Description
Steel Mill Duty Motors from Sicme Motori.
Manufacturer: Sicme Motori
Range: SM/ML Series Heavy Duty Industrial DC Mill Motors
Typical applications:
- Steel Mills
- Rolling Mills
- Aluminium Mills
- Mining
Sicme Motori steel mill heavy duty DC motors series SM-ML (MILL motors) have been designed for use with variable speed drives in heavy duty applications such as steel mills and rolling mills. The DC Motors have skewed armature slots to ensure low torque ripples at slow speed.
The Sicme Motor SM-ML heavy duty industrial Mill Motors are available up to 17400Nm and are in use in mining and Mill applications around the globe. Our extensive DC Motor and Drive experience means custom motors are no obstacle, so if you are looking for a Mill Duty motor for a new application or are wanting to upgrade an existing installation or simply have a motor on hand that can be dropped in as required, we have the know how to make it happen.
These motors exactly meet A.I.S.E. Standard requirements in terms of:
– outputs (torques, speeds, powers, etc.)
– overall and coupling dimensions
– dimensions and positioning of ventilation openings
so they are fully interchangeable with a DC motor of same frame size manufactured in accordance with A.I.S.E. Standards

Terminal box:
- No terminal box, loose hanging leads as standard (right side facing DE)
Thermal protection:
- N°. 1 thermoprotector on auxiliary windings as standard
Full speed, half speed and quarter speed design available.
Motor design: SM 802-804 series
– Steel fabricated, split frame
– Heavy-duty roller bearings with easily removable bearing housings
Motor design: ML 806-818 series
– Fully laminated stator core, no split frame
– Compensating windings (as option on frames 806-808-810, as standard on frames 812-814-816-818)
– Heavy-duty roller bearings
Fully laminated machines have the relevant advantage to accept extremely high current gradients (200In/sec). These motors are built to withstand frequent and extremely rapid current pulses, arising from static converters.
Options available
– 1 tapered shaft end only (IM1003)
– 1 (IM1001) or 2 (IM1002) cylindrical shaft ends
– terminal box
– different kind of thermal protection (Pt100, PTC, etc.)
– tachometers, pulse generators, overspeed switches
– anticondensation heater- brakes
– etc.
Typical installations include:
- Steel Mills
- Rolling Mills
- Aluminium Mills
- Mining
