MAGNETEK INC., a supplier of digital power and motion control systems for material handling, introduced high-performance AC line regenerative systems, promising to save energy, time, and money. These industrial-grade units take surplus regenerative energy from the motor and return it to the AC power source, reducing total energy consumption and improving energy efficiency by 40-45%. They eliminate the need for dynamic braking resistors, and are an effective approach to high-duty cycle crane applications.
Magnetek supplies digital power and motion control systems used in overhead material handling, elevator, and mining applications. It is North America’s largest supplier of digital drive systems for industrial cranes, hoists, and monorails.
“AC Line regeneration products capture the regenerative energy which would normally be dissipated by resistors and puts that energy back on the grid. This regeneration reduces a company’s total energy usage and improves overall facility efficiency by eliminating energy waste. Heat that was previously produced by dumping excess power into resistor banks is also eliminated,” stated Aaron Kureck, Magnetek product & development director.
“By improving the operating efficiency of their overhead cranes with these systems, some users with high duty-cycle applications may recoup the cost of the regenerative drive in the first year,” he continued.
Two types are available to fit various applications. IMPULSE•R units are available with ratings from 5–100 HP, while the IMPULSE•D+ HHP modular, regenerative inverter platform is suitable for applications beyond 200 HP. They can be combined with the Magnetek’s IMPULSE•G+ or VG+ Series 4 adjustable frequency drives or retrofitted to the company’s IMPULSE•G+ or VG+ Series 3 drives and sized to fit the expected regenerative need.
