Troll1987 Posted April 4, 2010 Report Share Posted April 4, 2010 The detail of project is below:Design a circuit for the following function:Aim:CNC motor speed controllerFunctions:1.Closed loop control system (maintain the speed)2.Set point speed control (Setting output power)3.Actual Speed readout to LCD or LED ( Use either diode or magnetic sensor)4.DC motor either linear or pwm controlThis curcuit should be using analog circuit which mean without PLC or other computer control unit.I know the pwm control circuit and I have trouble with using the inverting amplifier or noninverting amplifier for the close loop system and the the sensor for the speed readout and the circuit to LCD or LED. Is there have any suggestion? Quote Link to comment Share on other sites More sharing options...
