A motor is provided and driven by two phase. The first and second control signals have a phase difference of 90 degrees and are configured to control the first and second driving units, respectively, and the first and second control signals drive the first and second coil sets, respectively. Each of the first and second poles of the permanent magnet occupies a mechanical angle of 360/2n degrees of the permanent magnet, respectively, and n is 1 or 3. The four sets of the coils of the stator are equally located on the stator, each set of the coil occupies a mechanical angle of 360/2m degrees of the stator, any two sets of the coils adjacent to each other are separated by a mechanical angle of 90−(360/2m) degrees, and m is 3 or 2, wherein m corresponds to 2 when n is 1, m corresponds to 3 when n is 3.
