I am about to place an order for this motor, but I need to know what sort of abuse the 26" rim and spokes they lace it to can tolerate before I decide to part with my money. I am looking to initially run 4kW peak with a 3T wind at 72V/55A with 100A phase current using a Sabvoton sine-wave controller, with top speeds exceeding 45 mph. I just need for the motor and wheel to handle that load in stock form, and if it cannot, order it unlaced and lace my own.
After setting the motor up with active cooling, increasing that peak to 72V/100A with 120A phase current sounds reasonable, but I doubt that a bicycle rim could reliably handle that, and plan to upgrade to a moped rim in the long term.
It will be going on an enclosed KMX trike that is expected to weigh 100 lbs when complete, and the motor will be activated with a torque sensing PAS. With me plus camping gear, I expect a 300lb laden weight. I need a motor that has low enough cogging losses that my velomobile still functions well with a drained battery, and I think this is perhaps the best choice for a hub motor that I will find for my application.
The application spans the spectrum of "daily rider" to "race toy" to "long distance 30+ mph cruiser" and it must be still operable with the motor turned off.
