i'm working on speed control of three phase induction motor, requiring constant ratio of frequency to voltage, without microcontroller implementation.pls, i need a circuit diagram, no matter how complex!
Then you should immediately begin drawing up said schematic!!
We will gladly assist you with specific problems as they arise.
Also, if this is a school assignment (the "without microcontroller" requirement usually indicates a school assignment) we will be happy to move this thread into the more appropriate forum. Just let us know.
