Energy efficiency of Induction motor (IM) is essential in the current scenario due to the reasons such as energy conservation and economic saving. In this project, the implementation of the safe speed control of IM is done. The Programmable Logic Controller (PLC) monitors the speed and trips the motor under safety requirements. PLC is used to control three phase IM with the Variable Frequency Drive (VFD). The availability of drive data and software helps to manipulate and analyze process the information. The Human Machine Interface (HMI) is used for the visual monitoring and control of the induction motor. The PLC based control platform makes system to be communicated to other devices on network and makes the system more flexible for its operation and control. The results shows that, the speed of the induction motor varies linearly with the change in frequency in HMI and the motor trips if there is any human interference within 10 cm operating range of IM.
