FAQs
CM3537 uses a 56C frame with C-face mounting and offers both a foot-mounted base and horizontal mounting orientation. For installation, align the drive end flange with compatible couplings or belts, secure the feet to a rigid base, and ensure proper shaft alignment. Wiring should follow the 230/460 V dual-voltage configuration and use a Direct On Line start to minimize startup transient effects. Verify bearing lubrication intervals and seal integrity to maintain efficient operation.
The CM3537 is a 3-phase motor rated at 0.5 HP with dual voltage 230/460 V and a frequency of 60 Hz. It features a rated current of 1.6 A at nominal load and 0.8 A in light-load conditions, a service factor of 1.25, and a Direct On Line (DOL) starting method. These specs support straightforward integration, predictable inrush, and reliable performance in standard OEM equipment without external soft-starts for many light-to-medium duty tasks.
Yes. With its 0.5 HP rating, 3420 r/min speed, 56C frame, TEFC enclosure, and 3-phase design, the CM3537 is well-suited for small to mid-range conveyors, pumps, and fans. The 56C footprint and C-face/foot-mount mounting offer installation flexibility, while the TEFC enclosure protects internal components in dirty or humid environments, helping maintain uptime in continuous operation lines.
The CM3537 carries CSA/UR certification and adheres to NEMA standards, ensuring compliance for broad industrial use and safe integration into regulated environments. The motor’s TEFC enclosure supports rugged duty, and the 56C frame aligns with widely used industrial drives. These certifications help streamline procurement, reduce risk, and support regulatory alignment in North American facilities.
Maintenance benefits come from regreasable bearings and a robust TEFC enclosure, reducing lubrication-related downtime and protecting the windings from contaminants. The motor’s simplicity—DOL starting, 56C frame, and standard mounting—lowers installation and maintenance costs while enabling predictable thermal performance and longer bearing life, contributing to a favorable return on investment in mixed-velocity or continuous duty lines.
