A BLDC(Brushless DC) motor is provided to lower a withstand voltage performance of circuit devices by attenuating a counter electromotive force of a high voltage generated in magnetization of a fixing bobbin. A rotor has an N pole and an S pole. A stator(300) has a fixing bobbin(361). A first coil(L1) and a second coil(L2) are wound in the fixing bobbin. A first end of the first coil and a second end of the second coil are connected to a ground point of a PCB. A driving part includes a first switching device and a second switching device. The first switching device supplies a current to a second end of the first coil in order to magnetize the fixing bobbin into the N pole. The second switching device supplies a current to a first end of the second coil in order to magnetize the fixing bobbin into the S pole. |
