The features are:

  1. Speed control and braking operation are available from zero speed to above base speed.
  2. During transients (starting, braking and speed reversal) the operation can be carried out at maximum torque with reduced current giving a good dynamic response.\
  3. Copper losses are low, and efficiency and power factor are high as the operation is restricted between synchronous and maximum torque point at all frequencies.
  4. Drop-in speed from no load to full load is small.
