Box 47 43, D Nürnberg, Germany Siemens Aktiengesellschaft Subject to change without prior notice Order No. E20001-P630-A160-V Printed in the Fed. Rep. of Germany Dispostelle 27601/SEK U WS

2 Unique: The synthesis of a compact motor design and modular cooling. H-compact PLUS Highest output, reliability, efficiency, and modular cooling design: The new H-compact three-phase high-voltage motors are, in their class, unique and that worldwide. This is new for modular motors up to approx. 5 MW: The motor enclosure and the bearing brackets are made from a high-quality cast iron. This means that the H-compact PLUS is not only highly loadable, but they are also really compact, e. g. for refiners, mills, pumps or compressors. With shaft heights of 500 mm or 560 mm. With degree of protection IP 55 or IP 23. Water- or air-cooled. The advantages: All of the modules are perfectly harmonized with one another; it is easy to change from air- to water cooling. This means, you have precisely the power you require at your fingertips: H-compact PLUS is at home in any industrial sector, whether in the basic materials industry, chemical-, water treatment-, cement plants or in the process industry. The advantages at a glance: Excellent operating data, especially regarding efficiency, power factor and starting characteristics Compact type of construction using a rugged cast iron design high output from a low motor size Improved cooling for uniform, low temperature rise low cooling power requirement Low cooling noise due to optimized ventilation open-circuit air cooling with special air intake and discharge design noise-dampening cooler assembly mounting High vibration quality as result of low excitations stiff cast iron housing good damping characteristics of the cast iron housing Low operating costs, as the motors are quality products with a long service life, low power costs and low maintenance costs. 2

3 Cooling modules Air-water cooler 1RN4 With H-compact PLUS with water cooling, you are always optimally equipped. It does not make any difference as to whether you are indoors or outdoors, whether there is significant dirt build-up, moisture or aggressive chemicals. The top mounted air/water heat exchanger guarantees the highest cooling performance, with minimum heat loss to the immediate environment. Air-air cooler 1RQ4 The alternative solution if no cooling water is available and for difficult ambient conditions: H-compact PLUS with top mounted air/air heat exchanger. A shaft-mounted fan on the nondrive end ensures an optimum cooling air flow. Open-circuit air cooling 1RA4 The cooling air is drawn-in, fed through the inside of the motor and discharged the efficient cooling without heat exchanger. 3 4

5 Unified technology Skrzynka zaciskowa 315 A, 6 kv max. przekrój przewodów 1 x 3 x 240 mm 2 Small, compact, but still versatile With H-compact PLUS, all of the various motor modules and components are perfectly harmonized with one another. Whether enclosure, bearings, active parts, cooling or ventilation system. That makes the motor small and compact. And you not only save space, but it is also easier to install the motor due to the large degree of flexibility when laying-out the interfaces. For example, the numerous ways of arranging the terminal box. Rugged and quiet with cast iron The enclosure and bearing brackets of the H-compact PLUS are manufactured out of cast iron. Cast iron parts dampen noise and are especially resistant to corrosion. And not only that: They keep on top of everything even when used under tough conditions i. e. stiff and rigid, for example, using inner ribs which are optimized using computerbased simulation. Flexible for three cooling types Water cooling with heat exchanger, or open-circuit cooling; or air cooling with heat exchanger the enclosure of H-compact PLUS is the perfect fit for any cooling system. It is easy to changeover from air to water cooling. High output density is always guaranteed: The power loss is effectively dissipated through the inner cooling circuit and the winding temperature is evenly distributed. The cooling energy requirements are low. Reliable bearings long service life and low maintenance The antifriction bearings are reliable and precisely matched to the speed, load and other operating conditions. Sleeve bearings are also available for special applications. Well proven MICALASTIC insulation We use the optimum winding insulation: MICALASTIC offers high switching-, reversing- and winding voltage strength and therefore reliability and that over the long term. MICALASTIC has proven itself worldwide under the toughest operating conditions: In extreme coldness heat or moisture, in chemical plants or power stations. Resistance thermometer for additional protection When things get too hot, H-compact PLUS reacts immediately: Resistance thermometers integrated in the stator winding as standard, provide the perfect overload protection. Life cycle costs H-compact PLUS motors are energy-saving, require low maintenance and operate reliably over their long service lifetime. This is an investment which pays back after just a short time. H-compact PLUS motors are environmentallyfriendly and are recyclable up to approximately 98 %.

Alternatively, there is a single conductor connection for fully insulated cable connectors up to 400 A. Basis frame for all degrees of protection and type of cooling 6 7

6 Service and support worldwide: We are available to answer all your questions You are on the right track if you select the right motor because everything runs smoothly right from the start. This is because we think that quality also involves service: Our personnel will support you in implementing the optimum motor concept. And because service later on fulfills all of our customers' demands. In 130 countries of the world You can always rely on Siemens. We are one of the world's leading companies in the Electrotechnical branch, and we are close to our customers everywhere: Around the globe, in 130 countries and in more than 450 cities our support is always close to you. And you will always be able to find somebody you can actually speak to. Optimum customer orientation Our organisation is consequentially orientated to our customers' requirements. We consider us as partners for our customers. Support when selecting the optimum motor concept up to services after the motor has been shipped, such as maintenance, troubleshooting and, and, and.
