Radial alignment:
The rotor axis and the axis of the speed sensor must be
along a line at right angles to the stator platform. The
nominal radial distance is crucial for radial alignment (see
Fig. 5.11). The optimum distance is 2.5 mm and is
achieved when the rotor and the stator are in precise
radial alignment.
