3.4 Requirements for the mounting surface
Picture 3.3: Flatness and parallelism of mounting surfaces
The mounting surfaces of both magnet yokes and coil units have to be flat
to prevent them from being submitted to bending forces (see picture 3.3
and table 3.5).

Table 3.5: Installation tolerances U-series
The track of the magnet yokes – from now on to be called the magnet track
– and the coil unit have to be aligned with respect to each other. Note that
this has to be accomplished by the machine’s construction.
Picture 3.6: Air gaps and axial references, schematically
Axial reference for the magnet track (MR, see picture 3.6) can be obtained
by the use of:
■
Dowel pins in the middle yoke of a short track
■
Dowel pins along the complete side of a long track
■
Milled reference along complete side of a long track (inner radius <
0.2mm), or
■
Alignment by hand during mounting
Axial reference for the coil unit (CR, see picture 3.6) is obtained by:
■
Two dowel pins beside the first and last bolt of the coil unit
■
Milled reference along complete side (inner radius < 0.2mm), or
■
Alignment by hand during mounting

Only use the aluminium side of the UC and UF series
housing as mounting surface (see picture 3.4). The
epoxy/power cable side is not suited for alignment.
