NEMA Motor Overview - Rocky Mountain Baldor
www.rockymountainbaldor.comABB drives and motors help solve the energy challenge More than 90 percent of industrial motors either cannot adjust their power consumption or use very crude methods to do so. Many always run at full speed, regardless of the actual output needed. In many applications, energy use can be cut to one-eighth just by reducing the motor speed by half.
