DESIGN AND MANUFACTURING OF FILLER WIRE REWINDING MACHINE

Electrical machines starting from motors, generators to transformer are working with the coils of conductors placed for some function. Mostly the coils are carrying the current to produce the magnetic effect. These machines can either convert the energy from electrical to mechanical or mechanical to electrical or electrical to electrical form. The proper arrangement of the conductors to be placed in minimum space with good mechanical strength can be considered as coil. These coils are practically consisting of few hundred to thousands of turns of the conductors. Rewinding of the coil is very common in case when the winding gets damaged due to the overheating. Making the coils with hand is very challenging task. Special skills are required to manually preparing the coil of conductors. It’s very critical to complete even with the manually operated machines to prepare a coil. We have designed a machine to automatically wound a coil as per the requirements of the number of turns and other size parameters. The CAD design for the machine and calculations are presented in this paper.
