Default Seeking AMD 7144 (GG1-4002) Specs

Have upgraded my CC Precedent '11 with the AMD 7144 motor, paired with one of the new Alltrax XCT controllers. I'm in search of the full specs for the 7144 motor, so that I ensure the controller config does not exceed the capabilities of the motor. (Most notably, the max RPM rating). I've searched the various AMD reseller websites, the AMD/Nidec site itself, tried contacting AMD, and as of yet had no luck with tracking down the full specs of this motor.
Has anyone here who has the 7144 motor tracked down the specs that they could post ?
Anyone who has this motor paired with an XCT controller - what have you set the max RPM setting to ?
I've cranked it up to around 6,000 rpm and I'm getting 28-29mph on a 6" lifted cart with 23" wheels, but not sure if that RPM setting is exceeding the capabilities of the motor.

Good luck. I tried contacting them to get the spec on the 7114 motor. After a couple of calls and a email not returned I decided to spend my money elsewhere.

I so have the 7144 motor with an alltrax xct500. Can't find any specs either. I've got max rpm set to 6500 and I'm only getting 27mph but I do have 21" tires. If I take off on a steep incline I get a strange noise from the motor. Are you experiencing that as well?

I googled around and found this description:
Speed & Torque motor for Club Car IQ & i2 Excel.Specifications:48 volt 7HP @5106 RPM10 Spline4 gauge cables required. High amperage solenoid required
Any motor that runs out at 20 mph and up is labeled a speed motor but when you look at this motor it produces a lot of torque at 5100 RPM. I would be hesitant to run it at 6500 for long.

The distributor provided the attached... which obviously doesn't translate to max rpm rating...and not quite sure how to interpret the field/armature curve as far as the corresponding settings in the XCT. Will keep searching for specs.

As for motor noise - not experiencing that with mine, although I don't have many steep inclines - pretty flat here, biggest incline is probably only 15 degrees.

The motor noise under heavy acceleration is probably just brush arc and stops when very high amperage draw recedes.

Sounds right. It only does it for a second or two when I start from a stop up a large incline.

Jcarney619 sorry, didn't mean to hijack

At 5100 RPM's this motor is producing Max HP (7HP). Since Hp is inverse to torque that means it's producing minimum torque.

HorsePower is roughly equivalent to Torque x RPM.

You definitely need the correct Field Map from Alltrax to get the top speed that motor can develop.

This is the Motor Curve for the Standard ADC motor, please note the maximum Armature current for a 5 amp field is 130amps, Your motor can go up to 200amps which means it is producing a lot more torque at higher RPM than the standard motor.

FYI I was talking with an engineer yesterday and the general rules are 6000 rpm limit for speed motors and 4000 rpm for torque motors. This is a combo motor so I'm not sure where in the range it will fall.
I will caution you.
I have seen a few members research and wring every last rpm out of their motors and the ones I'm recalling all ended up with motor failure.
