After more than a year of field testing, a new magnet controller manufactured by Hubbell Industrial Controls has demonstrated that it will vastly reduce maintenance demands while enabling maximum efficiency and control during operation, even in high duty-cycle lifting applications.

Hubbell announced the new controller as ready for market in co-operation with its originators, Control Services of Westmont, IL. Hubbell will manufacture the patent pending e-mag controller. Winkle Industries, Hubbell’s master distributor, will market the e-mag controller for use on all makes and models of mobile cranes in recycling and steel mill material handling applications.

Control Services’ John Samila explains that the e-mag DC generator controller takes a dramatically new approach to controlling all power fluctuations inherent in the duty cycles and demands of lifting magnet applications.

“The current generation of solid state DC magnet controllers are static controlled devices that are subject to speed and load variations that may negatively impact the magnet system efficiency,” he says. These systems are generally outmatched by the job, absorbing massive voltage spikes through very sudden surges and drop-offs. “Our e-mag controller withstands and eliminates inherent magnet system problems by controlling the source which is the generator.”

Instead of reacting to magnet system failures as other units do, the e-mag controls the flow coming out of the generator before it becomes an issue. In essence, the e-mag prevents failures by protecting the magnet system and controlling the generator output for optimum efficiency.

The e-mag design is ideal for high demand operations and is available for generators from 5 kW to as much 50 kW, with no fear of problems with maximum voltages.
