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

Mechanical Installation

3.3.4 Mount the DriveMotor

Illustration 3.4 Installation Orientation, IP54/UL Type 3R
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 1 DriveMotor are mounted close by,
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 on the frequency converter,
as this foil 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 damage results in
an increase in bearing noise and a significant reduction
in bearing life.

Operating Instructions

3.3.5 Shaft Alignment

When the application requires direct coupling, the shafts
must be correctly aligned in all 3 planes. Incorrect
alignment can be a major source of noise, vibration, and
reduced bearing life.
Make allowance for shaft end float and thermal expansion
in both axial and vertical planes. Flexible drive couplings
are preferred.
