1 GENERAL
Using many years of experience in production of high-voltage and low-voltage electrical motors the ìKONÈARGENERATORI I MOTORIî have developed a series of totally enclosed rib-cooled low-voltage squirrel-cage
induction motors frame size 280-450 - Series 6AZJ and 8AZJ.
Simple operation and robust design have made the three-phase squirrel-cage induction motor with totallyenclosed fan cooling (TEFC) the most reliable component of industrial drives. For frequency-controlled AC
drives, TEFC - motors are the natural choice for power ratings up to 1000kW.
This catalogue contains description and basic technical data of Series 6(8)AZJ 280-450. Series consists of five
shaft heights: 280, 315, 355, 400 and 450 mm and is covering power range from 37 to 1000 kW.
The basic characteristics of the Series are:
∗ high efficiency
∗ low noise-level
∗ insulation class F
∗ adaptability to various requirements of drives
∗ reliability in operation
∗ low maintenance costs
∗ simple installation and maintenance
2 STANDARDS
The motors are manufactured in compliance with HRN, IEC and according to VDE and DIN relevant standards.
On request, motors can also be constructed and tested according to other national standards.

MOTOR DESIGN
4.1 Stator
The stator frame is ribbed, made of gray cast iron or of welded steel plates. Motor feet are made of grey cast iron
and are fastened to the motor frame by high strength screws according to the prescribed tightening torque. Feet
of bigger motor are made of steel and welded to the frame of motor. Bearing shields are made of grey cast iron
or of welded steel plates. Motors of series 6AZJ have one external fan, and motors of series 8AZJ have two fans
(internal and external). Fans are made of siluminum or welded steel plates. Fan cap and fan cover, which can be
attached to the vertical motor with free shaft end turned downwards, are made of steel sheet. Stator core is
made of high quality steel sheets .
4.2 Rotor
The rotor core is made of high quality steel sheets, and rotor winding of aluminum cast in special casttechnology or of copper. The shaft is cylindrical, without ribs, and made of steel.
4.3 Insulation System
The insulation system of stator winding is in thermal class F and on special request motors can be manufactured
in class H as well. The stator winding is made of round or rectangular copper conductors insulated by high
quality varnish. Impregnation with impregnation varnish based on unsaturated polyester imide resin in
conjunction with the bandaging of the coil group, which provides good mechanical and electrical performances
and stability of the windings.
High quality materials and adopted technological process of impregnation ensure great mechanical and dielectric
strength, resistance to the negative effects of environment and reliability of motors. All used materials are
ecologically pure.
4.4 Bearings
Bearing assemblies with appropriate rolling bearings are situated in bearing shields. Grease lubricated rolling
bearings are used. Bearing at non driving end is fastened and bearing at drive end is free. For frame size 400 and
450 and type of construction IM 1001 fastened bearings are at drive end. Bearings are provided with grease
nipple, grease drain box and grease regulator. Regreasing is possible during motor running. Calculated L10
bearing life is not less than 40,000 hours. In case of belt transfer care should be taken about the permitted radial
loads. On special request, we manufacture motors with reinforced bearing assembly.
Table 2 contains types of bearings for motors of basic design.

4.5 Direction of Rotation
Motors of series 6AZJ are made for both directions of rotation and motors of Series 8AZJ for one direction of
rotation according to customer requirement. Direction of rotation confirms to IEC 34-8.
4.6 Terminal Box
The terminal box is made of cast iron or of welded steel and for motors of basic design is situated on top. The
cable introduction is realized through cable entries. Bigger motors can have the auxiliary terminal box situated on
top. The terminal box contains terminals for connection of motor to power supply and terminals for connection of
auxiliary units (special design). For protection against touch voltage there is a built-in plate with screws situated
in the terminal box and protection against fault voltage on motor frame.
4.7 Auxiliary Units
For thermal protection, motors can have temperature feeler built-in in stator winding and in bearing assemblies.
In order to prevent the moisture condensation during the still stand, air heaters are built-in in the interior of the
motor.
For speed regulation and protection the tachogenerator, pulse generator or centrifugal speed limit switch can be
installed. SPM nipples can be built-in in bearing assemblies. For type of cooling IC416 motors have the squirrel
cage fan driving motor situated outside of the motor under the fan cap.
5 TESTS
The tests are performed in compliance with IEC standards, and on special request according to other
international and national standards. Beside Routine Tests carried out on each motor, type tests are available
upon special request and at extra charge. Depending on motor rating, voltage and number of pieces, type tests
can be performed in factory test field and/or on site. Normally the following final tests are performed:
• Check up of fixing dimensions
• Winding resistance
• Insulation resistance measuring
• No-load test
• Short-circuit test up to rated current
• High voltage test
• Direction of rotation
• Terminals marking
6 DOCUMENTATION
Normally the following documents could be submitted:
• Technical data sheet
• Outline Drawing
• Transport, Storage, Installation, Maintenance Manuals
• Test Report.
On request other documentation can be submitted.
