Mount The Drivemotor; Shaft Alignment - Danfoss VLT DriveMotor FCP 106 Operating Instructions Manual

Mechanical Installation

3.3.4 Mount the DriveMotor

3 3
Illustration 3.4 Installation Orientation
Mount the DriveMotor with adequate access for routine
maintenance. Observe the recommended clearances, see
chapter 7 Specifications. A minimum of 0.75 m clearance
around the motor is recommended, both for working
access and adequate airflow at the motor fan inlet. See
also chapter 7.1 Clearances, Dimensions and Weights.
Where more than one DriveMotor is mounted in close
proximity, ensure that there is no recirculation of
exhausted warm air. Foundations must be solid, rigid and
level.
NOTICE
Electrical installation
Do not remove the top foil inside the inverter part, as
this is a part of the protective arrangements.
Fitting pinions, pulleys and couplings.
Drill pinions, pulleys and couplings to standard limits and
fit on the shaft with a screwing motion. Ensure correct
guarding of all moving parts.
NOTICE
Tapping of fittings onto the motor shaft, with a hammer
or mallet, causes bearing damage. This results in an
increase in bearing noise and a significant reduction in
bearing life.

Operating Instructions

3.3.5 Shaft Alignment

When the application calls for direct coupling, the shafts
must be correctly aligned in all three planes. Bad
alignment can be a major source of noise, vibration, and
reduced bearing lifetime.
Make allowance for shaft endfloat and thermal expansion
in both axial and vertical planes. Flexible drive couplings
are preferred.
