Torque Motors For Winding Applications
What is a torque motor ?
Torque motor is basically an induction motor; but with drooping curves. It 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 them as import substitutes in 1971 and has since then supplied over 50000 torque motors for various winding applications.
Application of Torque Motors
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

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.
RPM:From 500 RPM to 3000 RPM (12 pole to 2 pole)
 
Construction
Available in IEC frame sizes as well as modified mechanical frames for special applications. '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 for such applications within a close tolerance with similar T/ N Curves.
