It just occurred to me that there are only 3 wires coming from the spindle motor. So where are the wires for the Hall Effect sensor? Does it not have one? Carbide says they have a closed loop speed control, how is this achieved with only the 3 phase wires or am I missing something?

wait, I feel stupid. I saw from the company that distributes the nomads spindle motors that they all had Hall effect sensors with them. So I thought mine was missing something but didn’t stop to think about the back emf for speed control.
