Title:
METHOD FOR MANUFACTURING STATOR COIL, STATOR COIL, AND ROTARY MACHINE
Document Type and Number:
WIPO Patent Application WO/2024/052961
Kind Code:
A1
Abstract:
This method for manufacturing a stator coil comprises: a first step for winding a mica tape (7) on a coil conductor (5); a second step for winding a prepreg tape (9) on the coil conductor (5) on which the mica tape (7) has been wound; a third step for winding a thermal shrinkage tape on the outer circumference of the coil conductor (5) on which the mica tape (7) and the prepreg tape (9) have been wound; a fourth step for heating the coil conductor (5) and curing a resin included in the prepreg tape while compressing the mica tape (7) and the prepreg tape (9) by a shrinking force of the thermal shrinkage tape (8); a fifth step for removing the thermal shrinkage tape (8) and impregnating the mica tape (7) with a liquid resin (10); and a sixth step for heating the coil conductor (5) and curing the liquid resin (10). By using said method, a stator coil having excellent electricity resistance and heat dissipation ability can be provided.
