If I2 be the armature current, then speed of a D.C. shunt motor is_______________?
Correct answer: A. independent of Ia
- A. independent of Ia
- B. proportional to la
- C. varies as (Ia)
- D. varies as la
Explanation
In a shunt motor, the field flux is nearly constant, so speed is approximately independent of armature current. Armature-current changes mainly produce a small speed drop due to armature resistance.
