Feature → Business Impact → Application: The 0.5 HP, two-pole, 3-phase design delivers dependable torque for small machinery, reducing start-up stress on belts and gears and enabling smoother piece-rate cycles in grinders and lathes. This directly translates to higher uptime and predictable throughput in metalworking operations that demand steady RPM control at 50/60 Hz. The grounded enclosure (GRND) enhances safety and simplifies compliance during maintenance, while the foot-mounted horizontal mounting supports straightforward retrofits into existing bases without custom adapters. In practice, this means faster installation, less downtime, and clearer maintenance planning for shop floors running small grinding, buffing, or belt-sanding stations. The motor’s rated current profile (0.85 A / 0.8 A / 0.4 A) supports careful electrical planning and reduced energy waste when running at the lowest practical load. The 208/230/460 V options and direct-on-line starting remove the complexity of soft-start circuits, lowering total cost of ownership and enabling fast, reliable startup at the device level. With an ambient rating of 40 °C and steel frame construction, the motor withstands common industrial environments, improving overall equipment reliability and maintenance intervals. The product is stocked at multiple US and international warehouses with zero-day lead times, ensuring rapid procurement and component reuse across multiple lines, which is especially valuable for OEMs and maintenance teams chasing lean inventory goals. Long-tail keywords addressed include 3-phase motor 0.5 HP, foot-mounted motor, GRND enclosure, 50/60 Hz motor, and direct-on-line starting for compact automation setups.

FAQs
The 7B7309 is a foot-mounted motor with horizontal mounting, designed for standard drive ends. Shaft diameter is 0.63 inches, which works with common couplings and pulleys used in grinders and belt sanders. When planning a retrofit, verify your base pattern and ensure the drive end flange is compatible with your current equipment to minimize downtime.
Yes. The motor is rated for continuous duty and is specified as 3-phase, 2-pole operation with direct-on-line starting. With a GRND enclosure and 40 °C ambient capability, it supports sustained operation in typical workshop environments while maintaining stable torque and RPM control for grinders, buffers, and other small industrial machines.
The motor supports 208 V, 230 V, and 460 V, enabling compatibility with common North American electrical systems. This reduces the need for rewiring or voltage converters during installation, allowing quick integration into existing control panels and improving first-run startup times.
The 7B7309 carries CSA certification for North American markets and is manufactured in the United States, providing clear traceability and compliance. It is also classified under ETIM 7 EC001851 for electric motors, aiding cataloging and interoperability across industrial procurement platforms.
Lead time is effectively 0 days, and the product is stocked at multiple warehouses (including US and international facilities). This enables rapid fulfillment, reduced safety stock, and quicker repairs or replacements for grinding, buffing, and other light-duty 3-phase machines.
