PURPOSE:To lower coil ends and improve cooling property, by a method wherein a coil member is divided into two ring-like units, wherein the one side is inverted, and wherein the both units of the recess section and the projecting section are confronted with each other and are put together to be stator coils. CONSTITUTION:A coil member 20 is divided into two units to be divided coils 20a and 20b, and the divided coil 20b among the coils is inverted at an angle of 180 deg.. After that, the recess section and the projecting section of the inverted divided coil 20b and the other divided coil 20a are confronted with each other and are put together to form stator coils 40. Then, the stator coils 40 are formed flat in the circumferential direction uneven so as to be inserted into the respective slots 21 of a stator core 2, and after that, the coils 40 are inserted into the respective slots 21 of the stator core 2. In this manner, even if the occupation rate of the stator coils 40 in the slots 21 is high, the coils 40 can be inserted, and low coil ends can be obtained, and cooling property is improved. |
