Applications of DC Shunt Motor

Applications of any motor depend mostly on its speed torque characteristics

As you can see in above image, even though output torque of DC shunt motor increases comparatively speed doesn’t fall much.
DC shunt motor is also called as constant speed motor.
In other words, if we assume that the supply voltage is constant then flux also becomes constant. At the rated speed the back emf also becomes nearly constant if the load is same.
The various applications of DC shunt motor are in
  1. Lathe Machines,
  2. Centrifugal Pumps,
  3. Fans,
  4. Blowers,
  5. Conveyors,
  6. Lifts,
  7. Weaving Machine,
  8. Spinning machines, etc.
So you will find application of DC Shunt motor wherever constant speed operation is required.
