SM-ML SERIES
STEEL MILL HEAVY DUTY DC MOTORS (MILL MOTORS)
General
Steel mill heavy duty DC motors series SM-ML (MILL motors) have been designed for use in variable speed drives for heavy
duty applications. Motors have skewed armature slots to ensure low torque ripples at slow speed. Motors are available up to
17400Nm.
These motors exactly meet A.I.S.E. Standard requirements in terms of:
outputs (torques, speeds, powers, etc.)
overall and coupling dimensions
domensions and positioning of ventilation openings
so they are fully interchangeable to whatever DC motor of same frame size manufactured in accondance with A.I.S.E.

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
withstand without any problem to 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 kinf of thermal protection (Pt100, PTC, etc.)

STEEL MILL HEAVY DUTY DC MOTORS (MILL MOTORS)
Some word about SICMEMOTORI
SICMEMOTORI has been designing, manufacturing and selling DC motors since 1962, at first as a Division of SICME (producing
wire enamelling plants) and then, from 1967, as an independent company; from the beginning its products have been well
received because of their quality and reliability.
SICMEMOTORI products have followed the complete evolution of DC motors technology, and today SICMEMOTORI is one of
the leading manufacturers of DC motors in Europe. More than 85% of SICMEMOTORI DC motors are directly or indirectly
exported.
The Company is located in Turin, in the North-West part of Italy, in one of the most industrialized area of Europe. The Company is
organized on the principles of “lean production” and “learning organization”. The integrated IT system of the Company controls all
its activities, from order entry to the delivery of materials. Production is managed by a modern “MRP” system, and all operations
are controlled by bar code; production is carried out in two plants, with a total surface area of approximately 10,500 sqm.
Customers are allowed, via a password, to enter the company’s IT system, to check status of their own orders.
Motors are produced according to ISO 9001-2000 quality assurance system.
Due to its long history, SICMEMOTORI has achieved a very high level of experience in the most severe applications, from iron &
steel mills to rubber mixers (Banburies), from cranes & hoists to chairlifts & funiculars, to cement factories, mining industries,
paper & print machines, sugar centrifuges, plastic extruders and film process, etc..
SICMEMOTORI products can be found all over the world; the after sales service is provided by a network of authorized repair
shops, selected and certified by SICMEMOTORI (the updated list is on SICMEMOTORI web site www.sicmemotori.com).
SICMEMOTORI is member of EASA.
Notes:
Customers can determine whether a specific product is suitable for their needs and are thus responsible for the selection, use
and results obtained by any product showed in this catalogue. The information contained in the present catalogue does not
guarantee the characteristics for the use.
The products listed in this catalogue are exclusively designed and built for industrial purposes.
For particular cases in NON-industrial environments, or where other types of protection must be provided (for example against
contact with children fingers, etc.), these guards or additional protections must be realized by the customer.
Any non-observance of the rules for installation, use and maintenance or any modification/tampering with the motor makes the
guarantee rights invalid and exempts SICMEMOTORI from any responsibility.
All data and indications shown in this catalogue have to be considered only as a guideline.
Any use of the motor differently from the specifications indicated in this catalogue does not involve any liability for
SICMEMOTORI as manufacturer.
SICMEMOTORI reserves the right to modify at any time and without notice the data, the technical characteristics, the
dimensions, the weights and the illustrations.
SICMEMOTORI refuses all responsibility for direct or indirect damages caused by possible errors and/or omissions in the
present catalog.
The reproduction, even in part, of the present catalog must be authorized in writing by SICMEMOTORI.
WARNING
The motors and the electrical devices feeding them are electrical components installed on machines and industrial
systems subject to high voltage. During operation, these components can be dangerous since they are live and have
non-insulated and rotating parts. Therefore, they can be extremely harmful to personnel and objects if the instructions
for the installation, the use and the maintenance are not respected.
The motors are always supplied complete with the installation, use and maintenance instruction manual. It is
necessary to read and understand all the information contained before proceeding to connect and to start up the
installation.
If the above mentioned documentation is lacking, please request a copy to SICMEMOTORI.
CAUTION
All information, data, drawings given in this catalogue are of a purely indicative nature and may be changed without
prior notice. SICMEMOTORI shall not be held responsible if the products illustrated herein are used outside their
limits of the specifications given.
