Describe working principle of Shunt motor. Also give the differences between series and shunt motor.

Answer»

Difference between DC series and DC shunt motor:

S.no.	Parameter	DC Series motor	DC Shunt Motor
1	Connection of field winding with armature	Field is in series with armature	Field is in shunt with armature
2	Type of starter	4 point	3 point
3	Torque	high	low
4	Application	Electric trains, conveyers	Machine tool, printing, paper machine

Working principle of shunt motor:

When we apply a voltage to the motor a current produced in the armature and a strong magnetic field, by the way, produced this field interacts with the magnetic field and makes the armature rotates. When the armature rotates it produces a back EMF this EMF opposes the armature voltage and reduces the armature current if we increase the motor load the armature will rotate slowly and the back EMF will reduce.
