I bought a 1500w motor & supposedly compatible controller from ebay. I put it together, and it worked good!
I let it sit a few weeks. Hub is now FROZEN. it has ~2" of free roll then hard stop. I CANNOT turn the wheel past this point.
- I unplugged everything from the hub. It remains frozen.
- The hub itself was outside but under a tarp during hurricane Ida. I set the controller up AFTER that. Worked good over a week of testing. It has seen a little rain since, but it lives in a carport.
- A friend suggested that the motor might actually be a 1kW not a 1.5kW, and the controller toasted it? Seems iffy, because it was fine on the last ride.
- With ~20 lbs of torque the wheel will not spin at all. I am hesitant to push harder.
I'm stuck! Do you got any ideas? Thanks!
There will be no technical support from the seller, it came from a Chinese seller via Ebay.
Are there any rust marks visible on the outside?
Yes - the spring-wire-protector-thingy at the axle shows some corrosion.
Can you roll the motor backward at all past the 2" window or is it a hard clonk at both limits?
Hard lock in both directions, but no resistance till it locks.
