The invention relates to a centralized assembly method of a concentric split stator and stator windings, and relates to a stator applied to a small permanent magnet synchronous motor or an AC asynchronous motor. The concentric split stator divides the hidden pole stator core into concentric main stator core and slot core parts along the radial direction. When assembling the concentrically divided stator, the stator winding components are first installed by the centralized assembly method of the stator winding, and then the slotted core components are installed, and the stator winding components are fixed by the slotted core components. In the technological process of the stator winding centralized assembly method, the stator winding is pre-prepared, and then the stator winding is assembled intensively. The method of embedding the wires into the stator slots does not require manual marking and crimping in the stator winding loose embedding process. The embedding work efficiency of the stator winding centralized assembly method is high. The continuous winding forming process of the closed-slot notch iron core punching sheet of the concentric split stator is a continuous processing process, which is beneficial to the use of mechanical equipment to improve production efficiency.
Description
Technical field [0001] The invention relates to a concentrically divided stator and a concentrated assembly method for stator windings, which relates to a stator applied to a small permanent magnet synchronous motor or an AC asynchronous motor, and in particular to a stator capable of improving the efficiency of stator winding insertion. Background technique [0002] The market share of AC asynchronous motors is relatively large. The efficiency of AC asynchronous motors is low, and permanent magnet synchronous motors have high efficiency, high power factor and significant energy-saving effects. Therefore, permanent magnet synchronous motors are gradually replacing AC asynchronous motors to become the mainstream motor. The stators of most permanent magnet synchronous motors and AC asynchronous motors use distributed stator windings. It is difficult to embed the distributed stator windings of ordinary inner rotor motors, especially for low-speed and low-power motors with a large n...
