Question

Select the proper Problem-solution combination during Universal motor modified from the DC Series Motor.

Problem
Solution

1. Its efficiency will poor due to hysteresis and eddy current losses
1. Use – Compensating Winding

2. Power factor of the motor is low due to inductive reactance of the field and armature windings
2. Use – Laminated Core Structure

3. The sparking at the brushes will be excessive due to the effect of armature reactance
3. Use – Reduced number of turns & Increase it Thickness
