Description

The AEUH 1HP 2-Pole Cast Iron Flange Mounted IE3 Premium Efficiency Motor features B5 flange vertical mounting. Rated speed 3460RPM with 82.0% efficiency at IE3 Premium Efficiency class, frame 80M, designed for small vertical circulation pumps, lab booster pumps and similar vertical equipment. The B5 flange face bolts directly onto the pump or driven equipment for a compact vertically-suspended integration, ideal for pump towers and vertical skids. IE3 saves roughly 3-5% energy versus IE1 standard-efficiency motors, typically recovering the efficiency premium within 1-2 years in vertical continuous-duty service. Cast iron housing and brackets deliver excellent structural rigidity, with stable axial load distribution during vertical operation and lower vibration and noise than comparable aluminum-frame vertical motors. The die-cast aluminum rotor integrates fan blades, bars, and end rings in a single casting for superior starting performance. The TEFC totally-enclosed design achieves IP54 protection for long-term stable operation in dusty and humid environments. Universal voltage 200V to 480V at 50/60Hz allows a single SKU to serve power grids worldwide. Fully certified to UL (North America), BSMI (Taiwan), and CE (Europe); IEC frame 80M flange dimensions meet international standards for direct interchangeability with market vertical equipment.
