PROBLEM TO BE SOLVED: To provide a motor driving device enabling to freely select an angle formed by the rotary center of a rotor and two magnetosensitive poles. SOLUTION: A controller of the motor driving device switches the electrifying direction of a first coil 4a in response to a first lead angle signal to be obtained from a first magnetic pole detecting signal and a second magnetic pole detecting signal. Also, the controller switches the electrifying direction of a second coil 4b in response to a second lead angle signal to be obtained from the first magnetic pole detecting signal and the second magnetic pole detecting signal.
