The invention relates to a stator coil winding process which comprises the following steps of: bending a chip into a regular polygon chip, wherein pole pieces at the head and the tail of the regular polygon chip are connected and an opening of the regular polygon chip faces outwards; fixing the regular polygon chip on a coil winding machine and winding wires; and reversely bending the wound regular polygon chip into an annular iron core, wherein the chip opening of the annular iron core faces inwards. The chip of which the pole pieces are linearly arranged is selected and formed by punching, the pole pieces are I-shaped, the chip is at least formed by arranging three pole pieces, and a forked coil winding machine is selected as the coil winding machine. The stator coil winding process can not only be used for manufacturing a stator according with the requirement of a high-performance micro motor, but also can reduce the manufacturing cost of the stator and increase the production efficiency. In addition to being used for the coil winding of a micro motor stator, the process can be used for winding coils of a direct current brushless motor stator, a shaded pole motor stator or other small-size motor stators with similar structures.

The invention provides a motor stator and a method for manufacturing the motor stator. The motor stator includes: an annular stator core; a plurality of teeth protruding toward the inner peripheral side of the stator core; an insulator formed of an insulating material and attached to the plurality of teeth; a stator coil wound around each of the plurality of teeth via the insulator; a lead; and a wiring part for wiring the stator coil and the lead. The insulator has a wiring accommodating part for accommodating the wiring part.

The invention discloses a cooling water heat recycling system of a power generator stator coil. A condensation water cooling system is arranged in front of a closed cycle cooling water system, wherein the condensation water cooling system comprises a shaft seal cooler in a host machine thermodynamic system and a stator cooling water heat recycling heat exchanger which is arranged in parallel to the shaft seal cooler; and the stator cooling water heat recycling heat exchanger is connected with the shaft seal cooler in parallel through a condensation water bypass pipe. The system provided by the invention has the beneficial effects that under the condition that the cooling water temperature of the power generator stator coil is ensured, the heat of stator water is recycled to a condensation water system, not only can the thermal economical efficiency of a machine set improved, the specific coal consumption of the machine set is lowered, but also the system is good for saving energy, reducing emission and protecting the environment.
