2. HANDLING
2.1 Reception check
Immediately upon receipt check the motor for external damage (e.g. shaft-ends and anges and painted surfaces) and if found, inform the forwarding agent
without delay.
Check all rating plate data, especially voltage and winding connection (star or delta). The type of bearing is specied on the catalogue of all motors.
2.2 Transportation and storage
The motor should always be stored indoors (above –20°C), in dry, vibration free and dust free conditions. During transportation, shocks, falls and humidity
should be avoided. In other conditions, please contact TECHTOP.
Unprotected machined surfaces (shaft-ends and anges) should be treated against corrosion.
It is recommended that shafts are rotated periodically by hand to prevent grease migration.
Anti-condensation heaters, if tted, are recommended to be used to avoid water condensing in the motor.
The motor must not be subject to any external vibrations at standstill so as to avoid causing damage to the bearings.
Motors tted with cylindrical-roller and/or angular contact bearings must be tted with locking devices during transport.
2.3 Lifting
All TECHTOP motors above 25 kg are equipped with lifting lugs or eyebolts.
Only the main lifting lugs or eyebolts of the motor should be used for lifting the motor. They must not be used to lift the motor when it is attached to other
equipment.
Lifting lugs for auxiliaries (e.g. brakes, separate cooling fans) or terminal boxes must not be used for lifting the motor.
Motors with the same frame may have a different center of gravity because of different output, mounting arrangements and auxiliary equipment. Damaged
lifting lugs must not be used. Check that eyebolts or integrated lifting lugs are undamaged before lifting.
Lifting eyebolts must be tightened before lifting. If needed, the position of the eyebolt can be adjusted using suitable washers as spacers.
Ensure that proper lifting equipment is used and that the sizes of the hooks are suitable for the lifting lugs.
Care must be taken not to damage auxiliary equipment and cables connected to the motor.
