Abstract: Induction motors are widely used in industries for obtaining motive power, as it has many practical advantages over other types of electrical motors. Induction motor characteristics are suited for Variable Speed Drive which is mostly preferred over Constant Speed Drive. This study implements speed control of two three-phase induction motors are controlled on the basis of FPGA drives. The SVPWM is criticized on a single FPGA chip to provide necessary switching pulses for inverter blocks .The adjustable speed is worked out bymanaging voltage and frequency using FPGA. The experimental setup is built with Xilinx Spartan-6 FPGA family. Experimental results are evidence for that FPGA-based solution for multi induction motor drives are operation flexibility, lower cost and good in performance.
