MARK ELEKTRIKS Gultekdi, Pune, Maharashtra

Torque motor is basically an induction motor; but with drooping curves. Torque motor specifies Stall (Lock) torque and no load speed on the name plate. A standard squirrel cage motor tries to maintain the speed as it is loaded while a Torque motor will drop in speed as it is loaded. MARK ELEKTRIKS developed Torque motor as import substitutes in 1971 and has since then supplied over 50000 Torque motors for winding for various other applications.   Application Motors for winding of following materials are available HDPE Tapes, Monofilament- yarns, Box strapping All types of extruded plastic films Rubberised Fabrics, textiles 20 to 100Hz, 50 to 250 V, flange mounting type. Copper Wires from 8 SWG to 43 SWG. S.S. Wires/ M.S. Wires Strips of Copper, Mild Steel etc.  ‘MARK’ make TORQUE MOTORS are used in WIRE INDUSTRY for Wire Enamelling Machines from 14 SWG to 42 SWG (Both Horizontal & Vertical Type) Wire Stranding & Bunching Machines Wire Drawing Spooling Machines Paper Covered Conductors (Round & Strip) etc For Wire Drawing Spooling, Bunching, Stranding Machines 3 HP, 1.5 Kg-M, 1400 RPM, 132 Frame, 3 Phase, SPFV with Blower 5 HP, 2.5 Kg-M, 1400 RPM, 132 Frame, 3 Phase, SPFV with Blower 7.5 HP, 3.5 Kg-M, 1400 RPM, 160 Frame, 3 Phase, SPFV with Blower 10 HP, 5.0 Kg-M, 1400 RPM, 160 Frame, 3 Phase, SPFV with Blower 15 HP, 7.5 Kg-M, 1400 RPM, 180 Frame, 3 Phase, SPFV with Blower 20 HP, 10 Kg-M, 1400 RPM, 180 Frame, 3 Phase SPFV with Blower Range Three Phase from 3 kg-cm (0.03 kg-m) to 2000kg-cm (20 kg-m) Single Phase from 0.7 kg-cm to 35 kg-cm.

'MARK ELEKTRIKS' can also supply one to one replacement to imported motors. Geared Torque Motors with planetory gearboxes are also available. For ganged application such as HDPE Tapes/ Monofilament Yarns etc. one common variac can control all the Torque Motors. This is possible because we manufacture Torque Motors (Motors for winding) for such applications within a close tolerance with similar T/ N Curves.   n Case your requirement is different then you can send us following details and we can design the torque motor for your requirement : SWG Range of Wire (Min. & Max.diameter of Wire) Spool Size – Barrel Dia. X Flange Dia. (Please give these details separately if you want to use different sizes of spools) Max.Weight of Wound Spool with Wire Min. & Max.Line Speed of Wire to be wound in meters per minute Quantity required

Speed of Stall Torque Motor drops as it is loaded and reaches to zero as seen from the graph. After reaching zero speed, if the shaft of Torque Motor is rotated by force in opposite direction of normal rotation then the Torque Motor tries to resist it. (Please see graph below X-axis, which shows T N curves at different voltages) This means that when an energized Torque Motor is driven by an extended source against normal rotation it exerts an almost constant lacking torque on this extended source.

They are extremely useful in applications where speed synchronism between different machines is required e.g. Synthetic fibre industry, glass making machinery, textiles etc. For spinning metering pump 0.321.6 hp , 4 pole, 16-80 Hz , 54-220V, Foot mounting NEMA 182 frame,For feed roll 5KW ,1500 rpm, 4 pole , 220V50 Hz, suitable for frequency 25 to 130 Hz and 110V to 572V, flange mounted,112 frame.

Speed of Stall Torque Motor drops as it is loaded and reaches to zero as seen from the graph. After reaching zero speed, if the shaft of Torque Motor is rotated by force in opposite direction of normal rotation then the Torque Motor tries to resist it. (Please see graph below X-axis, which shows T/ N curves at different voltages) This means that when an energized Torque Motor is driven by an extended source against normal rotation it exerts an almost constant lacking torque on this extended source.   Application   One main application of these Stall Torque motors is Cable reeling drums (Motorised Cable Reeling) The typical property of Stall Torque Motor is used in unwinding application of cable reeling drums. Motorised Cable Reeling Drums (C.R.D.) are used to supply electrical power to moving equipment like Stackers, Reclaimers, Trippers etc. in Steel Plants, Cement Plants, Power Stations, Ports/Docks etc. Cable Reeling Drums are driven by Stall Torque Motors through Gear-Boxes of required ratios. Cable Reeling Drums rotate in both directions depending upon application ( i.e. whether cable is paid-off or is reeled in). We are supplying motors for cable reeling drums (Motorised Cable Reeling) as per Mark standard and also direct replacement for Demag / AKH / other Chinese manufacturers.   Types Mark Elektriks manufactures Torque Motors since 1971 for various applications.

After reaching zero speed, if the shaft of Torque Motor is rotated by force in opposite direction of normal rotation then the Torque Motor tries to resist it. (Please see graph below X-axis, which shows T N curves at different voltages) This means that when an energized Torque Motor is driven by an extended source against normal rotation it exerts an almost constant lacking torque on this extended source.

Energy resources worldwide are depleting at very high rate and energy conservation is becoming the norm of the day. With stricter energy consumption norms worldwide Energy Efficient Motors are manufactured in IEE efficiency classes (I,II,III) as per customer requirement. Energy efficient motors, also called premium or high- efficiency motors, are 2 to 8% more efficient than standard motors. Motors qualify as"energy-efficient" if they meet or exceed the efficiency levels listed in the National Electric Manufacturers Association's (NEMA's) MG1-1993 publication. Energy efficient motors owe their higher performance to key design improvements and more accurate manufacturing tolerances. Lengthening the core and using lower-electrical-loss steel, thinner stator laminations, and more copper in the windings reduce electrical losses in Energy efficient motors. Improved bearings and a smaller, more aerodynamic cooling fan further increase efficiency in the design of Energy efficient motors Energy efficient motors should be considered for all new installations, replacement of failed motors, or as spares. Energy efficient motors are frequently a cost-effective alternative to rewinding, and are sometimes an economic substitute for well-functioning motors in high-duty applications.
