20150303780 | STATOR HAVING THREE-LINE CONNECTION STRUCTURE, BLDC MOTOR USING SAME, AND DRIVING METHOD THEREFOR - Provided are a stator having a three-coil wiring structure, a BLDC motor using the same, and a driving method thereof, in which coils are wound by using a three-coil wiring method, to thus minimize a ratio between slots and poles, and to thereby reduce cogging noise, and a gap between cores is set small, to thus increase an effective area between a magnet and a core and to thereby reduce leakage magnetic flux. The BLDC motor includes: a stator having a plurality of split cores that are disposed between an inner rotor and an outer rotor, and on which coils of three phases are connected and wound in a three-phase drive method, in which the plurality of split cores include a number of core groups in which the coils of the respective phases are wound on three consecutive split cores in sequence of a forward direction, a reverse direction, and a forward direction, and the three consecutive split cores generate magnetic flux in opposite directions to each other. | 10-22-2015 |
