Generator saves floor space

Generator saves floor space

Often, demonstrations on the floor of shows like National Manufacturing Week emphasize features that aren't necessarily critical in the real world. But one facet of Baldor Electric Co.'s OptiGen adjustable speed generator is important in both locations. It's much smaller than competitive products and it's quieter.

That's just as important at most of the sites where the generator will be used. Size benefits of the compact unit will vary, but it can trim size requirements by up to 50%.

While size is important in many fields, OptiGen's biggest advance is the use of electronics to adjust the system's motor to match the power requirements as they change. The motor in the OptiGen generator will speed up when power requirements rise, providing more power. In normal operation, that motor spins at 1,800 rpm. But when motors start or other temporary power demands arise, the motor can increase speed to up to 2,500 rpm, which also increases its output. Since most high power demands are relatively short, this technique is quite effective, Baldor spokesmen say.

Adjusting speed in this fashion saves energy and lets users employ smaller generators. It can also reduce acoustic noise by as much as 25%. There are also substantial energy savings over fixed systems, which often have to produce twice the power that's normally needed in order to meet peak requirements.
