36V motor on 72V??
What happends if you apply 72V to the stock 36V motor?
RPM should be safe, I saw the 168V cart on Youtube I would go into debt for somthing like that. NO NO EZGO has currently got me sold on a DD6531 and a DCX500 on 48 I have a 36V with Coils now, so I have to change everything. I will be going this rought unless sombody talks me into somthing better Would a 72V be better?? BTW: I took a ride in a AC/DC. I was NOT impressed. 27mph for $4000 If I spend $4000 this thing better launch |

Just as a follow up, it's a D&D ES6551, I think. That may be an old-style Yamaha and Club Car motor though. I'm sure they have the same motor with mounts for an E-Z-GO Dana differential though. That may be what you're speaking of.

Re: 36V motor on 72V??
It will work but how long it will work is another question. Muaythia has been running 72 volts for quite a while on his 36 volt motor. He doesn't abuse it but when he needs to 'go' its "GOES". Keeping the PRMs down or at least not very long at high rpm's IMO is the key to a long(er) life with higher voltage on low (36 volt) motors.
I wouldn't buy a DCX controller simply because the motors cost more to upgrade. Maybe a Series style Alltrax 72 volt controller with a good motor like a beast motor. A beast motor on 72 volts will snap your neck and last longer on 72 volts. Only because that motor is built for low speed torque. I think it runs 2100 or so on 36 volts....72 volts will give you around 4200. 4200 rpm's keeps the rpm limits in check. Converting to a PB-6 throttle is fairly staright forward if you can fabricate a little. |

Re: 36V motor on 72V??
I know any GE motor is built to work up to 96v & 10,000 RPM... I just asked my supplier today about them..

Re: 36V motor on 72V??
That 168 volt cart of Nates has a specially built motor. Its designed to run on higher voltages.
Swapping in an alltrax or other controller is easy. You could buy a newer variable resistor v-glide assembly which bolts in the same as a resistor coil carts v-glide. Only thing about that is the throttle isn't as smooth as a PB-6. If you opt for 72 volts keep in mind you need a 72 volt solenoid or just buy a czonka relay. Be sure and look at all your options out there. |

Re: 36V motor on 72V??
that is what they are designed to do... so they should be able to hold that?
I was asking because I'm toying around with the idea of making a 72v cart, and wanted to see what motor to use. I don't do most of the ordering, but when I talk to them again, I'll bring it up for you... |

Re: 36V motor on 72V??
From what I understand they are overbuilt, So the chance of them blowing up on 36 or 48v is slim to none at all... I would imagine as with all things, the more RPM, and more voltage the more chance of grenading.... I'll talk to them...
(My supplier gets plenty of money from us, and have for the last 20 years, they won't blow smoke) |

The question was 36 volt motors on 72 volts not 96@10,000. Yes 72 will hold up if not abused, even more for that matter. We run 108 volts but dont push our luck. |
