An electronic soft starter is used in full-speed induction motor applications, like a direct on-line starter or a Wye-Delta starter. However, as with a variable-speed drive, it is possible to continuously and frequently start and stop the motor.
These capabilities make of the electronic soft starter the best choice for starting motors in a very wide range of applications. 90% of all the induction motors are used in nominal speed applications where the possibility of adjusting the motor speed ads very little or no value to the process.
