Motor Controls in San Diego

ESU Buys and Sells New, Used, Surplus and Obsolete Motor Controls in San Diego, Orange County, Riverside and Nationwide

Electrical Supplies Unlimited (ESU) buys and sells motor controls for commercial, industrial and electrical applications. We help electrical contractors, maintenance departments, manufacturers and businesses locate motor control equipment for new installations, equipment repairs and replacement projects. Our sourcing capabilities include new, used, surplus, obsolete and hard-to-find electrical components.

Motor control equipment is used to operate, regulate and protect electric motors in a wide range of applications. These systems are commonly found in manufacturing facilities, commercial buildings, HVAC systems, pumps, conveyors, compressors and industrial machinery. Whether you need a motor starter, contactor or another motor control component, ESU can help you explore available sourcing options.

What Are Motor Controls?

Motor controls are electrical devices and systems used to start, stop, regulate and protect electric motors. Depending on the application, a motor control system may include contactors, overload relays, motor starters, control relays, pushbuttons and variable frequency drives. These components work together to manage motor operation and provide the appropriate control and protection for connected equipment.

Motor control requirements vary depending on motor horsepower, voltage, phase, operating conditions and the type of machinery being controlled. Industrial applications may require more complex control arrangements than smaller commercial installations. Selecting compatible components is important when replacing equipment or maintaining an existing motor control system.

Motor Controls vs. Motor Starters

Motor controls and motor starters are closely related, but the terms do not mean exactly the same thing. A motor starter is a device designed primarily to start and stop an electric motor, commonly using a contactor and an overload protection device. Motor controls describe the broader category of equipment used to manage motor operation.

Depending on the application, motor control systems may provide additional functions such as speed regulation, operating sequences, remote control and equipment interlocking. A variable frequency drive, for example, can regulate the speed of a compatible AC motor by controlling the frequency and voltage supplied to it.

ESU also buys and sells motor starters for customers looking for individual starting components or replacement equipment.

Motor Control Components and Electrical Equipment

Motor control systems can incorporate several different electrical components, each serving a specific purpose. Common components include:

  • Motor starters: Used to start and stop electric motors and, in many configurations, provide overload protection.
  • Contactors: Electrically operated switching devices used to control power supplied to motors and other electrical loads.
  • Overload relays: Devices designed to protect motors against sustained overcurrent conditions associated with overloading.
  • Control relays: Used in control circuits to operate equipment and manage electrical sequences.
  • Variable frequency drives: Used in compatible applications to regulate AC motor speed and operation.
  • Motor control panels: Assemblies that house control devices and associated electrical components for operating machinery and equipment.

Equipment requirements depend on the motor and its intended application. When sourcing a replacement, it is important to identify the original component and verify its electrical ratings and compatibility with the existing system.

New, Used, Surplus and Obsolete Motor Controls

Electrical Supplies Unlimited provides sourcing options for new, used, surplus and obsolete motor control equipment. This can be especially useful for businesses maintaining older machinery or industrial systems that require specific components no longer readily available through conventional distribution channels.

When a motor control component fails or becomes obsolete, replacing the entire control system may not always be necessary. Depending on the equipment design and application, locating the correct replacement component may provide another option. ESU can help customers search for hard-to-find motor controls using manufacturer information, catalog numbers and equipment specifications.

We also purchase surplus electrical equipment from contractors, businesses, manufacturers and industrial facilities. If your company has unused or excess motor controls, starters, contactors or other electrical components, contact ESU to discuss selling your inventory.
