Quarry Duty Motor – Design C, 2–10 hp, High Torque, TEFC, IP55 | Baldor•Reliance

The Baldor•Reliance Quarry Duty Motor – Design C is purpose-built for tough applications such as conveyors, crushers, and gear reducers commonly found in mining, aggregate, and quarry sites. Featuring a high starting torque NEMA Design C electrical profile, this motor ensures the required force to start heavy-duty loads and maintain reliable torque throughout operation.

With a horsepower range from 2 to 10 hp and NEMA frame sizes 145T through 215T, this motor is suited for a wide variety of industrial setups. It offers Totally Enclosed Fan Cooled (TEFC) construction with a steel band frame and robust cast iron endplates, fan cover, and conduit box to endure vibration, dust, and moisture.

The IP55 enclosure rating safeguards the motor internals from water and dust ingress, while the gasketed conduit box and shaft seal enhance environmental protection. Class F insulation with a Class B temperature rise provides superior thermal performance, and the 1.15 service factor allows the motor to handle temporary overloads with ease.

Engineered for compatibility with variable frequency drives, this motor is inverter-ready, delivering flexible speed and torque control without compromising performance.
