FAQs
The 7BCEM31155 uses a 56C frame with C-Face mounting and foot-mounted orientation. It supports direct-on-line starting and 3-phase connections at 230/460 V, 60 Hz. When retrofitting, ensure bolt patterns align with standard 56C footprints, verify shaft diameter of 0.63 in, and confirm clearance for OPEN enclosure cooling and service access.
Key specs include 2 HP output, 3450 r/min nominal speed at 60 Hz, voltage 230/460 V, and a power factor of about 0.85. Equipped with IE3 Premium efficiency and insulation class F, the motor delivers lower running losses, reduced heat generation, and improved overall energy efficiency over a typical NEC motor, enhancing long-term operational cost savings.
Yes. The 7BCEM31155 is designed for continuous duty with an OPEN enclosure, 56C frame, and 3-phase operation. Its NEMA Design B, insulation class F, and IE3 Premium efficiency support reliable operation under steady loads, while the open design allows effective cooling in standard industrial environments.
The motor aligns with NEMA design standards (B), features IE3 Premium efficiency, and is specified for use in US-sourced assemblies. Its data also references a UL/CSA-style regulatory path via certification agency notes, ensuring suitability for industrial installations in North America and compatible with common compliance expectations.
Warranty terms typically require proper handling of warrantyed components, with returns for faulty units. Stocked availability (0 day lead time) minimizes downtime and accelerates service. ROI benefits come from IE3 efficiency, reduced energy consumption, and lower maintenance costs due to robust design, long-life bearings, and standard frame compatibility for easy replacement in existing lines.
