FAQs
The motor uses C-Face mounting with a foot-mounted base and horizontal orientation (F1). This supports straightforward alignment on 145TC frames, simplifies bolting to a rigid base, and reduces rework during installation. Ensure proper shaft alignment and torque per the catalog sheet, and use compatible adapters if integrating with existing equipment.
The 7BCEM3158T-G is a 3-phase motor rated for 230 V or 460 V, operating at 60 Hz. It provides a nominal speed of 3450 r/min (with a synchronous speed of 3600 r/min) and a rated current of 7.6 A or 3.8 A depending on voltage. This makes it suitable for standard industrial power distribution without special transformers.
Yes, it is designed for Continuous duty and comes with an OPSB enclosure, providing robust protection in challenging environments. The insulation class is H, supporting prolonged operation at elevated temperatures, and the enclosure helps resist dust, moisture, and general contamination common in process and packaging lines.
