AC Laminated Frame - RPM AC Motors

Baldor-Reliance industrial electric motors are available for most general purpose applications and processes. However, some AC Variable Speed applications require high performance capabilities including constant torque down to zero speed, wide constant horsepower range, high response applications that require low inertia rotors, or high speed capabilities. The RPM AC motor is most suitable for tough variable speed industrial applications where high performance, and power density (compact size and weight) is most important. RPM AC laminated frame motors are available in both standard induction and ultra high-density Interior Permanent Magnet (IPM) versions.
