When V is the applied voltage, then the breakdown torque of a synchronous motor varies as_________?
Correct answer: A. V
- A. V
- B. V312
- C. V2
- D. 1/V
Explanation
For a synchronous motor with constant excitation, the maximum or breakdown torque is proportional to the applied voltage, as shown by Tₘₐₓ ∝ VE/Xs. Therefore, it varies directly as V, not V².
