Four-pole gullet-free motor adopting 12-coil self-supporting winding

The invention relates to a four-pole gullet-free motor adopting a 12-coil self-supporting winding. The motor comprises a stator casing, a stator core, a rotor permanent magnet, a front bearing, a rear bearing, the winding, a PCB and a rotating shaft; the PCB is used for leading out the winding, the winding is fixed on the stator core and is connected with the PCB, the stator core is mounted on the stator casing, the rotor permanent magnet is sleeved inside the stator iron core, the rotating shaft penetrates into the front bearing, the rear bearing and the rotor permanent magnet, the number of poles of the rotor permanent magnet is four, and the winding is a 12-coil self-supporting winding. Compared with the prior art, the four-pole gullet-free motor has the advantages that the capability of generating counter electromotive force by the winding can be more effectively improved, and then the performance of the motor is improved. 本发明涉及一种采用12线圈自承式绕组的4极无齿槽电机，包括定子机壳、定子铁芯、转子永磁体、前后轴承、绕组、用于引出绕组的PCB板和转轴，所述的绕组固定在定子铁芯上并与
