Automatic Speed Control of Motor with Over Current and Thermal Protection

open access: diamondInternational Journal of Advanced Research in Science, Communication and Technology, 2022
This paper aims to design a controller to minimize the accidents of mechanical failure of industrial generators and motors under heavy load or malfunction. The controlling parameters such as the speed of motor is done via controlling the voltage and current fed to the motor. The speed control can be possible by using PWM technique.
