FAQs
Yes. The EM3546T-57 supports 230/400 V, 50 Hz three-phase operation and uses the standard 143T frame with a foot-mounted, horizontal orientation. It is designed for direct-on-line starting and TEFC protection, making it a straightforward drop-in replacement for many legacy 143T motors in factory basements and equipment housings.
Key specs include 1 HP output, 1440 r/min (4 poles) at 50 Hz, 230/400 V, 3-phase, and IE3 efficiency. The motor operates in continuous duty with a 74% power factor, insulation class F, and a 0.88 in shaft diameter. It’s a robust general-purpose motor suitable for long-running industrial tasks.
It's well-suited for conveyors, pumps, and general machine tool drives where reliable, continuous operation and easy integration with existing 143T bases are valued. Its TEFC enclosure protects internal windings in dusty or humid environments, making it a versatile upgrade for modernization projects or new production lines.
The motor carries IE3 efficiency along with CE, CSA, UR, and WEEE compliance, supporting global regulatory requirements. This combination helps meet energy-saving targets and simplifies procurement for multinational facilities seeking standardized motors across sites.
Direct-on-line starting reduces ancillary start-up components and maintenance complexity, while the TEFC enclosure and steel frame promote durability with lower downtime. Stocked availability (zero lead time in some listings) supports fast replacements, contributing to favorable ROI through reduced maintenance intervals and extended service intervals.
