The Trane MOT21481 Programmed Motor is an OEM constant-torque ECM blower motor designed for compatible Trane HVAC equipment. This motor is specified as 3/4 HP, 208-230V, single-phase, 60 Hz, with a programmed operating range of approximately 1050-600 RPM and CCW rotation. The MOT21481 is also the current replacement for Trane MOT16685.
This Trane ECM blower motor includes the programmed control configuration required for specific Trane air-moving applications. Because ECM motors depend on factory programming as well as electrical and mechanical specifications, do not substitute a motor based only on horsepower, voltage, or RPM.
Before ordering, verify the complete equipment model and serial number, original motor number, voltage, phase, rotation, mounting arrangement, shaft configuration, and control requirements.
