Enclosed Motor Starters
What is an enclosed motor starter? Enclosed motor starters are electromechanical switches, comparable to relays. The primary difference between a relay and a starter is that a starter provides overload protection for the motor. With electrically-operated enclosed motor starters, contactors are used for switching the power-carrying conductors. When the coil in the contactor is energised, it produces the electromagnetic field and that pulls the switch contacts. When the coil is de-energised, contacts are pulled back to the normal position by a spring arrangement. How to improve motor starter efficiency? Designing a more energy-efficient motor starter creates cost savings over the lifetime of the equipment. Industrial infrastructures consume more than 31% of the available energy in the world and electrical motors alone represent more than 60% of that energy consumption. The purchase price of a motor also only accounts for 2 to 3% of the overall costs, the remainder of the expense primarily being energy consumption.
