FAQs
The motor supports horizontal mounting with a foot-mount configuration and a C-face flange option, facilitating straightforward retrofits or OEM integration. This combination allows quick alignment with conveyors, pumps, or fans while maintaining proper shaft alignment and vibration control. For installation, ensure compatible drive-end mounting and enclosure openness align with your equipment.
This model is a dual-voltage 230/460 V, 3-phase motor designed for 60 Hz operation. It can be wired for either supply while preserving the same frame and mounting footprint. When configuring, use appropriate starter protection and ensure wiring matches the voltage rating to maintain optimal torque and temperature performance.
Yes. With 0.5 HP output, 1725 rpm, and a robust 56C frame, the motor provides reliable, steady performance for lightweight to mid-duty drives. The Direct On Line starting and open enclosure are advantageous for simple control schemes and easy service in typical factory floors where ventilation is available and ambient temps are within 40 °C.
The product references NEMA standards and UL/cURus energy listings, which support compliance with typical North American electrical and safety requirements. These certifications help simplify procurement for regulated facilities and OEMs by aligning with established reliability and safety benchmarks during audits and maintenance planning.
Plan for standard maintenance of a ball-bearing induction motor with a 60-minute duty rating, open enclosure, and class B insulation. Routine checks should cover bearing noise, temperature rise, and winding integrity. The warranty policy indicates returns for warranty-covered issues, so document performance deviations promptly and coordinate with stocking warehouses to minimize downtime.
