摘要： In a stepper motor driver, a rotation detector unit determines whether the stepper motor is rotating. When the rotation detector unit detects the stepper motor at a stop, the control unit operates to increase the effective driving power and then decrease it at regular time intervals. When a field detection unit detects a magnetic field, the control unit suspends decreasing the effective driving power.

摘要： A pulse motor driving device having a rotation detecting unit adapted to detect whether or not a pulse motor rotates. In this device, a control unit performs an operation of increasing the effective value of the driving power of the pulse motor and performs an operation of lowering the effective value of the driving power thereof when it is detected by the rotation detecting unit that the pulse motor does not rotate. Further, the control unit interrupts the operation of lowering the effective value of the driving power of the pulse motor when a magnetic field is detected by a magnetic detecting unit.

摘要： An electronic apparatus having a generator that generates electric power, a storage unit in which electric energy generated by the generator is stored, and a motor driven by the electric energy stored in the storage unit, wherein it is judged whether or not a magnetic field is generated by the power generation. If the magnetic field is judged to occur, it is judged that, when a correcting driving-pulse signal having an effective power level higher than that of an ordinary driving-pulse signal outputted for motor control is outputted to the motor, the magnetic field is generated when the storage unit is charged.

摘要： In an electronic apparatus including a generator device for generating power, a storage device for storing the generated electric energy, and a motor driven by the electric energy stored in the storage device, it is detected whether a magnetic field is generated by power generation. If it is detected that a magnetic field is generated by power generation, a correcting driving-pulse signal having an effective power larger than a normal driving-pulse signal, which is output for controlling the driving of the motor, is output to the motor. In performing this operation, a determination is made by assuming that a magnetic field is generated while the storage device is in the charging state.
