6 The Runners System motors A Motor for 100 Hz Characteristics and any Voltae Worldwide WATT EUSAS motors are top quality, three-phase AC industrial motors from Watt Drive s customer-oriented motor system. EUSAS stands for EUrope - US ASia and means that the wide voltae rane and simple voltae selector in the terminal box enable the motor to be operated with virtually any supply voltae and frequency worldwide. 100 Hz Characteristic - Double Power In frequency inverter operation WATT EUSAS motors can be controlled usin the 87/100 Hz voltae/frequency characteristic without special windins. As a result, the same motor size can output up to double the power without bein overloaded. Connection Modes The Watt Drive quality motor uses a 9-pin terminal block and therefore can be switched in star, delta, double star and double delta with its wide-rane windin. This way, the motor still covers a lare part of worldwide supply voltaes. EUSAS motors up to incl. frame size 100 can be operated in the followin voltae rane: V (D), V (DD), V (Y) and V (YY). From frame size 112 followin voltae ranes are possible: V (D), V (DD), V (Y) and V (YY) each for 50 and 60Hz.

8 The Power Makers Geared motors Top Quality Geared Motors Watt Drive eared motors are the electro-mechanical key elements for low backlash, smoothly runnin and hihly dynamic drive systems. Our hih-performance ear units are built to withstand the touhest industrial applications. The ear housins are machined on all sides and permit diverse mountin positions and applications, makin them much souht after in the industry. As a result our eared motors are often to be found as part of our customers own machines. The smooth runnin of Watt Drive ear units and the outstandin load capacity of WATT teeth are achieved with 3D desin supported by FEM (Finite Element Method). This tooth eometry uarantees optimum rollin contact under load. The special tooth root desin in combination with tooth helix anle, tooth depth, the materials used and surface finish maximizes load capacity. This hih earin capacity enables smaller wheels to be used for the same torque, and smaller ears with exceptional power density also increase reliability. Watt Drive eared motors are consequently incredible space savers. Gearin manufactured with such microeometric precision allows the earin play required for troublefree rollin contact to be substantially reduced and therefore the ear backlash to be minimized. Double chamber shaft seals developed by Watt Drive are used as standard in parallel shaft, shaft mounted and helical worm ears for a hih level of tihtness. We Meet Individual Customer Specifications The innovative Watt Drive modular ear system consists of a minimum number of different parts. Intellient part desin enables them to be used in various types of ear units. Individual customer specifications can therefore be met efficiently in a short space of time. Watt Drive s modular ear technoloy meets the requirements of advanced drive systems: Excellent power density Minimum backlash Smooth runnin Diverse mountin options Maximum reliability Hih variability Modular Gear System Helical, parallel shaft, shaft mounted, helical bevel, helical worm and worm ear units 8

14 Our Drive - Your Solution Environmental industry Applications for outdoor and/or aressive environments (such as sewae treatment or bioas plants) call for special measures to ensure years of reliable operation for the drives used: special varnishes and coatins, protective caps, anticondensation heatin, rust-proof brake systems. Steel industry Day-to-day operations in the steel industry involve extreme impact stresses, the need to accelerate enormous masses, in red-heat temperatures. The drive system used have to be reliable and require little maintenance. Theatre and stae technoloy The noise emitted from the installed drive technoloy may not interfere with operations in the theatre at all. The authorized noise levels are in accordance with the correspondin norms and have to, on all accounts, be observed. 14

15 Materials-handlin technoloy Stron and safe are the principle requirements for materials handlin technoloy. Full antry cranes, level luffin and slewin cranes, screenin machines and conveyors all have to handle extreme loads reliably for many years. Aerial cableway technoloy Aerial cableway transportation is subject to the most strinent specifications and standards, which all have to be reliably fulfilled by the drive technoloy used. Thanks to our ISO 9001:2000 quality manaement, our standard is consistently at this hih level. Mineral processin industry The manufacture of asphalt concrete at a location with rouh environment conditions calls for maximum process safety from -40 to +60 C. Drives for such extreme ambient conditions also require various additional options (e.. seals, etc.). 15
