Changing Motor

blazer crazy

Well, after a week of trying to find out why cart was running poorly, problem solved. There was a loose wire (green) that had been previously spliced. Go figure! But thanks for all of the help provided it was priceless to say the least.
Now that I know more than I ever dreamed I would about elec carts, I would like to change the motor to a torque motor. The motor I have is fine (2006 D/S 48 volt), but I need more torque.

My questions are
1. Is it hard to replace motor?
2. Do I have to change cables?
3. Do I have to change controller?
4. Is there a market to sell the motor I have and how much is it worth?

Thanks for all your help! Tommy

Tommy,

glad you got it fixed. Call the guys T plum quick and tell them what you want and they will build it for you. They will have you send in your motor to be upgraded. If your wires are stock 2006 then it is time to replace anyway. As far as a new controler, solenoid, HD f/r, ect, it depends how much torque you want! Call plum quick!

Tommy, glad you got that fixed!

I would go with a PQ motor which will give you a bit more torque and a lot more high speed. This will cost you $225. If you still feel you want more torque, then you can go with an Alltrax 400 (that would really give you a kick in the butt). Goes for around $400.

1. Simple to replace motor, just make sure you switch controller to tow then take off - and + cables that lead to controller and solenoid.

2. Definitely should change cables with new motor especially if you add a bigger controller. The wider the cable the happier the motor. 4 or 2 ga would be fine w/ 400amp controller (500amp controller definitely 2ga cables). Preferably welding cables. $100+/-

3. If you get the PQ motor, no, you don't have to change controller. However, if you are not happy with the torque the new PQ provides, then you should consider getting a bigger controller. Some motors like "the Beast" do require to change controller.

4. If you send your motor to PQ, you'll get back a high torque motor for $225. If you buy a new upgraded motor, you'll pay around $700. Your used motor is probably worth $100. Your call!

I would start by changing the cables to 4ga, available on ebay for less than $40 then the controller to a 400-500 amp unit. If that does not do the job, a rebuild from someone like PQ would be next.

BLAZER CRAZY-- Remember to replace the Motor Drive Spline Bumper Part #102235201 and use ( complete tube of lub ) Part #102243403. If you have ever had a motor shaft frozen to differential input shaft OR motor knocking like a U Joint was out, you will know why I recommend replacement while every thing is apart?

$400+ = a lot of torque little to no top speed increase with stock motor

$225 = lots of top speed, some torque increase

both = best of both worlds

If you go 500 amp, go 2 ga cables

How about over heating a aftermarket motor with like stop and go, killing your batteries faster because it requires more since the motor will pull more. These are the things I have been told and that is one of my reason for not doing anything yet.

No overheating issues with stop and go with aftermarket motor (in my case PQ motor). Actually with my new motor and cable set up. Motor runs cool to the touch. Much color then stock set up. Its when you add an after market controller that you can get into heat up situations when running at constant slow speeds. Depending on your set up. Thats why Im going with a 500 vs 400 altrax. 500 offers a bigger heat sink. Also, you can program it down to 80% capacity which will bring it down to 400amps vs getting a 400alltrax and running at 100% full capacity. Their is a member here who has a 500alltrax with motor set up and can run under 5mph forever without any overheating issues.
