摘要：
A controller for a motor driving apparatus switches a direction of electricity flowing through a first coil according to a first lead angle signal obtained based on a first magnetic pole detecting signal and a second magnetic pole detecting signal. The controller switches a direction of electricity flowing through a second coil according to a second lead angle signal obtained based on the first magnetic pole detecting signal and the second magnetic pole detecting signal. Thus, a motor driving apparatus can be configured such that the angle of the rotation center of the rotor with respect to two magnetically sensitive poles can freely be selected.
