Figure 7. Main dimensions of the electric machine
For all dimensions of the electric machine, see the product drawings.
Shaft alignment and load
Improper alignment (misalignment) may result in bearing overloads, premature bearing failures, vibrations and shaft
failures. Flexible coupling does not compensate for excessive misalignment.
The type of electric machine shaft is DIN5480 SplineW40x2x18x8f. Recommended female
connection counterpart is of type SAE 6 Mating transmission housing ange.
Alignment between the shaft and mating structure must be accurate.
The misalignment can be parallel or angular misalignment, or combination of those. With parallel
misalignment, the center lines of both shafts are parallel but they are offset. With angular
misalignment, the shafts are at an angle to each other. Figures below illustrate the parallel and
angular misalignment.
