My truck has a manual transmission and no clutch. I was think of using a Masterflux or other EV/Hybrid compressor to turn it but the MF is over two grand I've read. EV/Hybrid units are too high of a voltage I suspect but haven't looked into it much yet. Just kicking around ideas now and wondering what you guys are doing?

How are you driving yours if it's not on the main motor? My pack operates around 160V and was thinking of a 2 or 3HP 180V PM motor switched on by some sort of relay would work fine, preferrably solid state but I'm afraid the EMF might blow it when it shuts down. I know this isn't optimal but it may be the most affordable yet reliably workable system if I can keep the thing from blowing up!

I'd rather have a PWM controller but haven't seen anything less than Curtis motor controllers that will operate at pack voltage.

If you are getting the Soliton 1, you might be able to go with a belt driven stock compressor. I know you don't have a clutch but if you are stuck in traffic, you might be able to get the soliton to idle the motor while you are in neutral. That is if your transmission puts out a neutral signal.

I don't know if manual transmissions typically do that but it might be worth looking into.

I dont know how that would work, but then again, I have never tried to put a car in gear on an idle, that I can remember....lol

There just doesn't seem to be anything short of an EV controller to do the trick that I've seen. I'm sure it could be built but that would seem to be a royal PIA. But I've built stuff like that before, just don't want to spend the time.

What are you looking for? . . an inexpensive PWM control that will run from your pack voltage?

Yes! All I've found are EV controls or controllers input rated at <100V.

One of my suppliers called me a minute ago and I asked him if he had a 2 or 3HP motor. Likely but that large it may not be a PM but a shunt wound to which I'd have to make a field controller, field loss circuit etc. You know with a shunt wound motor if you lose the field the thing could spin up and self destruct!
