to thereby drive a stepping motor and a means for individually measuring a back EMF voltage induced at the coil of each phase are employed, wherein application of either the control current or the control voltage at the coil of each phase is halted by turns phase by phase for such a short time period as not to affect rotation of a rotor of the stepping motor at a predetermined timing within one step period of the rotor, the back EMF voltage at the coil is measured during the short time period, and the stepping motor is judged to lose synchronization when the measurement result of the back EMF voltage at the coil of at least one phase satisfies a detection criterion.
