Is it possible to calculate torque required to rotate wheel but weight of wheel is unknown?

  • $\begingroup$ A wheel will rotate just as long as you can overcome the friction of the system. So even a very low torque motor can get a well balaced wheel system to rotate, its just going to take a long time to accelerate the system. So no with this info alone you can not answer anything. Not that knowing the wheel geometry helps $\endgroup$ – joojaa Aug 10 '18 at 9:01
  • $\begingroup$ Better yet, (since you didn't specify), what torque is required to rotate the wheel about a non-axle axis, when the wheel is spinning? (gyroscopic torque) $\endgroup$ – Carl Witthoft Aug 10 '18 at 17:27
