Handling the FC motor
Handling and lifting of VLT DriveMotors (FC motors)
must only be undertaken by qualified personnel. Full
product documentation and operating instructions
must be available together with tools and equipment
necessary for safe working practice. Eyebolts and/or
lifting trunnions supplied with the FC motor are
designed to support only the weight of the FC motor,
not the weight of the FC motor and any auxcillary
equipment attached to it. Be absolutely sure that
cranes, jacks, slings and lifting beams are capable of
carrying the weight of equipment to be lifted. Where
an eyebolt is provided with the motor, this should
be screwed down until its shoulder is firmly against
the face of the stator frame to be lifted.

Bearings
The standard solution is fixed bearing in the drive
side of the motor (shaft output side).
To avoid static indention, the storage area should be
vibration free. Where exposure to some vibration is
unavoidable, the shaft should be locked. Bearings
may be fitted with a shaft locking device which should
be kept in place during storage. Shafts should be
rotated by hand, one quarter of a revolution, at weekly
intervals. Bearings are despatched from the works
fully charged with lithium based grease.

) tensile steel. Drive end shafts are provided
with a tapped hole to DIN 332 Form D and a
closed profile keyway as standard.
Balance
All motors are dynamically balanced, to ISO 8821with
key convention to IEC 60034-14.
