As a vital component of your equipment's indoor blower assembly, this motor plays a critical role in system safety and performance by facilitating the smooth and reliable operation required to push treated air through your system. Maintaining a strong and properly functioning blower motor is essential for balanced temperature regulation, preventions against evaporator coil freeze-ups, and the overall efficiency of your system.\u003c\/p\u003e\n\u003cp\u003eOperating on a 208-230V electrical configuration and supporting both 50 and 60 Hz frequencies, this powerful 1 HP motor produces variable speeds up to 1200 RPM while maintaining constant torque. Opting for a Genuine OEM Trane replacement part matters immensely because it guarantees exact electrical compatibility and a precision fit within your existing 48-frame housing. This precise tolerance ensures no unwanted vibrations, significantly reduces bearing wear, and completely eliminates the guesswork or modification demands often required when resorting to generic aftermarket motors.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eKey Features and Function:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eAirflow Management\u003c\/strong\u003e: Features advanced constant torque technology for precise control, delivering highly optimized and consistent system performance across varying load conditions.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eGenuine OEM Reliability\u003c\/strong\u003e: Factory-engineered and tested by Trane to meet strict performance and durability standards, extending the overall lifespan of your unit.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eDirect-Fit Design\u003c\/strong\u003e: Designed with a standard 48-frame body to fit perfectly into belly-band or standard equipment mounts without aggressive modifications.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eHeavy-Duty Build\u003c\/strong\u003e: Built with a durable ball bearing construction to convert energy reliably and efficiently while maintaining quiet operation.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eProduct Details and Key Specifications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e: MOT20943 (Replaces MOT17195)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e: Trane \/ American Standard (Genuine OEM)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePart Type\u003c\/strong\u003e: Constant Torque Blower Motor\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eVoltage\u003c\/strong\u003e: 208-230V\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eHP \/ RPM\u003c\/strong\u003e: 1 HP @ 1200 RPM\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePhase \/ Hertz\u003c\/strong\u003e: Single-phase (1PH) \/ 50\/60 Hz\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRotation\u003c\/strong\u003e: Clockwise (CW)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Weight\u003c\/strong\u003e: ~12.0 lbs\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e🛠️ \u003cstrong\u003eHVAC Depot Pro Tip: Secure Your Mounts\u003c\/strong\u003e\n\u003c\/h2\u003e\n\u003cp\u003eWhen replacing a high-torque 1 HP motor like the MOT20943, always double-check the torque and alignment on your belly-band brackets or mounting bolts.
