WARNING!
The motor frame must be grounded and the windings should be discharged against the frame immediately after each measurement to avoid risk of electrical
shock.
If the reference resistance value is not attained, the winding is too damp and must be oven dried. The oven temperature should be 90°C for 12-16 hours
followed by 105°C for 6-8 hours.
Drain hole plugs, if tted, must be removed and closing valves, if tted, must be opened during heating. After heating, make sure the plugs are retted.
Even if the drain plugs are tted, it is recommended to disassemble the end shields and terminal box covers for the drying process.
Windings drenched in seawater normally need to be rewound.
3.3 Foundation
The end user has full responsibility for preparation of the foundation.
Metal foundations should be painted to avoid corrosion.
Foundations must be even, and sufciently rigid to withstand possible short circuit forces. They must be designed and dimensioned to avoid the transfer of
vibration to the motor and vibration caused by resonance.
3.4 Balancing and tting coupling halves and pulleys
As standard, balancing of the motor has been carried out using half key.
Coupling halves or pulleys must be balanced after machining the keyways. Balancing must be done in accordance with the standard balancing method
specied for the motor.
Coupling halves and pulleys must be tted on the shaft by using suitable equipment and tools which do not damage the bearings and seals.
Never t a coupling half or pulley by hammering or by removing it using a lever pressed against the body of the motor.
3.5 Mounting and alignment of the motor
Ensure that there is enough space for free airow around the motor. Minimum requirements for free space behind the motor fan cover should be achieved.
Correct alignment is essential to avoid bearing, vibration and possible shaft failures.
Mount the motor on the foundation using the appropriate bolts or studs and place shim plates between the foundation and the feet.
Align the motor using appropriate methods.
If applicable, drill locating holes and x the locating pins into position.
