<P>PROBLEM TO BE SOLVED: To insert a trapezoid coil with a reduced winding twist angle into a tooth portion of a laminated steel plate stator core. <P>SOLUTION: In a manufacturing apparatus of a motor stator having a stator core 30 where a plurality of recessed slots 32 and a plurality of tapered projecting teeth 31 are formed on an inner periphery and a plurality of trapezoid coils 10 disposed in the slots 32 where rectangular conductors with rectangular cross-sections are bent and concentrically wound in a trapezoid, a coil shape regulation member can regulate the first trapezoid coil 10A in a wound and twisted state to insert the first trapezoid coil 10A into the tooth 31A while preventing the first trapezoid coil 10A from being wound and twisted. <P>COPYRIGHT: (C)2013,JPO&INPIT |
