Stator alignment (rotational speed measuring
system)
For measuring mode to operate perfectly, the speed sen
sor must be placed at a defined position to the rotor ring
gear. When the radial and axial alignment of the stator is
accurate for torque measurement, the alignment of the
rotational speed measuring system is also correct.
Axial alignment:
At the factory, the sensor head of the rotational speed
measuring system must be adjusted so that when the
axial alignment of the stator is exact (antenna ring posi
tioned precisely above the rotor winding carrier), the sen
sor is in the correct position to the rotor ring gear.
