Firstly seasons greetings to all forum members,
I am trying to determine the best way to control a universal motor without losing too much torque?
As it is a universal motor I wondered if there would be any benefit in rectifying the supply and working only with DC? I can't find any info on this but would it be better doing this and then using PWM to control the speed.
Other than that I have seen a number of articles on using SCRs and indeed I have some that would be suitable but these designs all seem to contain a DIAC as well and that is something I am lacking in.
Anyway I am open to ideas and suggestions, maybe using a PIC micro would be good?
Thanks for looking Al
