Motor control fundamentals | Eaton PSEC

Electric motors are a critical part of our daily lives and as important is the ability to safely operate them. Motor starters provide that safety to both the operator and the motor itself. In this video Kyle Harrison, Product Manager Medium Voltage Control Assemblies, explains what motor starters are and how they work.

Motor starters are electrical devices used to safely start and stop motors while also providing them with overcurrent and undervoltage protection.

Along with a breaker or fuse, the primary components that go into motor starters are contactors and relays. The purpose of the contactor is to establish and interrupt the power circuit to the motor. Relays protect motors from drawing too much current and overheating.

Kyle also walks through the various motor starter designs and how they work including:
• Across-the-line (ATL) starter (also referred to as full voltage starters) – and how inrush current affects motors and the electrical system
• Reduced-voltage autotransformers
• Reduced-voltage primary reactors
• Solid-state soft starters (also referred to as reduced voltage soft starters (RVSS))
• Variable frequency drive (VFD)

We also explain how motor starter design is based on system voltage and discuss motor starters applications.
