The invention discloses a motor winding structure and a winding method thereof. The first pole arm of each phase pole arm group of the motor is wound with a first inner winding coil, a first middle winding coil and a first outer winding coil; Winding the second inner winding coil, the second middle winding coil and the second outer winding coil on the second pole arm; winding the third inner winding coil, the third middle winding coil and the third outer winding coil on the third pole arm; series connection The third inner winding coil, the first middle winding coil and the second outer winding coil form a first series coil group; the third middle winding coil, the first outer winding coil and the second inner winding coil are connected in series to form a second series The coil group; the third outer winding coil, the first inner winding coil and the second middle winding coil are connected in series to form a third series coil group; the first series coil group, the second series coil group and the third series coil group are connected in parallel. The invention can solve the problems that the existing mechanical winding method has high copper loss and the product performance cannot be improved.
Description
technical field [0001] The invention relates to a motor winding structure and its winding method, especially to a winding structure in which the inner, middle and outer winding coils on three pole arms are connected in series, and then connected in parallel with another group of series coils. method. Background technique [0002] With the development of the times and the advancement of science and technology, people's living standards have generally improved. Among them, the motor has played a very important role in people's lives. Specifically, the stator is an indispensable mechanism in the motor. The motor is mainly The rotation is caused by the induced current generated by the mutual induction between the stator and the rotor. In the manufacture of the stator, the winding is mainly formed by winding the wire on the pole arm of the stator ring to form a multi-layer induction on the pole arm. coil. [0003] However, in the stator made by the traditional old mechanical wi...
