Starter

Definition

A starter is a device that ensures that a motor does not receive excessive current during start-up.

Purpose

The purpose of a starter is to protect electric motors from damage caused by high inrush currents during start-up, ensuring smooth and safe operation.

Examples of Use

• Industrial machinery uses starters to control the start-up current and protect motors from electrical surges.
• HVAC systems employ starters to manage the initial power load when compressors and fans start.
• Automotive engines use starters to engage the motor smoothly and prevent damage from sudden power application.

Related Terms

• Motor Control: Devices and methods used to manage the operation of electric motors.
• Overload Protection: Mechanisms that protect electrical equipment from damage due to excessive current.
• Inrush Current: The initial surge of current required to start an electric motor.

Notes

Starters are critical for extending the lifespan of electric motors and ensuring safe and efficient operation, particularly in industrial and heavy-duty applications.
