AC adjustable speed motor drive systems are the preferred technology for new rolling mill installations and modernization projects.<\/p>\n\n\n\n

TMEIC designs and manufactures two types of AC solutions for this purpose.<\/p>\n\n\n\n

    \n
  1. Salient pole synchronous motors that meet the high power and torque demands of a hot strip mill, as well as roughing and finishing stands.\n
      \n
    • Excellent torque characteristics<\/li>\n\n\n\n
    • Superior efficiency<\/li>\n\n\n\n
    • Unit power factor<\/li>\n\n\n\n
    • Easy to control<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Squirrel cage rotor motor applied to medium power requirements of reels and stands.\n
        \n
      • Extremely robust construction<\/li>\n\n\n\n
      • Excellent torque characteristics on ultra-low speed rolling applications<\/li>\n\n\n\n
      • Constant power output throughout field weakening range<\/li>\n\n\n\n
      • Meets NEMA MG1 and JEM 1157 standards.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

        These motors have:<\/p>\n\n\n\n

          \n
        • Superior efficiency<\/li>\n\n\n\n
        • Robust frame and shaft construction<\/li>\n\n\n\n
        • Less demand for maintenance<\/li>\n\n\n\n
        • High degree of control and responsiveness<\/li>\n\n\n\n
        • Great capacity for acceleration and deceleration.<\/li>\n\n\n\n
        • Greater flexibility for extreme operating conditions<\/li>\n<\/ul>\n\n\n\n

          Motors for Metal Rolling Mills Features and Benefits<\/p>\n\n\n\n

          Design Feature<\/p>\n\n\n\n

          Customer Benefit<\/p>\n\n\n\n

          High strength coil head bracing and connections will withstand magnetic forces under frequent reversing direction of rotation<\/p>\n\n\n\n

          On squirrel cage motors, an optimal brazing between rotor bars and end rings will permit the motor to withstand the repeated acceleration, deceleration and reversal of rotation that is typical in this steel processing.<\/p>\n\n\n\n

          High reliability and longevity with no unplanned production interruption.<\/p>\n\n\n\n

          Detailed analysis of the electromagnetic field patterns and ventilating airflows yields an optimized motor design with maximum cooling and efficiency<\/p>\n\n\n\n

            \n
          • Lower energy expenditure<\/li>\n\n\n\n
          • High reliability and longevity with no unplanned production interruption.<\/li>\n<\/ul>\n\n\n\n

            Application of TMEIC vacuum pressure insulation (VPI) system and very large autoclave can process any size of stator.<\/p>\n\n\n\n

            High strength of insulation required for special operating duty and steel mill environment will ensure long operating life.<\/p>\n\n\n\n

            Static and dynamic strength analysis of stator, frame, rotor, shaft and bearings.<\/p>\n\n\n\n

            Selection of appropriate forged steel shaft with high tensile strength.<\/p>\n\n\n\n

            Greater mechanical strength to sustain the multi-directional forces, vibrations and electro-magnetic forces ensure continuous operation.<\/p>\n","protected":false},"excerpt":{"rendered":"
