This book is about single and split phase induction motor controller. The features controlled are switching, direction and speed of the motor through remote location (PC) and local location (keypad) while measuring and display the RPM of the motor on a MONITOR SCREEN and LCD. The industry mostly uses DC motor due to their easy control but they have their disadvantages of high maintenance cost and inability to work in corrosive or explosive environment. The control of an AC motor are usually complex and require complex algorithms to be implemented but AC motors are light, inexpensive and have lower maintenance cost. This project enables us to control and monitor many AC motors with a simple control circuit. The system consists of main blocks: Speed Sensors, Cycloconverters, On and Off control, Direction control, Microcontroller, PC programming, PC interface.
