1/4 HP 115 V 1 PH 1075 RPM Marathon Motors Unit Heater Motor BL3-RS-OP-56-4-B-D-.33-RS

The motor powers a fan or blower that forces air over a heating element (electric coil or hot water/steam coil), distributing warm air into the space. Types of Motors Commonly Used: PSC (Permanent Split Capacitor) Motors: Energy-efficient and commonly used in smaller units. ECM (Electronically Commutated Motors): More advanced, variable-speed, and energy-efficient. Split-phase or Capacitor-start Motors: Typically used in heavy-duty or high-torque applications. Key Specifications: Voltage: 115V (depends on the unit model) Horsepower (HP): Ranges from 1/20 HP to 1 HP Speed (RPM): Usually between 825 – 1075 RPM Frame Size: Indicates mounting style and compatibility
