1 GENERAL Using many years of experience in production of high-voltage and low-voltage electrical motors the -GENERATORI I MOTORI 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 totally-enclosed 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.

4 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 cast-technology 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
