Feature → Business Impact → Application: Three-phase motor with a 28M frame delivers high torque and consistent speed for demanding material removal, reducing cycle times in grinding and buffing operations. In practice this translates to improved throughput on metalworking machines while maintaining operator safety and quality finish. Application: primary use in workshop grinders and lathes where 1.5 Hp at 575 V powers heavy-duty grinding tasks. Feature → Business Impact → Application: TENV enclosure and steel frame protect internal components from dust and heat, extending motor life in shop floors with washdown risk or high humidity. Application: ideal for continuous-duty grinding bays, trimming, and deburring lines. Feature → Business Impact → Application: Direct-on-line starting simplifies electrical installation and reduces control hardware, lowering initial capital and startup time. Applications include line starts on CNC benches and manual grinding stations. Feature → Business Impact → Application: Foot-mounted, horizontal orientation simplifies mounting to existing bases and aligns with common workshop configurations, enabling quick retrofits. Applications include retrofit projects in automotive, aerospace, and general metal fabrication. Feature → Business Impact → Application: UL/CSA certifications and US-origin components reinforce compliance, enabling easier audits and supplier qualification. Applications include regulated manufacturing environments and procurement programs prioritizing safety and traceability. Feature → Business Impact → Application: Stocked at multiple warehouses with 0-day lead time reduces downtime and spares risk in critical maintenance windows. Applications include just-in-time production lines and long-term maintenance contracts in US and global plants.
