In Figure, the path of magnetic flux is shown when stator coils carry currents and a
ferromagnetic rotor is suitably placed in the magnetic field. The flux will always try to follow
minimum reluctance path, i.e., it has a tendency to shorten its flux path. Here rotor will experience
a torque in the anticlockwise direction and its axis will coincide with stator pole axis. This torque
is called alignment or reluctance torque. This is produced only when the reluctance seen by the
working flux changes with the rotor movement. Reluctance torque. | |
