48V to a 36V motor

tculpepper · 11-11-2013, 02:00 PM

So I was going through a recent thread and saw ScottyB mention putting 48V to a 36V motor. My question is, how long can the motor stand up to this? Will it eventually burn it up? Will it be able to handle the extra voltage? Anybody with knowledge of this or someone who has done it please chime in. I'd be interested to see the outcome of it if its mechanically safe to do. Might have to add it to my ever growing list of things to do to mine!

This upgrade is perfectly safe for your 36 volt DC motor. I have been running this mod for many years. Overvolting a DC motor is the easiest way to increase power AND speed, within reason of course. The stock controller is probably rated at 36v however and it will not tolerate 48v very long at all. Perhaps only a few microseconds. The solenoid will survive for a while, but not too long either as it is also voltage specific. Do some more reading and you will learn the proper way to increase your buggy performance.

I'm running a resistor cart right now. As funds become available, I would like to buy a conversion kit to swap over to modern technology. My next thing is an HD FR switch. Any upgrades will be able to handle swapping over to 48V. If I do swap, it will be when my current batteries take the plunge. Hopefully that will be a while. I just like planning and throwing around ideas.

One customer, having upgraded his 36v cart to my 48v system, said he's not replacing his stock motor until it starts to fail.... Talked to him recently and it has been 4 seasons and counting so far..

I myself have run 72v on a stock 36v motor and 26" tires. White I don't recommend it the motor did live. It had a tendousy to run hot so unless you were mindful of that it would eventually burn up. Running 48v is easy and won't normally poise a problem.

I took Scottyb's advice and put 48 volts to my 36 volt motor on my buil and in the 5 years that it has been running, not one lick of trouble from it. Except when I forgot to chare the batteries up, but the motor still lives strong. Thanks again scottyb.

After reading the comments, I think when my batteries die, I'll be swapping to 48V. Thanks guys!

My upgrades (including 48v) made a "night to day" difference in the performance of my buggy!

What all needs to be changed on a series cart 36v to 48v I assume controller and solenoid and f&r switch to more heavy duty one correct

The "correct" way is to upgrade the controller, solenoid (including a new diode and a new resistor), batteries, charger, f/r switch, and cables.
