The TEFC enclosure protects the windings from dust, moisture, and typical shop-floor contaminants, delivering higher MTBF and lower maintenance costs. In real-world pumping installations, this translates to fewer unscheduled stops and longer intervals between service, especially in dusty or humid environments. Applications include process pumps, water handling, and HVAC circulation where continuous operation is essential. The 0.50 HP output at 1725 rpm in a 3-phase design provides sufficient pump head while keeping energy usage proportional to load, reducing operating costs. This motor is well-suited for small-bore pumping, circulation, and lift tasks in manufacturing lines and packaging machinery. Dual voltage rating of 230 V / 460 V and 60 Hz compatibility simplifies retrofit projects and international installations, reducing wiring complexity and stock variety. It fits a 56YZ frame with foot-mounted, horizontal mounting, and standard Baldor-Reliance footprints to streamline installation and replacements.
