Carrier HD52DL857 Motor

The Carrier HD52DL857 Motor is a high-performance 1 HP blower motor designed for heavy-duty HVACR applications requiring a 3450 RPM synchronous speed. This three-phase motor operates on a dual-voltage 230/460V configuration, providing the torque necessary for industrial-grade air handlers and large-scale ventilation systems. Built with a robust L56 frame, it features a 5/8-inch diameter shaft that extends 2 inches, ensuring a secure fit for standard drive assemblies. As a veteran-grade OEM replacement motor, it offers reversible rotation (CW/CCW), allowing field technicians to adapt the unit to specific blower wheel orientations without carrying multiple SKUs.

Engineered for continuous duty, the HD52DL857 eliminates the need for external capacitors by utilizing balanced 3-phase power, which reduces potential failure points in the electrical circuit. Whether you are replacing a worn-out A.O. Smith 7-152784-20 or upgrading a Carrier/Bryant/Payne furnace blower, this motor provides the reliability required for high-static pressure environments. The industrial-grade construction ensures efficient heat dissipation and thermal stability during peak operating cycles.

• High-Speed Performance: Delivers 3450 RPM at 1 HP for maximum airflow in demanding HVAC systems.
• Dual-Voltage Versatility: Supports both 230V and 460V 3-phase power supplies for broad site compatibility.
• Field-Adaptable: Features reversible rotation to accommodate various blower and fan configurations.
• Standardized Mounting: The L56 NEMA frame and 5/8" shaft ensure straightforward installation in most OEM bracketry.
• Reduced Maintenance: Three-phase design provides higher starting torque and eliminates start/run capacitor replacements.

• What are the shaft dimensions for the HD52DL857? This motor features a 5/8" diameter shaft with a 2-inch length, suitable for standard pulleys and direct-drive blower wheels.
• Can this motor replace a single-phase unit? No, this is a 3-phase motor and requires a three-phase power supply; it cannot be wired for standard 120V or 230V single-phase residential circuits.
• Is this motor reversible? Yes, the rotation is electrically reversible, making it a versatile drop-in replacement for motors with different factory rotations.
