. Mechanical design General The roller table motors supplied by ABB are squirrel cage motors which are specially designed for use with frequency converters. Robust in construction, the motors are fully sealed to withstand the tough conditions in rolling mills. The motors are low speed units intended for direct connection to rollers. The pole number and frequency can be selected, avoiding the need for gearboxes and therefore saving on maintenance costs and increasing the overall efficiency of the drive. Assembly dimensions and shaft heights are in accordance with IEC 60072-1. The normal motor mounting position is B3/IM1001. Flange mounting (IM B5/IM3001) is possible for frame sizes 180-250 on request. ABB Roller table motors The enclosure of the motors is protected to IP55. Higher degrees of protection, up to IP 65, are also available. If required, the stator frame of M3RP motors can be pressurized with air to prevent any ingress of water or dust. ABB offers roller table motors in sizes 180 to 450, with smaller sizes available on request.

ABB Roller table motors Roller table motors Technical data for totally enclosed squirrel cage three phase motors IP 55 – IC 410 – Insulation class F, temperature rise class B Motors and frequency converters - solutions for rolling mills that incorporate ABB's wealth of application know-how ABB Roller table motors ABB meets the demands of the rolling mill environment by combining the expertise of two areas within the Group. By bringing together squirrel cage motors from ABB Motors and frequency converters from ABB Drives, ABB can supply electrical drive systems that are tailored to the needs of the industry. ABB Motors has been developing and growing for over 100 years and is today one of the world’s leading manufacturers of low voltage induction motors. It supplies a full range of industrial electric motors, meeting the needs of most applications with virtually any power rating. At the same time it provides solid value and commitment to its customers through unrivalled service and back-up. ABB Drives is the leading manufacturer of AC and DC drives for all types of demanding applications. For low voltage multimotor systems, ABB supplies AC drives up to 5600 kW. Through its unrivalled experience in AC and DC drive design, manufacture, installation and commissioning, ABB has acquired a vast reserve of know-how for specific applications. ABB Roller table motors One of these applications is the rolling mill, where the extremely harsh environment and tough production process demand the best in AC drive technology. An example of this superior technology is ABB’s DTC controlled ACS800 multidrive frequency converter, which has received excellent feedback from users in roller table applications. ABB has invested heavily in research and development, ensuring that each generation of induction motors and frequency converters keeps pace with the rising needs of the metal industry. The products are known for their efficiency, robustness and reliability – characteristics which combine to deliver the maximum possible value for customers. ABB Roller table motors The motors feature a number of mechanical solutions that have been designed for the extreme conditions found in rolling mills. The standard shaft end is of cylindrical construction. Conical shaft ends, as well as double shaft extensions, are available on request. Robust, die-cast aluminum squirrel cage rotors, which are highly wear-resistant, are used throughout the motor range. The rotor slot design is optimized for frequency converter applications. The frames and bearing end shields are made of cast iron. Spheroidal graphite cast iron is used as standard in frame sizes 355-450, and is available on request for smaller frame sizes. All fixing screws and bolts are locked. The motors are totally enclosed, frame cooled motors, with no external cooling fan, in accordance with IEC 60034-6, IC 410. The stator frames have crosswise vertical cooling ribs, allowing optimum heat flow away from the motor surface. A water-cooled version is available on request.

ABB Roller table motors Roller table drives Roller tables incorporate a number of motors, the speed of which can be steplessly controlled by one or more frequency converters. The rolling mill environment places severe stress on roller table drives. As plates and billets travel along the roller table at high speeds, the motors driving the rollers are subjected to high torque loads. At the same time, the reliability of the drive system is constantly threatened by the high ambient temperature, humidity, and the risk that fine dust particles from the process could infiltrate the motors. To meet these rigorous demands, ABB has developed its Roller Table AC Drive System, which comprises the new, robust M3RP induction motors, together with ABB frequency converters. ABB Roller table motors The totally enclosed construction of the M3RP induction motors renders them immune to the ingress of moisture and dust. The power factor of ABB frequency converters with IGBT supply units is 1.0 under any load conditions. Together the motor and frequency converter provide a competitive solution, with high availability and minimal maintenance costs.
