	I am in need of a Frequency controller which can change RPM of AC Motor (Rating less than 1 HP) as we want with change in frequency. e.g. If I want RPM at some time 203 RPM and then 204 RPM and then 205 RPM....Suggest me the instrument which can do this thing. __________________ Paresh B. Gujarati

	It's called a variable frequency drive, and they are readily available on the open market. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	As PWS has said, use a VFD. Note, though, that you will need your motor to be of the 3-phase induction type to work with a VFD. __________________ paulusgnome
