Description
Meet the NIDEC US Motor C-Face Threaded Shaft Two-Speed 230V 56J Frame — a compact, durable drive engineered for reliability in a wide range of small machinery. Built with a C-face mounting footprint and a threaded shaft, this motor delivers straightforward installation and robust performance in both high- and low-speed applications.
Key strengths that set it apart
- C-face mounting provides versatile, flush alignment with your equipment, making retrofits and new builds simpler and more reliable.
- Threaded shaft enables secure, easy coupling or pulley attachment without additional adapters, reducing setup time and misalignment risk.
- Two-speed capability delivers 3450 RPM at high speed and 1725 RPM at low speed, offering flexible control for processes that require different belt tensions, torque profiles, or speed settings.
- 230V operation with clearly specified amperage: approximately 10A on high speed and 2.2A on low speed, helping you design efficient electrical feeds and protect circuits.
- 56J frame ensures broad compatibility with existing mounts and accessories, easing installation in established systems.
- Service Factor 1.65 provides a comfortable margin for startup surges and transient loads, extending drivetrain life in demanding environments.
- Trusted brand lineage from NIDEC / US Motor, known for rugged, dependable motors that stand up to continuous-duty use in automation, packaging, conveyors, and small machinery.
What this motor is ideal for
Designed for equipment that benefits from occasional speed changes without swapping gearboxes, belts, or drives. Examples include:
- Conveyor systems where products require different transport speeds during loading or transfer phases.
- Mixing, mixing-and-dispensing, or feeder applications that adapt to different cycle times.
- Small pump or fan assemblies that require a high-speed startup and a lower-speed running option for efficiency or noise reduction.
- Machining or packaging lines where a single motor can drive multiple processes with simple speed selection.
How it compares to other solutions
Rather than adding a separate gearbox or a complex drive system, this two-speed C-face motor provides speed versatility in a compact footprint. The threaded shaft and C-face mounting minimize installation complexity, while the 56J frame keeps compatibility with a wide range of mounting plates and accessories. The result is a streamlined upgrade path for legacy machines or a clean integration point for new equipment where space and ease of installation matter as much as performance.
Practical use tips
- Pair the motor with matched pulleys or couplings sized for the two speeds to maintain optimal torque and belt life.
- Ensure proper electrical provisions for 230V operation and size protective devices to accommodate the high-speed current draw (about 10A) and the low-speed draw (about 2.2A).
- Align components carefully to preserve the threaded shaft’s integrity and reduce premature wear on bearings and seals.
- Use the SF 1.65 rating as guidance for startup surges; design power transmission and drive selections with a safety margin to handle peak loads.
- Consider thermal effects during two-speed operation; provide adequate cooling or ventilation in enclosed or high-load environments.
