I want to drive an industrial degaussing coil with low frequency AC. The coil needs to be about 8" ID and produce 10-15,000 Amp-Turns. The coil can be custom made, probably 1000 turns of #12 wire. I want a sine wave current in the 0.5-5 Hz range.
It has been suggested that a VFD motor control intended for a 3-phase motor could be used for this. I'd like the input to be no more than 240 VAC single phase, output a single phase of AC around 10 - 20 amps at low frequency.
Would a stock VFD be able to do this using only a single leg of its 3-phase output? Any recommendations on VFD brand or specs? This is a one-off application for testing.
