Mounting the electric machine
Do not exceed the maximum axial and radial forces calculated for the shaft.
Document Allowed bearing loads for EM-PMI machines DOC-000454 gives more information
about this. Contact Danfoss to obtain the document.
Do not use the N-end of the electric machine for mounting the electric machine.
Refer to Chapter Allowed mounting positions for the correct mounting positions of the electric
machine.
Mount the electric machine on a correct supporting structure as discussed in Chapter Supporting structure
requirements .
Horizontal assembly
1. Lift the electric machine to the correct mounting position. See Chapter Lifting for details .
2. The electric machine is mounted using its foot mount (stand) and, if needed, D-end flange (SAE1/2
transmission housing). SAE 1/2 mating transmission housing is required as a mating flange.
3. Align the electric machine with the mating housing alignment. See Chapter Shaft alignment and load .
4. Connect the shaft of the electric machine, make sure to use full spline engagement. Lubricate the
spline.
A recommended spline lubricant is a 50/50 compound of a high temperature grease and a
molybdenum disulphide powder. When applied initially and re-applied at proper intervals, it
will help prevent fretting corrosion and premature wear. This lubricant is not soluble in oil
and should be used accordingly. Further products which may be recommended are Molycote,
Metaflux, Never Seeze, Optimol and similar.
5. Attach the mounting bolts (for correct bolt type see Figure Mechanical mounting connections of the
electric machine (horizontal mounting) . For steel housing the minimum length of the bolt is 40 mm and
for aluminum housing 45 mm.
Use tightening torque of 69 Nm for the flange mounting bolts and 200 Nm for the foot
mounting bolts.
