Why this motor stands out
- 56C frame compatibility: A widely used footprint that makes replacements and upgrades straightforward within many existing tool machines, conveyors, pumps, and grinders. The standardized mounting and bolt pattern mean less downtime when swapping in a compatible unit.
- Keyed shaft: Ensures secure, repeatable coupling to belts, pulleys, or couplings, reducing the risk of slippage under load and simplifying alignment during installation.
- Solid current draw and voltage: Operates at 230V with a predictable 14.4A draw, helping you plan electrical requirements and panel protection without surprises on startup and steady-state operation.
- Service Factor 1.15: Provides a practical margin for peak torque during brief overloads, start-up transients, or slightly tougher workloads — helping extend motor life under real-world conditions.
Ideal applications
- Small-to-mid sized machinery that requires a reliable 3 HP drive, such as machine tools, saws, presses, and grinders.
- Conveyor systems and material-handling setups that benefit from a stable 3450 RPM output.
- Pumps, fans, or blowers in workshop or light industrial environments where 230V operation is standard.
Practical installation tips
- Verify your equipment’s mounting alignment with the 56C frame’s standard bolt pattern to minimize vibration and wear.
- Confirm electrical supply compatibility with a 230V source and ensure appropriate overload protection and wiring gauge for 14.4A continuous draw.
- Pair the keyed shaft with a matched pulley or coupling, then perform a careful alignment check after initial operation to maximize efficiency and service life.
