Trane MOT9801 Motor

The Trane MOT9801 is a high-performance, 3 HP blower motor designed for heavy-duty commercial HVAC applications. Engineered for multi-tap versatility, this three-phase HVAC motor supports 208-230/460V AC line power, making it a drop-in OEM replacement motor for various Trane and American Standard air handlers and rooftop units. Operating at a nominal 1740 RPM, this 56HZ frame motor features an Open Drip Proof (ODP) enclosure to maximize airflow and thermal dissipation during continuous operation.

For technicians managing large-scale air distribution, the Trane MOT9801 motor includes a rigid base mount and permanently lubricated ball bearings to ensure lateral stability and minimal mechanical friction. With a 1.15 service factor and dual-frequency compatibility (60Hz default / 50Hz capable), this motor is the industrial standard for maintaining static pressure in critical environments. It utilizes a 7/8" keyed shaft and is designed for CCW rotation to match specific blower wheel configurations.

Key Benefits:

• Precise Voltage Versatility: Dual-voltage 208-230/460V capability eliminates the need for external transformers in most commercial cabinets.
• Efficient Thermal Management: The ODP enclosure and Class B insulation prevent winding overheating during peak demand cycles.
• OEM-Spec Fitment: Built to the exact mechanical specifications of the 56HZ frame for rapid installation without bracket modifications.
• Reliable Drive Performance: The 3 HP motor output provides the torque necessary for high-static blower assemblies.

Common Questions: What is the frame size and shaft diameter for the MOT9801? This motor utilizes a standard 56HZ frame with a 7/8 inch keyed shaft, ensuring compatibility with standard Trane blower pulleys and couplings. Can this motor be used on 50Hz power systems? Yes, the Trane MOT9801 is rated for dual-frequency operation, allowing it to function at 50Hz with adjusted performance specs (typically 1450 RPM) where required. Is the rotation reversible on this unit? While most Trane OEM blower motors are configured for specific CCW or reversible rotation, contractors should verify the lead assembly and nameplate rotation diagram before final mounting.
