A lot of brush-less, in-runner motors I have run into happen to operate without any sensing capacity. This means the motor doesn't know where it is in a cycle. My friend Greg asked me to print these designs on a Stratasys for this exact purpose. The three hall effect sensors sit in the outer ring which is connected to the frame of the motor itself. As the rotor moves, the hall effect sensors pick up the magnetic field sequentially and notify the motor controller where the shaft sits.
