RPM AC Inverter and Vector Duty motors

Product Announcement from Baldor Electric Company

RPM AC Inverter and Vector Duty motors have been developed specifically for use in variable speed PWM controller applications where fast response to speed commands and high speed torque are required. They virtually eliminate motor damaging reflective wave problems that plague many motors marketed as variable speed. RPM AC motors are up to three frame sizes smaller, resulting in drastically reduced rotor inertia, and weigh less than NEMA frame motors making them idea for use where size and space are important issues. For wide constant torque and constant horsepower ranges, including continuous operation at stall, RPM AC is the ideal motor solution.
