Hi need advise 馃 I have a old forklift motor I need a Brushed DC speed controller for , a 45v RPM 1900 RTG 1/4HR winding COMP Electric motor, using 4x110AH 12v lead acid batteries ,

Also there's a picture of a speed controller I already have but can't get it to work for some reason

Would be grateful for any advice to point me in the right direction 馃憤

So the Nissan Micra is a tiny car. Do you have the motor connected directly to the transmission? I鈥檓 assuming front wheel drive here. Kelly Controller has some decent offers you could use as does Curtis. Not sure anyone is supporting or even building Series Motor Controllers anymore. Hunt for a decent used one.
