Your question: Do you need a motor starter?

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.

When should a motor starter be used?

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 is the point of a motor starter?

A motor starter provides defense by first controlling the electrical output of your device or equipment at its initial point of operation (when you turn it on or it engages). From that point, the starter continues to protect your system, operating as a fail-safe.

Does a 1/3 hp motor need a starter?

Motors below 1 HP (0.7457) is directly connected to the power supply without starter because their armature resistance is very high and they have the ability to afford and pass higher current due to high resistance. So the armature windings are safe from the high starting current while staring a motor.
