Because of their excellent self-starting ability, low cost, high efficiency, and great robustness and reliability, induction motors are the most widely used motor type in industry. The majority of these apps require a quick and intelligent speed control mechanism. Numerous speed control techniques can be used to give the single-phase induction motor the necessary speed control. This paper describes a PLC-based speed control and monitoring system. The PWM inverter, driver circuit, and PLC controller are all part of this system. This method uses a constant V/Hz ratio to determine the supply voltage to the induction motor based on the frequency output needed. The motor's speed, voltage, and current are among the many parameters that are tracked and displayed on the LCD panel. It lowers expenses, increases accuracy, and offers secure and visual context in contrast to other traditional techniques. Furthermore, at high speeds, PLC-based speed control becomes more efficient.
