Motors for Metal Rolling Mills Features and Benefits

Design Feature

• High strength coil head bracing and connections will withstand magnetic

forces under frequent reversing direction of rotation.

• 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.

• Detailed analysis of the electromagnetic field patterns and ventilating

airflows yields an optimized motor design with maximum cooling and

efficiency.

• Application of TMEIC vacuum pressure insulation (VPI) system and

very large autoclave can process any size of stator.

• Static and dynamic strength analysis of stator, frame, rotor, shaft and 

bearings.

• Selection of appropriate forged steel shaft with high tensile strength.

Customer Benefit

• High reliability and longevity with no unplanned production interruption.

• Lower energy expenditure.

• High reliability and longevity with no unplanned production interruption.

• High strength of insulation required for special operating duty and steel

mill environment will ensure long operating life.

• Greater mechanical strength to sustain the multi-directional forces, 

vibrations and electro-magnetic forces ensure continuous operations.
