This paper present the speed control of single phase Induction motor using Arduino with the controlling objectives PWM and SPWM . Induction motors are widely used Electrical Motors due to their reliability, low cost and robustness. However, Induction Motors do not inherently have the capability of variable speed of operation. Due to this reason, earlier dc Motors were applied in most of the Electrical Drives. But the recent developments in speed control methods of the Induction Motor have led to their large scale use in all Electrical Drives. Out of the several methods of speed control of an induction such as pole changing, frequency variation, variable rotor resistance, variable stator voltage, constant V/f control, slip recovery method etc., the closed loop constant V/f speed control method is most widely used. The design, analysis, and implementation of Single phase Inverter driving Induction Motor is completely carried out using Arduino.
