P56H5068U Reliance Electric General-Purpose Three-Phase Induction Motor

The P56H5068U is a compact general-purpose three-phase induction motor manufactured by Reliance Electric, conforming to NEMA 56C frame specifications. It is engineered for continuous light to medium duty operation, featuring stable performance, compact structure and easy installation for various commercial and light industrial scenarios.

This motor is designed with a 2-pole winding configuration, delivering a nominal full-load speed of around 3450 RPM at 60 Hz. It is rated for three-phase 208-230/460 V power supply, which matches most standard industrial and commercial power distribution systems. Adopting Class B insulation, it can withstand a maximum operating temperature of 130°C, providing reliable thermal protection for internal windings during long hours of continuous running. The motor is configured with a standard service factor of 1.0, intended for steady operation under rated load conditions.

It adopts a sturdy cast iron NEMA 56C frame that guarantees structural stability while keeping the overall size compact, so it can be flexibly installed in equipment with limited space. Equipped with a Totally Enclosed Fan-Cooled enclosure, the motor effectively isolates internal components from dust, dirt and ambient moisture, adapting well to indoor workshops, commercial facilities and regular production environments. The external cooling fan works with optimized internal airflow paths to dissipate heat efficiently and avoid overheating during prolonged operation.

High-quality sealed ball bearings are mounted at both ends of the rotor shaft. These bearings reduce mechanical friction, operate smoothly with low noise, and require almost no regular lubrication maintenance, greatly extending the service life of the motor. The precision-machined output shaft is fitted with a standard keyway, enabling firm connection with pulleys, gears and light-duty couplings for stable power transmission. As a foot-mounted motor with standard NEMA mounting dimensions, it can be quickly positioned and securely fixed on equipment bases and brackets.

The built-in squirrel-cage rotor is professionally dynamically balanced to ensure low vibration and quiet running throughout the working cycle. Made of high-quality copper windings and produced under strict factory quality control, the motor maintains high operational efficiency and a low failure rate under normal working loads. It is fully compatible with conventional line starters, contactors and basic variable frequency drives, supporting simple speed regulation and seamless integration into light industrial control systems.

The P56H5068U is widely applied to a wide range of light industrial and commercial equipment, such as small high-speed fans, blowers, water pumps, light-duty conveying devices, packaging machines and general workshop machinery. It is an ideal choice for original equipment assembly and also serves as a perfect direct replacement for outdated motors in existing equipment. With reliable quality, small footprint and outstanding cost performance, it remains a popular power solution for light-duty drive applications.
