The Trane MOT18993 is a compact, 3-speed motor designed to provide variable airflow control in Trane HVAC equipment. Unlike a standard single-speed motor, it offers three distinct speed settings (high, medium, low). This flexibility allows for adjustments based on your heating or cooling needs, potentially improving comfort and system efficiency. #Trane #MOT18993 #3SpeedMotor #Tran... https://www.partshnc.com/mot18993-trane-115hp-115v-1080rpm-3spd-motor
