Speed difference

[BRainey]

Why does a 36 volt motor go faster on 48 volt system than a 48 volt motor on its own system?

[Sir Nuke]

because you are putting more voltage to it then it was originally designed for.

[JohnnieB]

If you ran a 48V motor at 64V, you'd get about the same results as running a 36V motor at 48V.

Of course, the solenoid and controller would have to run at 64V also.

-------------
Along those same lines, I wonder if anybody has tried retrofitting a 36V DC motor in a later model 48V DC system to get more speed.

[BRainey]

If I ran at 64 volts, is there a way to override the over voltage setting in my DCX 500amp controller? I believe it only goes up to 60 volts.

I proposed this years ...... ago and a few BGW members have taken advantage of my theory with good results.

Not that I know of. Contact Alltrax and ask.

They have AXE (Series) controllers that work up to 72V, but I don't see any of their SepEx controllers that will go that high, but other controller manufacturers may have them.

The components in this control are not capable of operation in excess of 60v. Connection to a source greater than 60v may cause immediate failure. Like Johnnie says they make 72v models which can use 64v. Let us know when you find a 64v charger

Thanks for that info.
It just occurred to me while I was typing me earlier post. Glad to know it works.

Did the just switch to a stock 36V PDS motor and keep the stock 48V Curtis 1206HB or did they use aftermarket motors and controllers?
