Rated at 3\/4 to 1\/3 HP with a synchronous speed of 1075 RPM and a 10-pole configuration, this motor delivers efficient, quiet airflow control suited to multi-speed fan coil and air handler systems. The open protected air-over (OPA) enclosure allows airflow across the motor for cooling in ducted installations. Operating on 115\/208-230 volts, 60 Hz, single-phase power, the unit is reversible and compatible with 16-pin ECM control modules. Its 5.6-inch diameter frame fits standard air handler cutouts.\u003c\/p\u003e\n\u003cp\u003eThis motor is intended for variable speed blower applications in forced-air HVAC systems. The ECM design provides electronically commutated motor control, reducing energy consumption compared to traditional PSC motors. Licensed HVAC technicians typically install this unit as a direct OEM-style replacement in residential air handlers and fan coil units where a 16-pin ECM interface is specified. The reversible rotation feature supports a range of blower configurations without requiring additional components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eECM variable speed operation for efficient, electronically controlled airflow\u003c\/li\u003e\n  \u003cli\u003e3\/4 to 1\/3 HP dual-rating with 1075 RPM and 10-pole design\u003c\/li\u003e\n  \u003cli\u003eReversible rotation for flexible blower configuration\u003c\/li\u003e\n  \u003cli\u003eOPA enclosure rated for open, air-over ducted installations\u003c\/li\u003e\n  \u003cli\u003e115\/208-230V dual voltage compatibility, 60 Hz, single phase\u003c\/li\u003e\n  \u003cli\u003e16-pin ECM module interface for direct replacement use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style ECM variable speed replacement motor for residential and light commercial air handler and fan coil blower assemblies requiring a 16-pin ECM interface, 5.6-inch diameter frame, and 1075 RPM operating speed.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Disconnect and lock out all power to the air handler before removing the existing motor or module. Verify that the replacement motor rotation direction and shaft orientation match the existing blower assembly before securing the motor. Consult the equipment manufacturer wiring diagram and applicable NEC requirements when reconnecting the 16-pin ECM harness.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower\u003c\/strong\u003e: 3\/4 to 1\/3 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpeed\u003c\/strong\u003e: 1075 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoles\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: ECM Variable Speed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 115\/208-230 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: Single Phase\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure\u003c\/strong\u003e: OPA (Open Protected Air-Over)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 5.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotation\u003c\/strong\u003e: Reversible\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnector\u003c\/strong\u003e: 16 Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: US MOTORS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: m055ayz3660015b\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"US MOTORS","offers":[{"title":"Default Title","offer_id":51268777509170,"sku":"M055AYZ3660015B","price":618.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308911986.jpg?v=1780705456","url":"https:\/\/voomisupply.com\/products\/us-motors-m055ayz3660015b-ecm-variable-speed-motor-3-4-hp","provider":"Voomi Supply","version":"1.0","type":"link"}
