AC motor SP4T™

inductionthree-phase460 V

The idea is simple. Take the best and proven AC induction design and make it better by reducing motor losses by an average of 20% while maintaining the simplicity of today's installed base of AC induction motors. ABB Baldor-Reliance Super-E® NEMA Premium Efficient (IE3) ABB Baldor-Reliance SP4 NEMA Premium 4 Efficient (IE4) AC induction motor • Slip losses in rotor (I2R) • Heats bearings and motor • Lower efficiency adds to heat generated AC induction motor • Longer stack (both stator and rotor) – less loss • Runs cooler – less loss in bearing and motor • Higher efficiency GENERAL PURPOSE Three phase, totally enclosed, 230/460V Features • 60 Hz designs • 2,4,6 pole • 1-20 Hp ratings • Suitable for inverter use per NEMA MG1 Part 31.4.4.2 * • Cooler operation for longer lifespan Applications • Fans • Pumps • Blowers • Conveyors • Compressors • Industrial machines • Other general purpose applications
