Why is star delta starter preferred with an induction motor?

Star-Delta starter is an electrical motor starting device, generally uses in big size motor to overcome high motor currents during starting. Star and Delta means here 2 separate states of

PLC Tutorial Star delta starter for induction motors

If the motor is too heavily loaded, there will not be enough torque to accelerate the motor up to speed before switching over to the delta position STAR DELTA connection Diagram and Working principle Descriptions: A Dual starter connects the motor terminals directly to the power supply. Hence, the motor is subjected to the full voltage of the power supply. Consequently, high starting current

A Comparison between Star and Delta Connected Induction

In starting motor gets 3 to 4 times more current then its normal current. So we use star delta starter to limit the starting current of the motor with the help of star circuit.when motor will run in the normal position so the circuit of the motor will change to delta circuit with the help of centrifugal switch.

Understanding the basic principles behind VFD operation requires understanding the three basic sections of the VFD: the rectifier, dc bus, and inverter. The voltage on an alternating current (ac) power supply rises and falls in the pattern of a sine wave (see Figure 1). When the voltage is positive, current flows in one direction; when the voltage is negative, the current flows in the opposite

Siemens India Ready to use motor Starters

As i have experience with some soft starters, i found that the starting current of the starter is more than star-delta starter. Can you please guide me why it is so? i will be happy if i will get reply on it. for ex. If star delta starter is taking 33% starting current of the RLA, then for the same motor softstarter is taking 45 to 50 % dtarting current on it. Please explain.
