Abstract: This paper describes the implementation of Solar Based Controller which is designed to control the starting (inrush) current and speed of Induction Motor. The motor in starting causes I2R losses due to heavy starting (inrush) current that will overheat the engine and also may damage the motor windings. Despite the fact, many countries are currently facing the threatening problems of load shedding because of fluctuation of oil prices, faulty distribution system, ageing of equipment, and mismanagement of resources, economic & political Instability etc. This issue has been very devastating for the national economy as the industries are being adversely affected due to this severe shortfall. Accordingly, in this design, we have used solar energy to feed our system & to start (inrush) current is controlled by using Star-Delta technique. In Star-Delta technique, the first motor will run in star connection & then in the delta, and the overall process of switching is done through PLC (S7200), the line current drawn with star connection initially is decreased to one- third of starting current as compared with the windings linked directly in the delta. The speed of the motor is controlled by altering the applied frequency and voltage from the inverter to maintain different loads. The cost-effective & robust system designed was successfully experimented to implement it in industries where motors are widely operated like (Coalmines, Chemical, Textile, Cement, Sugar mills) etc.
