FAQs
For a seamless retrofit ensure foot‑mounted alignment on a frame size 56, with a 0.63 in shaft and a TEFC enclosure. Use a 230 V supply for both armature and field windings, verify bearing lubrication intervals for the sealed 6205 bearings, and ensure mounting clearance to prevent heat buildup. This setup enables straightforward alignment with existing belts or couplings.
Key specs include 1 HP output, base speed of 1750 r/min, frame size 56, shaft diameter 0.63 in, 230 V armature and field voltage, TEFC enclosure, insulation class F, and a weight around 62 lb. It is designed for continuous operation and aligns with UL/CSA and NEMA standards for reliable industrial performance.
Yes. The motor uses a TEFC enclosure with a steel frame and sealed bearings, built to withstand dusty and moderately humid conditions. With an ambient rating up to 40 °C and rugged construction, it supports continuous duty in manufacturing and material handling environments while maintaining reliability and predictable maintenance intervals.
The D2304 carries UL/CSA electrical ratings and UR recognition, plus NEMA standards compliance. These certifications matter because they simplify integration into regulated facilities, ensure safety and interchangeability with compatible motor packs, and reduce qualification time for electrical panels and systems in industries such as automotive, packaging, and food processing.
The motor is stocked at multiple warehouses, with a listed lead time of 0 days, enabling rapid deployment. Warranty terms require return only for warranty issues, aligning with standard distributor practices. This availability supports aggressive maintenance calendars and quick turnarounds on critical spares for OEMs and end users alike.
