Description

The AEUH 1HP 4-Pole Cast Iron Flange Mounted IE3 Premium Efficiency Motor features B5 flange vertical mounting. Rated speed 1730RPM with 85.5% efficiency at IE3 Premium Efficiency class, frame 80M, designed for vertical mixers, chemical dosing pumps and similar vertical equipment. VFD-compatible design with low THD allows precise flow control of vertical pumps via variable-frequency drives. Pre-lubricated double-sealed bearings eliminate routine greasing, ideal for elevated, hard-to-reach vertical mounting points. 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.
