Starting of several motors When an optimization of the project is to be done, multiple current of all motor together. – Soft starter selected should be capable of handling starting 11/07/2019 · Thus from the working principle of three phase induction motor, it may be observed that the rotor speed should not reach the synchronous speed produced by the stator. If the speeds become equal, there would be no such relative speed, so no emf induced in the rotor, and no current would be flowing, and therefore no torque would be generated.

Soft starter in induction motor is used for blower, mixer, grinder, pump and other industrial usage. The basic concept of a soft starter in a three phase induction motor is by setting the incoming voltage to control the initial current and the torque used. Soft starter is designed using NN (neural network) and 3. Star-delta starter: This method is used in the motors, which are designed to run on delta connected stator. A two way switch is used to connect the stator winding in star while starting and in delta while running at normal speed. When the stator winding is star connected, voltage over each phase in motor will be reduced by a factor 1/(sqrt.
