Question

what is star to delta conversion , don't copy it from goggle, otherwise u have to pay for it​

Answer 1

Explanation:

• The Star Delta Starter is a very common type of starter and is used extensively as compared to the other type of starting methods of the induction motor. A star delta is used for a cage motor designed to run normally on the delta connected stator winding. The connection of a three-phase induction motor with a star delta starter
• When the switch S is in the START position, the stator windings are connected in the star as shown below
• When the motor picks up the speed, about 80 percent of its rated speed, the switch S is immediately put into the RUN position. As a result, a stator winding which was in star connection is changed into DELTA connection now. The delta connection of the stator winding in shown in the figure below.
