SERIES MOTOR

PURPOSE:To enable coil winding having different coil pitches freely by mounting a mechanism interlocking reciprocating and swinging motors so that the locus of the nozzle of the nose of a spindle directly wound to a stator takes an oval. CONSTITUTION:A belt 6 is stretched between a pulley 5 set up to the shaft 4 of the main motor 3 and a crank 2 for reciprocating the spindle 1, and the crank is driven by means of the main motor 3. The oscillating motor 14 is coupled with the spindle 1 through a pulley 15 and a belt 16, and the nozzle 18 is fitted at the nose of the spindle 1. Results obtained through arithmetical operation in a pulse controller are inputted to the controller of the swinging motor 14 which is interlocked with the main motor. Accordingly, the locus of the nozzle 18 can be changed arbitrarily through the mutual motion of the main motor 3 and the swinging motor 14, the coils having different coil pitches can freely be wound, and the speed of winding can be increased.
