Rotors are dynamically

balanced at full

operating speed.

The rotor

The key to long life for the rotor lies in ensuring

very low vibration levels. This is achieved through

robust construction and careful balancing of each

completed unit.

Rotor shaft material is selected according to the

duty and the ambient conditions. The spider

beam welds and subsequent stress relieving

are performed according to rigorous norms and

subjected to stringent inspection.

Squirrel cages are made from copper or copper

alloy dependent upon the loading and individual

customer requirements. Swaged rotor bars pro-

vide additional stiffness enabling the motors to

withstand long periods of heavy use.

Performance and reliability start here

Special accessories for

noise reduction are

available.

The statorThe stator core is welded and machined to form

a compact unit. Radial air ducts ensure uniform

and effi cient cooling. The stator core forms a solid

block that retains its rigidity throughout the life of

the motor. The complete stator is vacuum-pres-

sure impregnated.

Easy-to-connect

terminal boxes

All terminal boxes are

designed to facilitate cable

connection and shorten

installation time. Boxes

are available in explosion

proof or increased safety

execution.

Micadur Compact

Industry insulation

system

ABBs world renowned

insulation system gives

reliability and long life. The

windings and connec-

tions are insulated with

Mica- based tape. When

the windings are in place

the whole stator is im-

pregnated in the vacuum

pressure impregnation

(VPI) process. Class F is

standard.

Coil locking

Well developed and proven

methods for locking coils

into slots and bracing coil

ends ensure long term

reliability.


8/12

The frameThe compact, rigid, welded frame construction is

designed to reduce overall weight, provide high

lateral and torsional stability and ensure low vibra-

tion levels in all operating conditions and over the

whole speed range.

The bearingsThe bearings are designed for reliable, continuous

operation and ease of maintenance. Depending on

the power and speed of the motor the right choice

of bearing is made. Anti-friction bearings with apredicted service life of over 100,000 hours can be

specifi ed. ABB also offers spherically seated, self-

aligning sleeve bearings. For greater radial load

capacity, cylindrical roller bearings can be used at

the drive end with a deep-groove ball bearing at

the non-drive end. All bearings feature a sealing

system that prevents dust penetration.

Easy-to-connect terminalboxesThe standard terminal box is available in EEx d

fl ame-proof or EEx e Increased Safety execu-

tion.

Other types of connection boxes can be provided

on request (EEx e execution certifi ed).

Following types are available:

Phase separated

Phase segregated

Phase insulated

With different types of cable connections such asRaychem termination or Elastimold.

The box is turnable by 90 to provide cable entry

from any direction.

The terminal boxes are widely dimensioned in

order to facilitate cable fi tting as much as pos-

sible.
