NEMA Motor Overview - Rocky Mountain Baldor
ABB 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.

THE MYSTERY OF MOTOR FRAME SIZE - Rocky Mountain …
www.rockymountainbaldor.comTHE MYSTERY OF MOTOR FRAME SIZE INTRODUCTION Industrial electric motors have been available for nearly a century. In that time there have been a great many changes. One of the most obvious has been the ability to pack more horsepower in a smaller physical size. Another important achievement has been the standardization of motors by the National
