Asynchronous crane-metallurgical motors 4MTKU

To order
 
 

Three-phase asynchronous motors with squirrel-cage rotor designed to drive hoisting and transport mechanisms and are used to complete gantry and bridge cranes, crane-beam, truck cranes in metallurgy, in construction, in transport and other industries.
Climatic performance: U1, T1, УХЛ1, 01 according to GOST 15150-69.
Installation version:
– IM1001, IM1002, IM2001, IM2002 with cylindrical shaft ends;
– IM1003, IM1004, IM2003, IM2004 with tapered shaft ends.
Depending on the installation method, the motors are of the following design:
– on paws (first digit 1), combined
– flange and feet (first digit 2),
with one (last digit 1,3) or two (last digit 2,4) output shaft ends.
On request, the motors can be manufactured for other mounting designs.
Degree of protection: IP54 according to GOST 17494-87, at the request of IP55 and higher.
Cooling method: IC411 ( own fan);
Vibration class: 2,8 according to GOST 20815-93.
Voltage: 220/380, 380/660 In at f = 50Hz or 60Hz.
Insulation class: “N” according to GOST 8865-87.
Group of operating conditions in terms of the impact of mechanical environmental factors – M3. Manufacturing with a group of mechanical strength different from M3 by agreement.
Design features: To protect the stator windings from overheating, the motors are, on request, equipped with CT14-2 PTC thermistors for an operation temperature of 165ºWITH, or bimetallic thermal switches, operating on the principle of opening a bimetallic contact.
Water device K-3-II (with terminal panel and two unions).
Working hours: intermittent S3 – PV40% according to GOST 183-74. Motors can operate in other modes: S3 – 15, 25, 60, 100%, short-term S2 – 30 and 60 min. Motors can also be used in continuous duty mechanisms.
During operation, the motors provide operation in the modes of electric braking and opposition, as well as in high (up to +70ºWITH) ambient temperature (metallurgical or pipe-rolling shop). 
Designation of structural modifications:
B – PTC thermistors built into the stator winding;
B1 – bimetallic thermal switches built into the stator winding;
Electric motors are produced according to TU 31.1-32832237-027:2009.
