4. Motor installation
4.1. Preparation and lifting
Remove the rotor locking devices (52, 16, 58, 59, 40) from the ends of the shaft, see Figure 6.
Remove the corrosion protective coating as per chapter 3.3.
Always use the holes for the lifting eye bolts when lifting the traction motor, see chapter 3.1.3 for further
details about lifting.

Removing the rotor shaft locking device.
4.2. Installation of coupling
To ensure low noise and vibration levels, the alignment between the motor shaft and the mating coupling
must be accurate. The higher the motor operating speed the higher accuracy is needed.
For side support mounting. Some type of flexible coupling shall be used, and the geometrical tolerance
demands can differ between type and supplier. See manual from the coupling supplier.
For dimensions involving the motor shaft, flange, and side mounts, see the outline drawing. The product
code is visible on the nameplate, see Figure 2.
NOTE: In applications with severe vibrations, only flange mounting is not recommended. Additional
side support may be needed. Please contact your local ABB sales office for technical support.
NOTE: Lubricate the splines with a suitable molybdenum disulfide grease prior assembly.
