Electric Star Delta Wiring Diagram

A Star-Delta starter is an electromechanical device used to start and control the speed of a three-phase induction motor. This starter employs the star-delta (Y-Δ) method for starting the motor, which involves changing the motor's winding connection from a Star configuration to a Delta configuration once the motor reaches a certain speed.

This is the reduced voltage starting method. 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.

The advantages of using a star delta starter are: Simple to wire and implement. Torque and current are controlled to a safe level. It only will draw around 2 times the full load capacity (FLA) of the motor when starting - compared to 5 times when the motor is connected in delta. Star delta starter circuits reduce the current when starting to.

The manual control procedure for the star-delta starter without timer is relatively simple. It involves the following steps: Initial State: The motor is at rest, and the windings are disconnected. Star Connection: Press the "Start" button or close the start contactor. This connects the motor windings in a star configuration.

2. Delta connection. In order to make a delta connection, we connect the ends of coil U1 to the end W2, coil V1 to U2 and finally, the end of coil W1 to V2. The following image shows the delta connection scheme in an electric motor. The representation in an electrical diagram would correspond to the following image.

3-P MCCB is used to protect the combination of star delta and reverse / forward starter circuit from overload and short-circuit. 2-P MCB is used to protect the control circuit. The main contactor "K1" is used to operate the motor in normal i.e. forward direction. The contactor "K2" is used to runs the motor in reverse direction.

Star Delta Wiring diagram from The Motor Control Warehouse I'm going to use the old Red Yellow Blue colour coding for the phases simply because I think it's easier to see. However, we will look briefly at other colour codes later in the article. Three phase motors are used in almost every commercial and industrial building.


Wiring Diagram Of Star Delta Motor Wiring23

In star delta starting an induction motor is connected in through a star connection throughout the starting period. Then once the motor reaches the required speed, the motor is connected through a delta connection. A star delta starter will start a motor with a star-connected stator winding.

Star delta starter is the popular method to start a large induction motor at a reduced voltage. Star delta starter means two separate stat of starting. First, the motor starts with a star connection and when it reaches up to 75% to 85% of its full load speed, the motor runs in delta connection. When the motor starts without a Star-Delta starter
