I need a signal to drive a small motor that doesn't have the electrical specs and have to make some guesses and experiment to find out what it actually needs. It's actually here on ebay:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=390003257132
The seller didn't seem to understand anything about the specs other than what it says on the packet.
I'm guessing that it's single phase and by 12-20v ac they mean RMS, so the minimum voltage it would need is about 17v peak or 34v peak to peak. I have no idea what frequency signal it would need, I'm gonna try 60Hz and presumably it will rotate at roughly that rate hopefully. Do you think it needs a proper sine wave or will a rough sine wave or square wave do the trick? I've heard some motors can take an ac or dc signal.
How do I simulate a motor in SPICE as the load for an output signal? For an ac motor I think I can just substitute an inductor but have no idea roughly what size inductance.
Any good guesses appreciated.
