Mill duty DC electric motor
7.5 - 187 kW, 230 - 500 V T-T ELECTRIC

We propose a series of mill duty dc motors between 7.5 and 187 kW (10-250 HP) in A.I.S.E. frame sizes 802 to 818. T-T Electric mill duty motors conform to A.I.S.E. No.1-1991 in regards to output and physical dimensions, and are therefore interchangeable with any other brand of A.I.S.E. standard motors of the same size.
The mill duty motors are suitable for operation with the latest generation of thyristor convertors. The fully laminated stator design of the motors permits a very high rate of change of current, meeting the steel mill requirements of high dynamic response and repetitive overload capability. The motors are fully compensated, offering the benefits of enhanced commutation margin in a wide constant power speed range, and good stability independently of motor load. This design, however, does not allow for a split stator frame, as stipulated by the A.I.S.E standard.
