Re: Building tractors from golf cart parts...
Ok... Question time... I'm gathering parts to build my second tractor. This time I'm going to use a controller and a standard tranny. One of my questions is... can I test my junkyard controller and motor just using a 36 volt battery charger? I have a winter time shop set up in the basement of my home (it's warm there) and I don't have any batteries there. So everything now sat up on my work bench ready to be tested. Next question. The golf cart (36v) that I got my parts from was missing the motor. I found a 36v motor out of a forklift that I want to use. The question is can a motor be to large for a controller ? Can I burn out the controller if the motor is to large ? This is my mess on the bench right now...

Re: Building tractors from golf cart parts...
You might be able to pick up some ideas with respect to motor and controller sizing from the attached Alltrax documents.
These documents and others can be found at: https://alltraxinc.com/documentation/ What is the size of tractor for the build you are planning? |

Re: Building tractors from golf cart parts...
If by size you mean amperage draw then yes, the motor can pull too much amperage for the controller to manage. By manage I mean that everything in the drive system must be matched up (engineered) correctly. If the motor is drawing more amperage than the controller can comfortably pass it will get too hot and the heat will cause failure, then same holds true for the other components in the system. If you get out of balance then something will fail.
And generally, no a battery charger will not run the system. |

Re: Building tractors from golf cart parts...
I see there are a number of articles on the internet about using forklift motors in electric vehicles ... in the few articles that I have reviewed, it is not always a straight forward process ... but as ScottyB indicates, matching up the right size equipment seems to be right approach.
Here is an interesting article about using a forklift motor in an EV and some reasons why this person did NOT use a forklift controller in their build. https://forkenswift.com/used-forklif...ectric-car.htm |
