Carrier HD46MM122 Blower Motor, PWM ECM, 3/4 HP, 115V for Forced Air HVAC Systems

Condition: New

The Carrier HD46MM122 is a high-efficiency replacement blower motor designed for residential HVAC systems. This electronically commutated motor (ECM) offers superior performance and energy savings compared to traditional AC induction motors. ECMs, while visually similar to traditional motors, operate without brushes, reducing friction and noise, leading to smoother operation and increased efficiency. This 3/4 horsepower motor is compatible with 115-volt electrical systems and features variable speed functionality, allowing it to adjust its airflow based on the system’s demand. This variable speed capability translates to quieter operation during periods of lower demand and increased airflow when needed, ultimately contributing to greater comfort and energy savings. The dimensions of the motor are approximately 12.5 x 12.5 x 11.5 inches, and it weighs approximately 18.51 lbs.
