What is the need of starter in 3 phase induction motor?

What is the purpose of starter in motor?

Introduction. Motor starters are one of the major inventions for motor control applications. As the name suggests, a starter is an electrical device which controls the electrical power for starting a motor. These electrical devices are also used for the purpose of stopping, reversing and protecting electric motors.

What starter motor do I need?

The need for a starter is dictated by the type of motor. Generally speaking, low-power motors do not require starters, although what’s considered low power may be debatable. For instance, small dc motors that run on low voltages (24 V or less) don’t require starters.

What is the requirement of motor starter?

Motor starters consist of two devices—a contactor that completes the circuit to the motor and an overload relay that monitors the current the motor is drawing. This overload protection device is set to a pre-determined maximum load that the motor can safely handle.

Which starter is used in induction motor?

The star delta starter is used for starting of induction motor above 5 H.P. Auto Transformer – The necessity of reduction of starting current to avoid failure of motor can be effectively done by auto transformer which consists of a single winding.
