The supporting structure for the electric machine must be such that the machine can be mounted

using its allowed mounting positions, see chapter

Allowed mounting positions

The mounting space must be adequate for the machine mounting and possible auxiliary

components. See the length and the diameter data of the electric machine from the product

drawing. Main dimensions of the electric machine are shown in the Figure below (the illustration

may diﬀer from the actual electric machine).
The electric machine has a SAE 3 ywheel housing in N-end. The D-end has a circle of bolt holes

for fastening. See speci c installation instructions.
