FAQs
The 7BCEM3158T uses a 143TC frame and supports both C‑Face and foot mounting configurations, enabling straightforward replacement in existing equipment footprints. Its horizontal mounting orientation simplifies alignment with conveyors, pumps, and general machinery, while the open/open‑frame to OPSB options provide installation flexibility in lean facilities where space and accessibility are critical.
OPSB enclosure combines protection against dust and moisture with ease of maintenance. The motor’s 60 Hz operation at 230/460 V, combined with a 40 °C ambient rating and 1000 m altitude capability, ensures reliable performance in challenging environments. The enclosure choice helps protect bearings and windings, reducing maintenance frequency and extending service life in harsh settings.
Yes. This motor is designed for 3‑phase power at 60 Hz, with dual voltage 230 V / 460 V capability and a 3‑pole, 2‑pole configuration. It provides 3 HP at 3450 rpm and Direct On Line starting, making it compatible with standard plant electrical infrastructure and easy to integrate with existing VFD controls or direct line feeds.
The motor carries NEMA‑related design features and IE2 premium efficiency. It is certified under CSA, CSA EEV, and UR, aligning with multiple U.S. and Canadian regulatory frameworks. The combination of these certifications supports compliance for industrial equipment, electrical safety, and energy efficiency in North American installations.
IE2 premium efficiency reduces energy draw across typical load profiles, lowering operating costs over the motor’s life. The regreasable bearings support longer intervals between service, while the robust 60 Min duty rating and durable 143TC frame minimize replacement frequency. Overall, the motor delivers lower total cost of ownership through energy savings, fewer maintenance cycles, and extended service life.
