摘要：
A method for driving a brushless motor including a first coil and a second coil for two phases but does not include a coil for one of three phases. A three-phase inverter circuit is connected to the first coil and the second coil. Currents having a phase difference corresponding to an electrical angle of 60 degrees are applied to the first coil and the second coil to generate a circular rotating magnetic field.
