Why this motor stands out
- Compact yet capable: A 56J frame packs reliable power into a small footprint, ideal for tight machine enclosures and retrofit projects.
- Threaded shaft for simple coupling: Eliminates the need for additional adapters, reducing setup time and potential alignment issues.
- Dual voltage flexibility: Configured for different wiring schemes without needing a separate motor, simplifying inventory and maintenance.
- Solid torque with a generous service factor: A 1.65 SF supports demanding loads and startup surges common in conveyors, fans, pumps, and machine tools.
Ideal applications
- Conveyor systems and material handling equipment requiring reliable, single-speed drive
- Machine tools, grinders, or saws that need a durable C-face motor for direct mounting
- Industrial fans and blowers where a compact 1 HP drive is sufficient
- Replacement for legacy equipment with 56J C-face, threaded-shaft motors
Practical installation tips
- Match the winding configuration and supply voltage to achieve the desired speed (3450 RPM for typical two-pole, 1725 RPM for four-pole arrangements at standard frequency).
- Use a compatible coupling or belt pulley with the threaded shaft to ensure secure torque transfer and easy alignment checks during setup.
- Confirm mounting alignment and vibration isolation to maximize bearing life and reduce wear on connected components.
- Inspect electrical connections for secure, clean wiring at the dual-voltage terminals to prevent heat buildup during operation.
This C-Face Motor With Threaded Shaft delivers a practical blend of mounting convenience, reliable performance, and flexible wiring—making it an excellent choice for engineers, maintenance technicians, and OEMs updating or retrofitting equipment that demands steady, predictable drive performance.
