What kind of motor is suitable for the below requirements?
- 2700 rpm, needs to be accurate, not +- few rpms. I think the best approach is to use a hall effect sensor and adjust current/voltage on the fly? Or a better idea?
- Be as noiseless as possible. The noise 12V square fan motors make is perfect.
- Torque is not much of an issue as even though it is rotating a 100g load on top of it the load is supported by 4 bearings.
What motor am I looking for?
