EMB Controls Division Motor Control Panels, Low Voltage Switchgear and Consoles.

EMB have been producing AC and DC motor control panels and distribution switchgear panels since 1948 and our ability, success and reputation in this area has become widely recognized. Consequently, our control equipment, often incorporating programmable logic control (PLC) systems, is operating in major industries such as nuclear, power generation, steel, coal, automotive and water supply.

EMB sell more than just the control engineering hardware for these applications. With every control system we can supply the essential comprehensive engineering expertise which enables our customers to gain the maximum benfit and efficiency from installed systems:

  • Site surveys and assessments.
  • Preparation of electrical control specifications.
  • Detailed design packages, incorporating layouts, schematic diagrams, connection diagrams etc.
  • PLC software design.
  • Manufacture of control panels and switchgear to clients' specifications.
  • Maintenance contracts.


Manufacture and supply of new eddy current speed control systems also continues, using proprietary contactor and relay equipment, and our own Microsen Eddy Current unit and closed loop speed control system. The closed loop system does not require the use of a Tacho-generator feedback but this can be incorporated to meet special requirements.
