Control Concepts provides repair and replacement services for EMS Industrial’s legacy low-voltage motor control components. Many of these products are still in use, and Control Concepts helps keep them operational with expert diagnostics and repair capabilities.
Who is EMS?
Founded in 1933 in Madison, Wisconsin, EMS Industrial, originally Electric Motor Service, built a reputation for quality electric motor repair and custom control systems. Over the years, they manufactured a range of low-voltage products used in industrial automation, HVAC, and mechanical systems.
What Do EMS Products Do?
EMS components were designed to regulate, start, and protect motors in industrial applications. These include:
- AC Motor Drives (VFDs) – Control motor speed and torque for energy efficiency and performance
- Motor Soft Starters – Limit inrush current and reduce wear during motor startup
- Electronic Motor Brakes – Enable smooth motor stops and enhance operator safety
- Heater Controllers – Manage temperature regulation for process systems
- Phase Controllers – Adjust AC phase angles to optimize motor function
- Protection Modules – Detect overloads, phase loss, and other electrical issues
- Control Panel Components – Relays, timers, contactors, and logic modules used in EMS-built panels
