We were in low gear when the wheel broke and stayed there for a while.
2 x 2 x 45 x 60 / 11 / 15 = 65.5 times stall torque of a CIM seen at the dog. More like 44 times CIM stall torque when you account for voltage drop. Normally the wheels would have slipped long before that point was reached, but one was broken, so the torque was unable to turn the wheels. Don't know to what extent this is true but there was certainly more than the normal traction limited amount of torque being demanded of the dog.

I didn't mean 2 CIM units of stall torque, but twice the torque of what stall would cause at that stage.
I did however forget the ratio difference between high and low, thanks for correcting me there.
