PURPOSE:To prevent an insulating spool from getting out of position in the direction of the inner diameter, by providing a spool-fixing groove into which the tip of the collar section of the insulating spool is to be inserted on a stator core. CONSTITUTION:An insulating spool 3 wound up with a coil 2 is provided with a collar section 4 along the inner peripheral face of the slot of a stator core 1. In the mean-time, spool-fixing grooves 5 with fitted collar sections 4 are formed on the both sides of salient sections 7 provided inside penetrating holes 6 for penetrating bolts for fixing the core. As the result, the dimension of the inner diameter of the insulating spool 3 can be prevented from being inferior, and the spool 3 can be prevented from butting against a rotor. |
