A Synchronous motor for power factor correction operates at which condition | Electrical Machines MCQ#20

by

A Synchronous motor for power factor correction operates at which condition:

  1. No load and no excitation
  2. Half load and full excitation
  3. Full load and no excitation
  4. No load and overexcited

Correct answer: 4. No load and overexcited

An overexcited synchronous motor operating at no load can be used to supply reactive power in the circuit.
