Control a single phase AC Motor using arduno

tejaswivarma

Hi

              I wan to control a single phase motor using arduino (PWM).  can any one sujest me how to do that.

 

                                            Thank you in advance

                                                                                                                              have a nice day

    Hi,

     

    the complexity of your project depends very much on what exactly you want to control. If it's only about switching the motor on and off you can take e. g. a solid state relay that is capable of switching inductive loads. If you want to make a speed control then it depends on what kind of motor you have.

     

    Suppose you have a motor with a collector and brushes like the ones e. g. in the power drills then you can control the speed with variation of the supply voltage. These motors are series-characteristic motors that run also on DC.

     

    If you have a real AC motor without collector but with a capacitor and a second winding to start it then you need a frequency converter to variate both the voltage and the frequency.
