When you spin a motor shaft by hand with the motor out of the car then no, its not going to feel like a bearing even though the shaft is riding on bearings. It will actually feel like a bunch of "clicks" (for a lack of a better term) because as you spin the shaft the motors magnets are still pulling on the rotor. So each "click" you feel is the rotor turning past the magnets field if that makes sense.Perfect. Exactly what I was asking. I'll be picking 1 up today. My big rock seems to heat up kinda fast . motor after 20ish min is "not too hot" to make me take finger off but plenty warm enough to have asked.
if I turn the pinion, when it was disassembled from mount etc, should that feel smooth? Or bumpy? Meaning smooth like a bearing feels or no?
Yep, if it feels "smooth", that means it's dead. Kind of like the blx2050kv of mine that got up to 259F. I barely feel the magnetic field at all when spinning the shaft by hand. Prior to that, I almost couldn't rotate the motor without a pinion on it or using pliers on the shaft.When you spin a motor shaft by hand with the motor out of the car then no, its not going to feel like a bearing even though the shaft is riding on bearings.
