air compressor magnetic starter/relay single phase

   / air compressor magnetic starter/relay single phase #51  
Update. Measured again, 240v current draw just turning alternator is 5 amps, with field current applied to alternator 11 amps, welding at 110 amps, 27 amps. Would be under 5 amps not running anything.

All my 3 phase is run via a rotary converter made from an old 3 phase motor...

No pony motor... simply give wind rope around the idler and give it a pull as I power it...

25 years and it has been working...

Keeping it simple has advantages. Not much can go wrong.

Good luck to the OP with his air compressor. We kind of got off topic.
