I've got an electric scooter hub motor (48V 1500W), which is new for me, because I have 3 hub motors and I've seen much more motors, but the usual scheme is when I spin the wheel with my hand it's easy and it gives a whinning noise which will go away as the wheel slows down. But this beast motor just doesn't do the whinning noise, it's humming in a lower frequency and I can feel that it's "clicking" (don't know how can I say that, I can feel that the magnet is pulling and pushing the stator). It much harder to spin anyway. I tested it by shorting the phase wires together, because my first thought was that the phase wires were shorted, but no, when I shorted the wires the resistance was much more and it was't "clicking" that much. Can this motor be a well made product? It has almost no noise when load applied, the stator is skewed and 65 mm wide which is the widest stator I've ever seen. Of course the diameter is small, because it's a 10" motorbike wheel. I think the strong magnetic force and the small gap between the magnets and the stator gives this resistance or am I wrong? The pictures were taken before the renovation it's a 14 years old motor. It's not clean, Statorade added and it's ready to ride. I haven't tried it with much power, but I already felt that this is gonna be a powerful motor. It's a high speed motor (~50 km/h @ 48V) , but still had torque.
