Abstract : An induction or asynchronous motor is an AC electric motor in which the electric current in the rotor is needed to produce torque is induced by electromagnetic induction from the magnetic field of the stator winding. The induction machine is used in a wide variety of applications as a means of converting electric power to mechanical work. It is without doubt the workhorse of the electric power industry. As we know that induction motor is nothing but generalized rotating transformer. This same concept can be used to implement the motor as welding transformer. Welding transformer required low voltage and high current for joining of two metal parts by electrical arc welding. So some modification can be done in the stator winding of induction motor which may cause induction motor act as welding transformer. Also the same motor can be implemented for operating on the single phase as well as three phase supply. The running and starting winding of the single phase operation are placed in the same slots that are used for the three phase operation. So at a time anyone of them can be used to supply or produce excitation in order to employ rotation of rotor. In this paper the construction, winding designing scheme for stator and results of redesigned machine are presented. © 2016 IEEE.
