PROBLEM TO BE SOLVED: To provide a drive device using a motor that can maintain the speed of a motor constant and at the same time further save power. SOLUTION: A device has a motor 30 for switching the number of the coil windings of coils 32-34, where a drive current flows to at least 2 from among, transistors 35-44 for switching the number of coil windings of the coils 32-34 of the motor 30 and driving the motor 30, a voltage detection part 51 for detecting the voltage of a power supply part for driving the motor 30, a temperature detection part 52 for detecting the environment temperature where the motor 30 is provided, and a motor control part 53 for varying the number of coil windings of the coils 32-34, based on the voltage and the temperature being detected by the voltage detection part 51 and the temperature detection part 52, respectively, and for controlling the transistors 35-44 so that a drive current can flow in the coils 32-34. |
