Abstract:
An initial position determination process and a rotation driving process are both attained. A motor includes a rotor having a permanent magnet with a plurality of magnetic poles and a stator having coils with a plurality of phases. A voltage signal generation part generates a voltage signal corresponding to an electric current flowing through each of the coils with the phases of the stator. A filter part includes a first filter and a second filter. The voltage signal is inputted to a comparator through the filter part. A control part controls such that the first filter whose filter constant is larger is selected when performing the initial position determination process of the rotor and the second filter whose filter constant is smaller is selected when performing the rotation driving process.

Claim (Index 5):
The motor driving device according to  claim 3 , wherein the control part determines an initial position of the rotor when the difference in the voltage rise time is equal to or greater than the threshold time difference.
