- Construction is simple and robust.
- Rotor carries no windings, no slip rings, no brushes, less maintenance.
- There is no permanent magnets.
- Ventilating system is simpler as losses takes place mostly in the stator.
- Power semiconductor switching circuitry is simpler.
- No shoot through fault likely to happen power short circuits.
- Developed torque does not depends upon the polarity of current in the phase winding.
- The operation of the machine can be easily change from motoring mode to generating mode by varying the region of conduction.
- It is possible to get very high-speed.
- Depending upon the requirement T-w characteristics can be achieved.
- It is the self-starting machine.
- Energy stored in the phase winding is fed back to the supply through the feedback diodes during off period.
