Motors for Metal Rolling Mills

AC adjustable speed motor drive systems are the preferred technology for new rolling mill installations and modernization projects.

TMEIC designs and manufactures two types of AC solutions for this purpose.

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

Superior efficiency
Robust frame and shaft construction
Less demand for maintenance
High degree of control and responsiveness
Great capacity for acceleration and deceleration.
Greater flexibility for extreme operating conditions
