View Full Version : Looking into buidling an Auto-start RPC

08-31-2006, 05:21 PM
I spoke with "Al the Man" about this a while back. But I thought I would see if there is anyone in the Vancouver B.C. area that might allow me to visit their facility so I can check out their (Auto - Start) Rotary Phase Converter. Just to get a visual as to how everything is wired in.

And if possible where to find a good, least expensive 20 HP Motor and electrical component supplier for run capacitors, push buttons, timers, timer relays etc.

Any assistance would be greatly appreciated.

That was me, I am having trouble getting my password reset.

Look for good used 3 phase motors at your motor supplier/rewind shops, if you are looking for 220 they are usually cheaper.
If you intend buying timers relays etc, look at using a smart relay like Siemens Logo, they are also made by Omron, Idec and others, (identical).
Cheap on ebay.
The will allow you to program logic with less hardware.

For a self starting rotary, look at US4158225, Claude M. Hertz, inventor, assigned to Ronk Electrical Industries. The other patents by this inventor and assignee are all worth looking at as well.
