HD46MQ134
The Carrier HD46MQ134 is a Motor Blower and an Electronically Commutated Motor meant to be used in most HVAC applications. It operates by applying an outdoor controller panel to manage the air movement in the course of the heating or cooling circuits. This single phase motor is 3/4 horsepower and has ball-bearing construction for quiet and reliable operation. It runs at 1050 RPM and is suitable for both 50Hz and 60Hz electrical supply systems. Due to its small dimensions, it measures 11” x 11” x 12” so it is perfect for HVAC systems. ECM blowers have further advantages over the regular AC motors in the automobile, these include the following, enhanced efficiency, low noise, and electrical airflow regulation.
