How much KW range can be use star-delta starter?
The use of a star delta starter is for motor control only and not resistive heating loads. This type of starter is used to dampen the inrush current by using a lower voltage to start the motor.
Why you are using star connected induction motor and delta connected induction motor?

Star delta starter for 3 phase induction motor?
how will you start 3phase inuction motor using star delta stater
The speed of an electric motor can be controlled by?
By using the star- delta starting methodBy using variable rhoestatsBy using auto transformers
What are the advantages of using star connection?
The inrush current is reduced. This is the reason for star delta starters. Motor starts on star and after about 10 to 15 seconds, depending on the load of the motor, it switches to a delta configuration to run.
What are the types of motor controls?
motor can be control by using variable frequency drive
Speed control of motor using SCR?
An SCR chip is commonly used to control the speed of a motor. The speed is controlled using an AC circuit and phase angles.
Why using on motor star delta starter?
because at the starting the induction motor drawn a heavy current thats why we use starter to increase the starting resistance of the induction motor!
How many contactors using in star connection of motor?
two contecter <<>> There are three contactors used in a Star Delta configuration.
What is the difference of a star or delta connection on motor terminals?
230/400 V These motors can be connected in star to a mains of 400 V between the phases (see figure 1). figure 1 Star connection 400/695 V These motors should be connected in delta to a mains of 400 V between the phases (see figure 2).
Future scope of dc motor speed control using rf?
The DC motor speed control has a scope of four speeds. The control speeds include; high, medium, low, and off.
How do you introduce feedback circuit in dc motor speed control?
By using your brain
