Technical Examples

A motor driving device includes a motor having three-phase driving coils, a power feeder for powering the coils, and a power feeding controller for controlling a power feeding method. The controller controls electrical potentials of the coils in a period of applying a voltage to the coils to be a power-supply voltage potential or the grounding potential by turning on or off transistors in the power feeder during a first feeding period which starts from a motor halt status and ends when the motor is driven at a given speed. During a second feeding period where the motor is driven at a speed over the given speed, the controller controls the potential such that the coils are opened by turning off the transistors or the potential becomes the power-supply voltage potential. This structure allows the motor driving device to drive the motor at a lower noise with less vibrations.
