Star connection of motor

The phase voltage is lower than line voltage in star connection , so the motors or drives connected in star connection runs at lower speed as compared to delta connection. Open or close star delta starter with contactors, timers,switches for motor starting, where in motor windings connected in star ,then in delta starter, types. Star Delta Starter Power Wiring कैसे करे ? Electric Guru - Duration: 5:32. Motors supplied by high voltage like 6.

V have Stator connected in Star configuration.

The reason behind this is technical while making the .

Voltage reduction during star -delta starting is achieved by physically reconfiguring the motor windings as illustrated in the figure below. During starting the motor windings are connected in star configuration and this reduces the voltage across each winding 3. Watch induction motor star and delta connection. To wiring the motor connection for star delta starter,the important thing that we must fully understand is about the basic of STAR DELTA MAGIC TRIANGLE. Let me give the features of both the winding and when it is likely to be used Star Winding 1. Delta connection reduces the current but bring the voltage to the desired . Star connection is preferred for long distance power transmission because it is having the neutral point.

In this we need to come to the concept of balanced and unbalanced current in power system. Due to the low cost and high availability . How does an Induction Motor work ? Why LT motors are delta connected and HT motors are star connected ? So insulation required in case of HT motor is less. In star , phase current is same as line current. The question, I presume, is can you do it without damage. Read the motor winding max voltage from the rating plate.

It can take 6–times of rated current during start. Induction motors are designed very rugged and they can even take this amount of current. But if so high current is taken by induction motors during start, following . Y connected motor will work with the neutral wire disconnected and insuleted.

Now in the below diagrams, Three phase Motor will rotate . Contactor coil Cand Timer coil (I1) is energized at once and the motor winding then connected in Star. When Cis energize its auxiliary open links will be closed and vice versa (i.e. close links would be open). Thus CContactor is also energized and Three Phase Supply will reach to the motor.
