P28631036 Continuous-Duty Three-Phase Induction Motor

The P28631036 is a heavy-duty continuous‑duty AC induction motor manufactured by Reliance Electric, built to NEMA standards for long‑term, high‑load operation in demanding industrial environments. It delivers consistent power, rugged reliability, and stable performance for critical applications requiring non‑stop operation.

This motor has a rated power of 10 HP, a nominal full‑load speed of 1180 RPM, and a 6‑pole design, optimized for low‑speed, high‑torque output. It operates on 460 V three‑phase voltage at 60 Hz, compatible with standard North American industrial power systems and suitable for integration into both new and existing drive setups.

Constructed with a 284U NEMA frame and a totally enclosed fan‑cooled (TEFC) enclosure, the P28631036 provides superior protection against dust, moisture, debris, and corrosive contaminants. The heavy‑duty cast‑iron frame ensures exceptional structural rigidity, minimizing vibration and noise during continuous operation, while the external cooling fan and optimized internal airflow maintain efficient heat dissipation even under full‑load or cyclic‑load conditions.

Designed for continuous‑duty operation, the motor features a high‑quality squirrel‑cage rotor and a balanced rotor assembly to deliver smooth performance and consistent torque. It is equipped with a Class F insulation system that offers excellent thermal resistance, allowing for higher operating temperatures and improved reliability under heavy or prolonged loads. High‑precision sealed ball bearings at both ends reduce friction, lower maintenance requirements, and extend service life.

The P28631036 is designed for foot‑mounted installation with standard mounting dimensions for easy alignment and secure fastening. The output shaft is machined with a keyway for reliable connection to pulleys, gears, couplings, and other transmission components. It works seamlessly with across‑the‑line starters, contactors, and variable frequency drives (VFDs), supporting precise speed and torque control for industrial automation and process equipment.

Typical applications include large conveyors, crushers, mixers, extruders, industrial fans, blowers, pumps, and other heavy‑duty machinery requiring high torque, continuous operation, and long‑term durability. As a robust original equipment manufacturer (OEM) component and a direct replacement for aging motors, the P28631036 combines proven performance, rugged design, and cost‑effectiveness for industrial users worldwide.
