Share supply, speed, control, mounting and fan geometry.","domi_cat_intro":"External rotor motors are evaluated as part of a refrigeration fan or air-cooler assembly, with mechanical construction, fan geometry, electrical input and control requirements considered together. This category is for buyers who need an external rotor direction for refrigeration fans, air coolers, condensers or HVAC applications. Provide the fan, mounting, envelope, airflow or pressure requirement, voltage, frequency, control method, rotation, environment and existing reference. External rotor construction should not be treated as a substitute for a complete motor specification.","domi_cat_image_detail":6477,"domi_cat_image_application":6476,"domi_cat_visual_detail_text":"An external rotor motor places the rotating assembly around the stator and is commonly evaluated with the fan, mounting and airflow arrangement as one system. Confirm voltage, speed, rotation, impeller or fan interface, mounting dimensions and control requirements.","domi_cat_visual_application_text":"External rotor motors can be integrated into air coolers, condensers and HVAC or refrigeration fan assemblies. The application view helps buyers check fan diameter, installation depth, airflow direction, service access and the actual electrical duty.","domi_cat_heading_selection":"External Rotor Motor Selection Questions","domi_cat_selection":"Fan duty and geometry | Provide fan diameter or wheel, airflow or pressure requirement, duty cycle and rotation | Connects the motor review to the real load.\nElectrical and control interface | Share voltage, frequency, phase, control signal, speed requirement and protection details | Confirms compatibility.\nMounting and envelope | Provide fixing points, shaft or hub, surrounding clearance, air direction and service access | Confirms the external rotor assembly can fit.","domi_cat_heading_structure":"External Rotor Motor Structure and Interface","domi_cat_structure":"External rotor construction | The category identifies an external rotor motor direction; confirm the exact rotor, stator, fan, mounting and enclosure arrangement from current product data.\nFan integration | External rotor motors are often evaluated with the fan or air-cooler assembly, so provide fan geometry, air path, rotation and clearance.\nTechnology overlap | External rotor describes mechanical construction and may coexist with EC technology; confirm control and supply requirements for the exact model.\nExternal rotor motor selection | Confirm the fan assembly, installation envelope, rotation, control requirements and mechanical interface | External rotor describes a construction direction and does not replace the complete motor specification.","domi_cat_heading_specifications":"External Rotor Motor RFQ Parameters","domi_cat_specs":"Parameter | Information to provide | Why it matters\nApplication | Refrigeration fan, air cooler, condenser, evaporator or HVAC equipment | Establishes the assembly context.\nFan duty | Fan size, airflow or pressure, rotation and duty cycle | Supports motor-load review.\nElectrical and control | Voltage, frequency, phase, signal, speed and protection requirement | Confirms interface.\nMechanical interface | Mounting, fan or wheel connection, envelope, clearance and air direction | Confirms fit.\nEnvironment and reference | Temperature or moisture context, old motor, drawing, photos and quantity | Supports replacement and quotation review.","domi_cat_heading_comparison":"External Rotor and EC Motor Comparison","domi_cat_comparison":"Choice area | What changes | Confirm before choosing\nExternal rotor motor | Mechanical rotor construction affects the fan and mounting arrangement | Confirm geometry, mounting, supply, rotation and clearance.\nEC motor | Motor and control technology adds input and control requirements | Confirm signal, speed, supply, mounting and fan compatibility.\nCombined configuration | External rotor and EC are not necessarily opposite categories | Ask for the exact motor architecture and control data before comparing.","domi_cat_heading_applications":"External Rotor Motor Applications","domi_cat_applications":"Air coolers | The motor must align with fan wheel, room airflow, mounting and service access | Provide air path, fan size, duty, supply and clearance.\nCondenser fans | Heat-rejection duty and ambient environment shape the assembly review | Share condenser layout, fan geometry, motor input and mounting.\nHVAC and refrigeration equipment | Electrical control, fan arrangement and enclosure need to fit the complete unit | Provide system drawing, airflow, control and quantity data.","domi_cat_heading_quality":"External Rotor Motor Verification Checklist","domi_cat_quality":"Motor architecture confirmation | Confirm external rotor construction, fan integration, electrical input, control and mounting details.\nAssembly fit check | Match fan geometry, rotation, fixing points, envelope, air direction and clearance.\nFunctional acceptance | Agree the applicable running, rotation, noise, electrical or other project-specific tests before release.","domi_cat_heading_procurement":"Information to Send for an External Rotor Motor RFQ","domi_cat_procurement":"Fan and equipment reference | Send the fan or air-cooler model, photos, drawing and application | Provides assembly context.\nDuty and environment | Provide airflow or pressure, operating condition, ambient, duty cycle and rotation | Supports the motor-load review.\nElectrical and mounting | State voltage, frequency, control, fixing points, fan connection, envelope and clearances | Confirms compatibility and fit.\nQuantity and documentation | Share quantity, drawing revision and inspection requirements | Supports quotation detail.","domi_cat_heading_faq":"External Rotor Motor Buyer FAQ","domi_cat_faq":"Is external rotor a complete motor specification? | No. It describes a mechanical construction direction; supply, control, speed, fan geometry, mounting and environment still need to be confirmed.\nCan an external rotor motor be EC? | It can be possible for the two descriptions to coexist, so request the exact architecture and control data rather than treating them as mutually exclusive.\nWhat should I send for an air-cooler motor? | Provide fan geometry, airflow or pressure, mounting, rotation, supply, control, environment and the existing reference.\nHow do I match a replacement external rotor assembly? | Send photos or drawings with fan, fixing, envelope, air direction, wiring and quantity details.\nWhat should be approved before production? | Approve the motor and fan interface, electrical data, mounting and applicable functional checks.","domi_cat_heading_resources":"External Rotor Motor Resources","domi_cat_resources":"Industrial Air Cooler Air Throw | https:\/\/domirefrigeration.com\/industrial-air-cooler-air-throw\/ | Use it to connect fan and motor selection with room coverage.\nFan Coil Unit Selection | https:\/\/domirefrigeration.com\/fan-coil-unit\/ | Use it to review fan, coil, airflow and control interfaces.\nCold Room Evaporator Fan Selection | https:\/\/domirefrigeration.com\/cold-room-evaporator-fan-selection\/ | Use it to organize motor and fan duty inputs.","domi_cat_source":"Built from the current category name and description, the current Motors structure, Domi refrigeration article URLs, the Domi archive template, and cautious motor-selection guidance.
