• Totally enclosed design as standard (air or liquid cooled) • Variable speed enabled • Easy frequency and voltage selection • Substantial weight and size reduction • High efficiency throughout speed range • Low noise level generator signature • Improved power quality with low THD (<3%) even under non-linear loads (<4%) • Voltage transient load capability within ANSI C84.1 B • No frequency deviation • Capable of operating with 80–100% unbalanced loads • Decrease in fuel consumption • Increase in engine life and reduction in service requirements • No need to oversize engine and generator due to motor starting requirements (up to 400% overload capability for 1 second) • Low life-cycle cost
Cost effective variable-speed power generation has been a goal of industry for many years. Engines have optimal running conditions, where fuel consumption and engine wear is minimized. These conditions vary from engine to engine and most often are different than a wound-field generator’s synchronous speed. Recently, this important subject has been receiving greater attention worldwide, as the industry recognizes the need for greater fuel savings, a smaller and lighter overall system, and lower maintenance costs. The variable-speed benefits have traditionally been offset by high initial investment. With the introduction of low cost and high efficiency permanent magnet generators, coupled with advanced power electronics, the equation is now swinging in favor of variable-speed. The MAGNASMART™ generators use the most advanced technology and effectively solve this problem. They have a totally enclosed design, and of course, variable speed capability.
