I'm cooking up a plan to run my ac compressor off of an electric motor so that I can relocate it to where the old air filter/battery used to be. I'm wondering how much hp the thing needs to be rated at to spin the a/c.? I figure between .5hp and 1.5hp apinning at about 1000rpm, does this sound right?

 

your a/c compressor cannot compress the refridgerant enough with an electric motor wont spin enough but doesnt hurt to try keep us informed

 

what? they make all types of electric motors with different hp rating and speeds, I know one of them will spin the a/c fast enough, especially if it's connected directly to the shaft on the compressor. The fact that the a/c works while the car is idling meands that it obviously doesn't need to be spun very fast in order to work...

 

that's a very good pint. why don't you use a torq wrench attached to the ac compressor pully and see how much force is needed to turn the compressor over and make some calculations. i think a 1/2hp elctric motor will be more than enough to run the a/c compressor. you're gonna need a more powerful alternator though. i'd just cut amd modify whatever is in the way of the orinal a/c comp in it's original position. and fabricate a manifold and downpipe combo so i could keep the a/c. that would be easier and less expensive i think.

 

what do you mean hp for a/c? like how much hp you would get from removing a/c? or hp for a motor to drive the a/c system? if your talking about removing a/c to see power gains of some sort that would be kinda stupid. a/c is not always only works off the belt when u turn it on.

 

jebus! READ! he wants to spin the a/c compressor using a elec motor. the BELT IS ALWAYS MOVING, but the compressor clutch is on/off (contrlled by the driver, button).

 

LOL i was gonner say the same thing

 

you could also play around w/ diffrent size pulleys in case your elec. motor isnt strong enough or doesnt spin it fast enough.
