Can anyone guide me through making an Inverter to control the speed of a 1HP single (or 3) phase induction motor?
I sometimes come across induction motors at a local tip that work but are of fixed speed, and wish I could use them better. I have one at the moment which I plan to build into a humidity dependent (with user override for occasional purge venting) ventilation system.
So I want to be able to control the speed of an induction motor which currently runs at a fixed speed, off single phase 240volts. I wonder if anyone has experience they might share in putting together an inverter capable of doing this?
