FAQs
Yes, the 7B7306 supports 115 V or 230 V operation and is suitable for direct-on-line starting in 1-phase, 60 Hz systems. Its foot-mounted, GRND enclosure design aligns with common Baldor/ABB frames, enabling straightforward replacement in grinders, buffers, and small lathes without major cabinet changes.
The motor delivers 0.5 HP at 1800 RPM (4-pole, 1-phase, 60 Hz). This combination provides consistent torque for light-duty machine tools, with predictable acceleration and reduced thermal stress compared with lower-rpm varieties. The 115/230V dual voltage supports flexible wiring, minimizing the need for dedicated transformers on the shop floor.
Absolutely. The 0.5 HP, 1800 RPM, single-phase configuration with GRND enclosure is ideal for grinders, buffers, lathes, and belt sanders. Its sturdy steel frame, 0.63 in shaft, and horizontal foot-mounting simplify mounting on workstations and retrofit projects, while maintaining alignment with standard drive couplings.
This motor is UR certified and manufactured in the United States, supporting regulatory compliance and qualification for safety audits. The GRND enclosure and insulation class B further reinforce suitability for industrial environments and routine maintenance checks.
Stocked at multiple warehouses with 0-day lead time in supplier records reduces downtime risk. Warranty terms indicate standard returns for warranty-covered units, ensuring business continuity and favorable total cost of ownership for OEMs and service providers.
