Note that the controllers from big brands typically call out their peak ratings, not the continuous ratings. So like for your application you will need something like a 300A controller.Ya I suppose that just because it looks like an me0709 and it's made for 24-72v, it doesn't mean that it is an me0709. I don't want to go overboard on the controller but I also don't want to limit the motor by the controller.
Looks good to me, assuming you want regen and are happy with the voltage range. Is there any chance you will run the thing at a higher voltage in the future ? I think that motor won't be upset with 100V.Okay. Do you think the Kelly kdz72301 would be a good fit.

20s is 84V at full 4.2v per cell... You should also check what is the actual max voltage for the 72V Kelly controller.Hmm. I don't know. I picked 72v because I have a 40s Chevy volt battery left over from a solar storage project. Gives me 7.7 kwh as 20s2p battery. I could switch it to just a single 24s battery but then I'd only have 4.6 kwh with reduced run time. Actually hadn't even considered it. Maybe I should.
In the words from the Book of Wisdom, citation needed.The max continuous current rating is determined by the heat, and how fast it can get rid of the heat, not the wires or brushes.
I don't see where that page brings up the topic of brushes and internal wiring (besides the windings).As you requested:
Continuous Duty Motor | Classes of Duty | Selection of MotorThere are two types of Continuous Duty Motor — continuous duty at constant load and continuous duty with variable load cycle. In the former the load torque remains constant for a sufficiently longer period.Classes of Duty-Continuous Duty,Short time duty,Intermittent Load Cyclewww.eeeguide.com
