Can I run the D&D ES-31C at 48v and do anyone know what the HP would be or must I run it at 72 min voltage.
I at this time only have a 48v 400 amp controllor.
The motor and car is on firstontop com click on the VW BUG.
I am going to get a 120v unit but it will take me some time.
I want to start the wiring of the car and up grade when I get the better controller.

I have a 31B. Do you know the specs for the C? I expect the reason for the low end of the rating would be for cooling. If you're running at under 72V it won't be spinning fast enough to self cool.

I think you'd be fine running at the lower voltage (aside from being extra sluggy) if you added a forced air blower for the motor.

The ES=31C info is on this site http://www.cloudelectric.com/product-p/mo-es-31c.htm It can go up to 144vdc

I will run this motor at 72v and up,I will not go 48v on this one.

I got a lead on a 1221b so I can now run the vw at 120vdc and 60mph I can be happy with that in a VW bug.

You will like that. Should do a bit better than 60. Just be easy because of the smaller motor but you should be fine. Smaller motors can run a bit higher rpm too.

I am air cooling the motor and most of the time this is going to be a display car.
