100 W
This is a small ATV, the gas engine was 11kW so I think It will be fine with the same electrical power

I think Luke "liveforphysics" did, ask him.devmanner said:Also has anyone pushed a golden motor 10kw liquid cooled motor to see what it can handle?
I have heard that they are not going to be making the 120V models. I think for safety and hardware reasons. If you choose a high-enough RPM motor, you don't need the added volts anyhow. Design it from the start for a 20S battery, stay on the "sane" side of the voltage spectrum, and choose the rest of your components accordingly. 600A is enough to push ~43KW into a motor.devmanner said:Do you know how to get your hands on the mobipus 12250? That would be nice step up from the 72200 and not crazy like the 72600. I'm looking for continuous 20kw and peaks of 30kw for a cr80 conversion. Also has anyone pushed a golden motor 10kw liquid cooled motor to see what it can handle?

Ohbse said:I have mounted a hydraulic pressure transducer on my left brake lever to act as a kinda of virtual rear brake, unfortunately this wasn't working particularly well, the reported voltage on the analogue brake input was lower than I expected, maxing out at around 2.1v on a 5v sensor. While all of the threshholds are configurable, when I set it up for the voltage swing I was seeing it would only work intermittently and drop out at higher brake force.
It turns out the unexpectedly low voltage isn't actually low, it just displays at 1/2 of reality in the real time stats and logging graphs. Having configured all the thresholds for double the numbers it works beautifully!
Now with mild slip regen when off throttle and then my left lever acting as incredibly smooth and intuitive regen braking right down to practically stopped I really don't have to ever use the front brake. The sensation is not at all dissimilar to large hydraulic brakes on the rear, just much more confidence inspiring than bicycle parts.
At speed it's easily hitting my maximum regen limit of 50a back into the battery and can be precisely controlled to threshold of lockup at any speed you like, even down at walking pace.
litespeed said:I agree on the 3.5T not being the best one. I wanted the 4T and had the deal signed and sealed with QS but when I found the 3.5T laced with a matching front wheel for almost $500 less than QS, I jumped ship.
Sounds like this might be pretty equal to the MaxE in terms of total performance then. I can dial in 196 amps and 360'ish phase amps on the MaxE.
Sounds like I just need to try a QS 273!

kingjamez said:Care to share details on your pressure transducer? It sounds like you aren't running a brake on the rear at all? Very interesting. I'd love to do that as there isn't very much clearance on my motor between the 203mm disc / frame/ phase wires .
Does the Mobipus have a regen vs. battery voltage setting? If so does the amount of available regen phase in as the voltage drops or does it only start at a certain pack voltage?
That's actually a little surprising - I mean, if it doesn't have these parameters, I don't think it can do true field-oriented control. Doesn't it have a discovery mode to measure them? Maybe it does but it's locked down for end users?Ohbse said:Only killer is it requires accurate measurements of the motor including inductance, which I've been unable to find for the qs v3 205 3.5t

I have the same motor run by a MaxE and pretty much love everything about it accept throttle response at take off. I'll be interested in hearing how yours does. The Adappto has a delay of some sort that can not be adjusted out unlike the near instant response of the Lyen controller I had used before on different motors. I want that "gas motorcycle" throttle type response for pulling the front end up at low speeds when needed.
Ohbse, do you have any comments on throttle response since you also have the same motor?
Thanks,
Tom
