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. |

| 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. |
