It has a double brush set is heavy duty and on 48v will run pretty fast with your size tires.

Question though, have you been programming the controller for the motors you are using? If not that is why you are burning up motors.

I will call monday and talk to this guy about the motor.

I am trying to balance all this stuff, seems I have to back off the long rides on hot days, it is different then running when its 80 degrees outside. I am wondering if all these things should be factored in for a golfcart. Thanks again for the replys anymore would be appreciated.

No should not have any bearing on the issue. The weight difference is not significant to cause a problem in my opinion. The real question you need to find out is if the controller was programmed properly for the motors you were running.

If you do not load the controller with the right field map to match the specific motor you will burn up the motor or the controller and in some cases both. If the field map was not load with each of the motors then that is why they are burning up. You have to do this with shunt or regen carts. Series carts you do not program the controller as they operate differently. Like I said, call Carl he will help you out and will provide you the right hex file for that motor on 48v. Tell him that Troy Morris suggested you call. I deal with him on a routine basis.

I will call him monday, added with that, I have not heard of having to set a controller to a specific motor, just have not seen that discussed here, it maybe in other threads but i guess I will hunt and see if there are any, is this done with the software fromm alltrax and a laptop.I also have 8-1 gears in the rear end

Yep it is a fact with alltrax dcx controllers. You have to set the field map to the motor and yes it has been discussed many times on these forums. Just search for field map or hex file.

Also, For reference here is the Operators Manual for the DCX it shows how you have different field mappings depending on the setting, all though this purely references stock applications. You can get a custom field mapping for the motor you run from the place you buy your motor. Carl can give you these files..

FWIW,
Fora. Forum is singular, fora is plural, like media, data, memoranda, addenda, etc.

Media are...
Data do...

Down load the software for free from Alltrax... And just pick up a cheap usb-9pin cable somewhere. I use the cheap $3 ones from ebay, work well just have to use the right driver.
