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!
Star delta starter for 3 phase induction motor?
how will you start 3phase inuction motor using star delta stater
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).
What are the advantages of open end winding induction motor over conventional induction motor?
Open ended induction motor - i assume you are talking about split phase induction motor. With these motors old style speed controlling method using external resistors can be used. However this is now obsolete.
What is the starting method of synchronous motor?
There are 5 types of starting in induction motors: 1) resistance variable method 2) auto transformer method 3) slip ring induction motor method Squirrel cage induction motor using two types of starting methods 1.Direct on line starter 2.Star delta starter

What is a DC shunt motor?
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
What is a shunted motor?
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
What is the imporatance in using wyne delta motor control?
the important is contactor, timer, olr.....
The speed of an electric motor can be controlled by?
By using the star- delta starting methodBy using variable rhoestatsBy using auto transformers
What is the relationship between an induction motor and transformer?
In an induction motor, power is supplied to the rotor using a changing magnetic flux i.e. without any true conductive contact. Similarly, in a transformer, the power is transferred from the primary coil to the secondry one using a varying magnetic flux and the plates have no physical linkage. Hence, the similarity between an induction motor and a transformer is very basic i.e. they both use the phenomenon of electromagnetic induction to transfer power from one part to another.
Why are no starting components needed on three-phase motors?
Yes, by using a DOL Starter, which gives a controlled "soft-start" for the motor even though it is always connected in delta configuration.In this type of starting a 3-phase motor, full voltage is applied to the motor through relays and contactors. Its is the most common type of 3-phase motor starter used.DOL means Direct On-Line starter.
