3 1 GENERAL This catalogue contains description and basic technical data of three-phase high-voltage slipring induction motors with air - air heat exchanger. According to the execution of brushes and sliprings the motors are classified into two groups: - motors with permanently adherent brushes, designation 6 AK - motors with brush lifting device, designation 6 AP. Series consists of eight frame sizes: 355, 400, 450, 500, 560, 630, 710 and 800 mm. KONÈAR high-voltage induction motors of Series 6 AK(P)Z excel in up-to-date design, high degree of efficiency, insulation class F in VPI technology and other technical properties which completely meet the requirements of electrical drives. 2 STANDARDS Motors are designed according to Croatian Standards HRN, IEC standards and to relevant standards VDE and DIN.

6 4 MOTOR DESIGN 4.1 Stator Casing The stator casing is made of fabricated steel. Shape and dimensions are selected to ensure minimum vibrations and are designed to ensure easy transport and installation. 4.2 Stator Core with Winding The stator core is made of silicon steel sheet having low magnetic losses. Upon stacking and fixation of lamination on the appropriate device, the complete winding is inserted, fixed and connected. Afterwards, the core with winding is subjected to the manufacturing process of vacuum-pressure impregnation (VPI) to complete the insulating process. Upon the completion of the procedure, stator is inserted in the stator frame. 4.3 Stator Winding and Insulation Stator windings are constructed from copper rectangular wires. The wires are preinsulated with enamel varnish in combination with glass silk and varnish. The winding is of double layer type, made of individually shaped and continuously insulated coils. The basic materials are mica and epoxy resins. Prepared coils are continuously taped along the whole length with porous tapes on the basis of glass and mica paper. Such insulated and tested coils are inserted in the stator core, and then all the required connections and tests are carried out prior to vacuum pressure impregnation. The process of vacuum-pressure impregnation is followed by the stiffening process in furnace, tests and the insertion of the stator core with winding into the frame. Then the final tests are performed. The insulation system is of class F. It is moisture proof and it practically has no limitation with regard to climate conditions, salty atmosphere, acids and lies. By the mentioned insulation system, great mechanical strength of the winding ends has been obtained. There is no limitation to reversals at residual fields of any magnitude and phase angle.

8 4.4 Rotor Core with Winding The rotor core made from dynamo steel sheet is fitted directly on the shaft with axially cooled motors and on the shaft ribs with radially cooled motors. The rotor windings are of double layer type and constructed from copper rectangular wires. The connections of rotor conductors are made by hard soldering. The rotors bars are insulated by high quality insulating material class F and impregnated by adequate varnish. 4.5 Slipring and Brushes According to slipring and brushes arrangement motors could have two designs: - motors with permanently adherent brushes, designation 6 AK - motors with brush lifting device, designation 6 AP Motors series 6 AK should be used for speed regulated drives (by additional resistance in rotor circuit, subsynchronous cascade), with motors for electrical braking, with automatic rotor starters. Motors series 6 AP have devices which lift brushes from contact surface and short circuit sliprings, after starting period. Devices can either be automatically or manually operated. 4.6 Bearings Grease lubricated rolling bearings or oil lubricated slide bearings as appropriate to speed and bearing loading are used. On horizontal motors of all sizes, oil lubricated slide bearings are an option. Normally, bearings are installed in bearing endshields. Rolling 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 50,000 hours. Horizontal motor locating bearing is placed on DE. Vertical motor thrust bearing is placed on the top of the motor. Slide bearings are equipped with bearing shells spherical seated in the housing. Bearings are fitted with loose lubricating rings. Depending on speed of rotation and on bearings specific load, bearings are available either with natural cooling or with connections to a lubricating system. The bearing oil-ring maintains lubrication when force-feed oil supply fails, allowing the motor to come safely to a standstill. Normally, slide bearings are non-locating bearings. To prevent oil vapor ingress into the motor enclosure, the inner side of bearing endshield is provided with additional motor seal.
