The invention discloses a winding method of a split motor stator. The winding method comprises the following steps of: (a) taking a stator split, winding a coil on the split, wherein the number of turns of the first layer of winding is 20 firstly, secondly, the number of turns of the second layer of winding is 21, the number of turns of the third layer of winding is 20, and finally, the number of winding turns of the fourth layer is five, so that a stator block A is obtained; and (b) taking another stator split, winding a coil on the split, wherein the number of turns of a first layer of winding is 20 firstly, secondly, the number of turns of the second layer of winding is 20, the number of turns of the third layer of winding is 15, and finally, the number of winding turns of the fourth layer is 11, and a stator block B is obtained. The winding method aims to solve the problems that the number of turns of an existing stator coil is limited by the minimum part of a stator slot, so that the slot fullness rate of the stator is low, and the performance cannot be improved.
Description
technical field [0001] The invention relates to the technical field of electric motors, in particular to a winding method for a block-type electric motor stator. Background technique [0002] With the development of society, motors have been widely used in various equipment, such as pure electric drive motors, motors that drive fan blades, range-extended generators, generators driven by wind or hydraulic power, etc. These are common motors . The motor includes a stator and a rotor. The fixed part of the motor is called the stator, and the stator winding is installed on it; the rotating part is the rotor, on which a permanent magnet is installed to act as a rotating magnetic field, and then generate electromagnetic torque for energy. convert. [0003] In the prior art, in the block-type stator, the winding methods of two adjacent stator blocks are the same. After the stator blocks are assembled into a whole, the number of turns of the two sets of coils in the single slot of...
