Information About 3M576D

The 3M576D is part of Dayton’s line of HVAC/R motors engineered for small fan and blower systems requiring consistent airflow and continuous-duty operation. It runs on 115 VAC at 60 Hz with a 1/10 HP output and uses a shaded-pole motor design with sleeve bearings for quiet, low-maintenance service. The motor features CWSE rotation, an open enclosure, and a built-in automatic thermal protector to ensure safety during extended use. With a 3/8-inch shaft diameter, ring/stud mounting, and compatibility across multiple voltage classes, it integrates easily into HVAC equipment and replacement applications.

Key Features:

• 1/10 HP Shaded-Pole Motor: Provides dependable low-power operation using a shaded-pole design, which offers simple construction, low starting torque, and excellent reliability for small HVAC blower systems.
• 1550 RPM Nameplate Speed: Delivers consistent rotational speed within the 1501–1600 rpm range to maintain steady airflow and ensure proper performance of direct-drive fan or blower assemblies.
• 115 VAC Single-Phase Supply: Operates directly from standard household or commercial power, making the motor suitable for a wide variety of HVAC/R replacement and retrofit applications.
• Sleeve Bearing Construction: Utilizes quiet-running sleeve bearings designed to reduce friction and vibration over long operating periods, ideal for continuous-duty ventilation tasks.
• Automatic Thermal Overload Protection: Includes built-in auto-reset thermal protection to safeguard the motor from overheating, extending service life in demanding HVAC environments.
• Ring/Stud Mounting System: Features a compact mounting pattern (2-3/4 in × 2-3/4 in) that allows fast alignment and installation in blower housings without requiring special brackets.
• 3/8-Inch Shaft Diameter with 2-Inch Length: Equipped with a standard shaft size that fits common HVAC blower wheels, ensuring broad compatibility and easy field replacement.
• Open Enclosure with Junction Box: Designed with an open-air-over (OAO) housing and a 5 cu. in. junction box, enabling proper ventilation and simplified electrical access during installation.

The 3M576D delivers the reliability and precision required for stable airflow performance, continuous HVAC operation, and long-term durability in residential and commercial ventilation systems.
