66 B. SkalaThe squirrel cage rotor has a cooper winding which consists of bars and twoshort circuit rings. The bars and rings are brazed. Over both short circuit rings,shrung-on links are placed.a) b)Fig. 1. (a) Deformations of the bars (b) Squirrel cage rotor winding, ANSYS modelBased on the practice of the company, fatigue failure occurs sometimes onthe rotor bars, located near to the short circuited ring. The similar problem isbeing solved also by other companies, e.g. Alstom.2. THE RAILWAY ROUTE PRAGUE – CESKA TREBOVAThis three-system locomotive will be operated mainly on Czech high speedcorridors. For our purposes, the railway route from Prague to Ceska Trebovahas been chosen. The data were obtained for passenger fast train of a totalweight 450 t and a freight train of a total weight 1400 t. The length of the route is165 km, maximum allowed speed is 160 km.h -1 . Both directions were observed.Both trains stopped only two times, in Kolin and Pardubice. The braking energywas recuperated back to the trolley line.

METRO VLIt is assumed that nowadays production downtimesdue to empty machine hoppers do not occur.Hopper loaders automate the material feed to themachines. The cost advantage is obvious: cleanproduction sites, no material loss due to spilled material,no risk of injury associated with manual fillingof machine hoppers, better deployment ofpersonnel and, in conjunction with material storagebins, no material mistakes. Finally, no productiondowntimes.METRO MES 10METRO VLVenturi compressed air loader for small quantities.METRO HES 50METRO MES 10Hopper loader with integrated vacuum motor, themost cost saving solution for a material throughputof up to 10kg/h.METRO HES 50Hopper loader with vacuum motor, powerful andlow noise for a material throughput of up to 50kg/h.METRO HES 250METRO HES 250Hopper loader with brushless vacuum motor,maintenance-free and powerful for a materialthroughput of up to 250kg/h.METRO HPS 06METRO HPS 06Hopper loader to be used in small systems.METRO HBS 750/2Hopper loader with a three-phase blower for highermaterial throughputs.METRO HBS 750/2METROMIXProportioning valve to add regrind may be suppliedor retrofitted as necessary.METROMIX4

METRO HBSThree-phase loadersThe METRO HBS models offer a wide choice ofloader-blower sets and are designed for higherthroughputs, from 250 up to 750kg/h.The units are supplied with a separate three-phasefloor standing blower station which is low noise andmaintenance free. The control panel is located at aconvenient height, eliminating the need to climbonto the processing machine. An alarm indicatesinsufficient material.Highly efficient automatic implosive filter cleaning isstandard on all METRO HBS loaders.METRO HBS with blowerMETRO HBS units are also available with twomaterial inlets. A separate mixing valve is notneeded, as the METRO HBS loader has an integralproportioning function for virgin and regrind material.The ratio between the materials is preciselyadjustable, so that the loader delivers a completelyhomogeneous mixture.Up to two loaders plus a blower station can becontrolled through a single control panel. In effect,processors can set up a small conveying system,with METRO HBS loaders serving either twomachines or one machine and a drying bin.METRO HBS 250/27

METRO HPS/HPGLoaders for small systemsModularity• The Motan METRO range with 0.5 to 30 litrescapacity.• Modular design allows easy adaptation.• Machine loaders replace the storage bins on theprocessing machines.• The option of either a glass or steel hopper bodyis available for most loaders.METRO HPS 06Implosion valveAll METRO HPS/HPG material loaders are fittedwith a vacuum valve. The valve opens the vacuumline when material is being conveyed and closeswith an airtight seal after the conveying phase. Thereduced pressure in the loader then causes theimplosion valve to open suddenly for a short time.The shock of this implosion cleans the materialseparation screen after each conveying cycle.METRO MPG 1.5Convey controlGRAVInet is an automated control system forhopper loaders. The integrated convey control atthe GRAVICOLOR blending units allows the controlof up to seven hopper loaders.GRAVInetGRAVInet8
