Brushed Unite motor 48v at 24 v

[stocaz]

HI dear friends of Endless sphere
i'm going to use a 48v 450 w brushed motor like this http://farm8.staticflickr.com/7237/7312953700_124a4c44be_n.jpg
with a 24v 250w controller
motor will work properly?less heat? less noise? any problem?
or doesn't change anything like it would be a 250w motor?
thanks

It will be very slow.

Ja, rpm is proportional to voltage.

..much slower than a normal 250w 24v motor?
thank you
