I’m on my 3rd ride-4-fun motor, and I keep burning them out on the hilly roads where I live. Does anyone know of any good motors that I can buy instead?
I just don’t know which manufacturers offer quality motors that I can adapt to my 2008 e4.
Yes Dave you’re correct. I think 2 things. The Torque motor is great but it must be paired with the right gear raito. I have not tried it but the 9.1 transmission is where I would start or lower if possible if you wanna go faster then 30mph. Cause the one i had was paired with a 12:35 and it took off like crazy but was done going any faster after it got to 25-30 IMO with Brushed DC motors you get speed or Torque. You don’t get both. You gotta go AC if you want that.
very hilly terrain, north county san diego. Is that costa mesa, CA that you’re in?
My engineer neighbor helped me swap out the batteries with some LiFePO batteries, have amazing range on it. We have just about a full machine shop at our disposal.
Ac motor will run 9,000 rpm making it much faster. No brushes to wear out. Ideal for high torque when coupled to low speed gears such as 2005+ Gem. 12:1
A few years ago, we develpoped a plug in kit, but only had 50 or so motors. Search 8kw ac motor.
We now have 5kw oem Gem motors, as in the 2016+ 48v Gems. They can provived 24kw peaks at 72 volts.
The problem I have is, to get geared up, I need a donor car for testing. One of us needs hands-on car to wire a new kit. I’m in Mn. Not much for Gem enthusiasts here.
Byron has kits in Costa Mesa.
Should be fine. Won’t burn out in any case. It has temperature protection. A part removed in the motors you have. A 15kw motor may fit as well. A 50hp monster.
Needs to be installed and tuned by someone with programmer,
If it was easy, everyone would be doing it.
