ABB High dynamic performance HDP Serie Manuel D'installation, D'utilisation Et De Maintenance page 15

ENGLISH
HDP motors for frame sizes of 80, 100, 132, 160 and 180 are designed according to IEC 60034-7 by default for IM B35
installation that also allows IM B5 and IM B3 installation.
Other mountings are available as an option.
Correct alignment is essential to avoid bearing, vibration and possible shaft failures.
Procedure
1. Mount the motor on the foundation and/or the mounting flange using appropriate bolts or studs, and place
shim plates between the foundation and the feet.
2. Align the motor using appropriate methods.
3.
If applicable, drill locating holes and fix the locating pins into position.
4.
Mounting accuracy of the coupling half: check that clearance b is less than 0.05 mm and that the difference a1
to a2 is also less than 0.05 mm. See Figure 7 Mounting of half-coupling or pulley.
5.
Re-check the alignment after final tightening of the bolts or studs.
Do not exceed the permitted loading values for bearings stated in the product catalogues.
6.
Check that the motor has sufficient airflow. Ensure that no nearby objects or direct sunshine radiate additional
heat to the motor.
7. For flange mounted motors (e.g., B5, B35, V1), make sure that the construction allows sufficient air flow on the
outer surface of the flange.
1.4.6 Radial forces and belt drives
Procedure
Check that the motor shaft is parallel with the drive shaft.
Belts must be tightened according to the instructions of the supplier of the driven equipment. However, do not
exceed the maximum belt forces (i.e., radial bearing loading) stated in the relevant product catalogues.
WARNING:
1.4.7 Cabling and electrical connections
The terminal box on a standard HDP motor normally contains winding terminals and at least one earthing terminal.
In addition to the main winding and earthing terminals, the terminal box can also contain connections for
thermistors, heating elements or other auxiliary devices.
Suitable cable lugs must be used for the connection of all main cables. Cables for auxiliaries can be connected into
their terminal blocks as such.
Motors are intended for fixed installation only. Unless otherwise specified, cable entry threads are metric. The IP
class of the cable gland must be at least the same as those of the terminal boxes.
A certified conduit hub or cable connector has to be used at the time of installation.
NOTE:
Unused cable entries must be closed with blanking elements according to the IP class of the terminal box.
The degree of protection and diameter are specifiedin the documents relating to the cable gland.
WARNING:
Earthing must be carried out according to local regulations before the motor is connected to the supply voltage.
NOTE:
Excessive belt tension will damage bearings and can cause shaft damage.
Cables should be mechanically protectedand clamped close to the terminal box
to fulfill the appropriate requirements of IEC/ EN 60079-0 and local installation
standards.
Use appropriate cable glands and seals in the cable entries according to the type
and diameter of the cable
When the ambient temperature exceeds +50°C, cables having a permissible
operating temperature of +90°C as minimum shall be used. Also, all other
conversion factors depending on the installation conditions shall be taken into
account while sizing the cables.
