When starting three phase induction motors which of the following starting methods will immediately apply rated voltage to the machine?

Which starting method is the best method of induction motor?

Direct on Line Starting Method

In this method we directly switch the stator of the three phase squirrel cage induction motor on to the supply mains. The motor at the time of starting draws very high starting current (about 5 to 7 times the full load current) for the very short duration.

What are the types of starter?

Types of Magnetic Motor Starters

  • Direct-On-Line Starter. The direct-on-line starter is the simplest form of motor starter, other than a manual starter. …
  • Rotor Resistance Starter. …
  • Stator Resistance Starter. …
  • Auto Transformer Starter. …
  • Star Delta Starter.

Why starters are used in induction motor?

Let us study in detail why starter is required for an induction motor. At starting time, the speed of the motor is zero and slip is at its maximum i.e. unity. So magnitude of the rotor induced emf is very large at start.
