In D.C. shunt motors as load is reduced
A. The speed will increase abruptly
B. The speed will increase in proportion to reduction in load
C. The speed will remain almost/constant
D. The speed will reduce
Answer: Option C
Solution (By Examveda Team)
In a D.C. shunt motor, the field winding is connected in parallel (shunt) with the armature winding.Since the field winding is connected directly across the supply, the field current remains nearly constant regardless of the load.
As a result, the magnetic field produced is stable, and any small change in armature current due to load variation has minimal effect on the speed.
Therefore, even when the load is reduced, the motor speed does not change significantly.
This is why D.C. shunt motors are widely used where constant speed is required.

In a dc shunt motor if the load is reduced then speed will be slightly increase
