Default FSIP Speed Motor - Max RPM

Hey y’all,

I have a 2017 EZGO w/ a Navitas TSX 440a controller and an FSIP Speed motor. The Cart Is lifted and has 23” tires. The other day I was horsing around on it and playing with the settings and I got it up to 38 mph going down a hill, it wasn’t until afterward that I even thought that might be too fast for the motor.

I called FSIP and their tech support couldn’t tell me anything regarding max speeds. I was hoping someone out here might have a little more insight.

Thanks!

assuming a gear ratio of 12:44, 23" diameter tires and 38mph = ~7000rpm.

Yeah, that’s the part that I’m concerned about but can’t get info on. How fast can this thing turn before damaging the motor?

I would recommend keeping the RPM's max at 6,000. 38 is flat out hauling!!!! I have the same comboi on my Precedent. Love it

Just ask JohnnieB what happens when you over-rev a motor going downhill. They go BOOM! Fasten your seat belt because you're coming to an abrupt stop!

6k is the recommended max motor rpm for anything that is not banded. The Admiral motors have a small banding on them. We run them at 6200. Freewheeling down hills may be a very expensive and possibly dangerous thrill.
Catastrophic motor failure can result in a sudden rear end lock up at speed.

What other motors do you know that are "banded". I definitely experienced the catastrophic motor failure this week. Need a motor that can handle the speeds but also add some more torque for my set up. Mainly flat terrain with one hill, 28" tires and before this event I was able to cruise at 30mph and max speed ive hit was 33. Clocked from my garmin, i was running a 600amp controller and stock motor.

I think any motor manufacturer can band a motor. Try EMP, they make custom motors to your requirements and do banding on high rpm motors. Drive safe!
