This paper aims at the fabrication of five phase induction drive for laboratory purpose from three phase to five phase transformer connection. Here, five phase drive is proposed rather than conventional three phase drive because by increasing the number of phases torque ripples are reduced hence amplitude of the current is reduced without increasing the voltage per phase therefore it increases the reliability of the system. In five phase drive, failure of one phase, the performance does not degrade to that extent in the three phase drive. Considering these advantages than conventional three phase drive fabricated the induction motor. To facilitate five phase supply, obtained from the transformer setup it takes three phase supply as input and five phase supply as obtained as an output by properly connecting the secondary windings of the transformer. Experimental Results are analyzed both three phase to five phase transformer connection scheme and five phase induction motor drive.
