H3 Robot In Hub Motor Rotor

H3 Robot traction will be provided by a specially built stepper motor, that will be manufactured to be completely contained within the wheel hub.

The tire will be press fitted into the wheel hub, which forms the basis of the motor rotor.

Now this may seem odd, since the rotor usually is in the center of the motor, but in this case it will be on the outside of the motor stator.

This seems reversed because motor functions, in an in hub motor, are kind of reversed, since it's not an axel that revolves, but instead it's the wheel that revolves around a static axel. In other words, the axel is fixed, it does not rotate.

To accomplish this, the wheel hub must function as the host of the stepper motor rotor, which means that the hub must have a bunch of magnets securely attached to it. Once again, this is so, because the motor works in a reversed logic to a typical motor. In other words, it's the rotor that gets the magnets instead of the stator, which is the reverse of a typical electric motor.

By definition, the rotor is the part of the motor that rotates, and the stator is the part that remains static or fixed, i.e. it does not rotate.
