A woundrotor motor also known as slip ringrotor motor is a type of induction motor where the rotor windings are connected through slip rings to external resistance adjusting the resistance allows control of the speedtorque characteristic of the motor woundrotor motors can be started with low inrush current by inserting high resistance into the rotor circuit as the motor accelerates.
Aac is the next evolution in soft starter technology using aac the soft starter learns your motors performance during start and stop then adjusts control to optimize performance the soft starter estimates the motors speed throughout each aac start and stop and adjusts power to the motor.
