Abstract
The invention discloses a coil inserting method for a stator winding of a multiphase low-voltage high-capacity direct-drive wind-driven generator, which is characterized by comprising the following steps: a, respectively arranging pay-off reels at both sides of a stator; b, respectively leading copper wires on the two pay-off reels into two coil inserting grooves, and performing coil inserting; c, when the number of coils which are led out from one pay-off reel and inserted in one coil inserting groove is half the number of the coils required to be inserted in the coil inserting groove, directly leading the copper wire of the pay-off reel into the other coil inserting groove, and using the other pay-off reel to perform subsequent coil inserting operation on the coil inserting groove; and d, after the coil inserting operation of the whole stator is finished, gathering a lead-in winding and a lead-out winding in the same groove according to the equiphase principle, and leading out. The stator winding coil inserting method realizes the double-side pay-off and one-side lead-out of a multiphase low-voltage high-capacity motor, enables the motor winding structure to be simpler, improves the coil inserting speed and ensures the coil inserting quality more reliably.
