Rated for multi-horsepower operation from 1\/4 to 1\/2 HP, it runs on 120\/240 volts single phase at 50\/60 Hz and delivers variable speed performance across 5 selectable speeds with a nominal RPM range of 1075 variable. The motor features Bluetooth connectivity and pairs with the MARS Azure ECM app for commissioning, diagnostics, and speed adjustment without additional wiring. It is installed by licensed HVAC technicians as a direct replacement for standard ECM variable-speed and constant-torque blower motors in forced-air systems.\u003c\/p\u003e\u003cp\u003eThe mars-10856 fits belly-band mount installations using a NEMA 48 frame. It is suited for residential gas furnaces, air handlers, and fan coil units requiring variable speed or constant torque blower motor operation. The OAO (open air over) enclosure supports standard forced-air cooling environments. Bidirectional rotation (REV+FWD) allows the motor to be configured for a wide range of blower assemblies without sourcing a separate unit for shaft orientation. No capacitor is required for operation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eECM technology provides variable speed and constant torque operation across 5 speeds\u003c\/li\u003e\n\u003cli\u003eBluetooth-enabled via the MARS Azure ECM app for commissioning and speed control\u003c\/li\u003e\n\u003cli\u003eMulti-rated 1\/4 to 1\/2 HP supports a range of blower load requirements\u003c\/li\u003e\n\u003cli\u003eBidirectional rotation (REV+FWD) accommodates multiple blower assembly configurations\u003c\/li\u003e\n\u003cli\u003eRedundant electronic thermal protection circuits for motor longevity\u003c\/li\u003e\n\u003cli\u003eNo capacitor required — simplifies replacement and reduces parts count\u003c\/li\u003e\n\u003cli\u003eCUL listed; Insulation Class B rated for ambient temperatures up to 55 degrees C\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-drive OEM-style replacement for variable speed ECM and constant torque blower motors in NEMA 48 frame belly-band mount applications.

Disconnect and lock out all power to the air handler or furnace before removing the existing motor. Belly-band mounting hardware from the original motor is typically reused; confirm band diameter matches the NEMA 48 frame before fastening. Use the MARS Azure ECM app during commissioning to set speed profiles and verify operation in accordance with equipment manufacturer specifications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: ECM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower (Max)\u003c\/strong\u003e: 1\/2 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Rated Horsepower\u003c\/strong\u003e: 1\/4 to 1\/2 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 120\/240 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Load Amps (FLA)\u003c\/strong\u003e: 6.4 \/ 3.8 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHz\u003c\/strong\u003e: 50\/60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeeds\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRPM Range\u003c\/strong\u003e: 1075 variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotation\u003c\/strong\u003e: REV+FWD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNEMA Frame Size\u003c\/strong\u003e: 48\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure\u003c\/strong\u003e: OAO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount\u003c\/strong\u003e: Belly Band\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing\u003c\/strong\u003e: Ball\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Length\u003c\/strong\u003e: 4.94 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Protection\u003c\/strong\u003e: Redundant Electronic Control Circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Class\u003c\/strong\u003e: B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmbient Temperature Rating\u003c\/strong\u003e: 55 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacitor Included\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CUL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 14.90 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 7.50 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7.10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.94 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Vietnam\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MARS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: mars-10856\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MARS","offers":[{"title":"Default Title","offer_id":51138394521906,"sku":"MARS-10856","price":416.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532499.jpg?v=1778255154","url":"https:\/\/voomisupply.com\/products\/mars-mars-10856-ecm-direct-drive-blower-motor-1-2-hp","provider":"Voomi Supply","version":"1.0","type":"link"}
