The unipolar coil motor shown in an embodiment of the present invention includes: a multiphase unipolar coil which composes of a phase made by symmetrically connecting two terminals among multi coils without a starting point or an end point, similar to a ring connection of a rotator coil in a DC motor, which is placed with certain intervals; and a drive circuit to drive the unipolar coil of each phase. The drive circuit generates two trigger signals after receiving signals from an optical sensor or a hall sensor to detect the location of stimulus. The invention provides the trigger signals to the two switches, connecting the unipolar coil to the positive pole and negative pole of the power supply for certain period to drive the motor. |
