please i need to build a circuit using 8051 to control both of single ac motor and 3 phase motor
i need a circuit diagram please urgently
also i need the idea to use PWM to control the frequency by 8051


thanks
 

You need design relay diagram : three phase transformer and Circuit Breaker and relay switches to control the speed of ac motor.
About PWM Modulator , I think that it's power control circuit to drive such as servo motor by a condition signal circuit toward Microprocessor or Microcontroller to generate control output.




You should design for hamless !
