AC 220V Single Phase Speed Controller Arduino
I have a 220V AC single phase 2 hp motor. I am looking for a speed controller design using arduino. I have seen different things around but never anything matching this exactly?
What type of sensing do you want to do . You could current sense or measure rpm with either a hall sensor or an encoder?
motors needed for shredders or similar torque hungry devices are typically 3 phase, a standard VFD (100 – 150euro, only) provides you all you need: endless functions, inputs and outputs.
an Arduino is only really useful to deal with the VFD itself: regulate speed, direction and handle over torque or stall. with better VFDs you can also handle the shredder via Modbus, a more standardized way to deal with this sort of devices 🙂
