Refrigerator Fan Motors for Equipment Makers
Refrigeration is where small fan motors go to be forgotten — sealed in cabinets, running for years in cold, damp air, expected never to be the reason for a service call. This page serves the manufacturers who build that equipment: evaporator and condenser fan duties are described below as background; send your cabinet data and the reply assesses feasibility per project. The company does not sell retail replacement motors for household refrigerators.

This line is assessed project by project. Send your equipment drawings and duty data; the reply assesses feasibility first, and any specification, drawings, samples or pricing follow that assessment, in writing.
01 Duties
Two fans inside every cold cabinet’s story
The evaporator fan circulates cabinet air across the cold coil — the fan whose failure warms a cabinet of food before any alarm notices. The condenser fan rejects heat at the warm side, often in the least ventilated corner of the installation. Both duties share the shaded pole motor’s home profile: light aerodynamic loads, very long running hours, and a premium on the motor simply never being an event. That is why the shaded pole architecture — no capacitor, no switch, nothing to age out — has been refrigeration’s default small fan motor for generations, and why application background like this is industry-common knowledge rather than any one maker’s claim.
Nanyang’s platform profile lists fan motors among its main product lines; its official range adds external rotor designs for integrated fan units. For a refrigeration programme, send the cabinet maker’s data — airflow, envelope, ambient and duty; feasibility is assessed against that data per programme before any specification is confirmed.
For commercial refrigeration — display cabinets, cold rooms, vending — the same duties scale up in count rather than in kind: more cabinets, more fans, longer hours. The procurement emphasis shifts accordingly toward batch consistency, because a fleet of cabinets is only as reliable as its least consistent fan batch. That consistency is a winding-and-core discipline before it is anything else, and it is why the wire and core questions in our supplier guide matter even for motors this small.
02 Specifying
The refrigeration fan checklist
- Position: evaporator (cold side) or condenser (warm side); cabinet type and size class
- Air duty: airflow target and the impeller the motor drives — or the incumbent fan’s data
- Environment: temperature range, humidity and frost exposure at the motor’s position
- Electrical: market voltage and frequency (the company’s catalogue motors are wound for 220–240 V or 110 V, 50/60 Hz — catalogue-listing values, not ratings verified model by model for this fan line); any speed control
- Mechanical: shaft, mounting and rotation direction — fixed by construction in shaded pole designs, so state it up front
- Programme: quantities per shipment and year; certification requirements of the finished appliance
03 Questions
Refrigerator fan motors, answered plainly
Do you sell replacement fans for household refrigerators?
No — OEM programmes for equipment manufacturers only. We claim no compatibility with any brand’s refrigerators and do not supply the retail parts trade.
Why shaded pole for refrigeration?
Simplicity that survives the environment: no capacitor to age, no switch to fail, tolerant of the cold and damp the duty involves. The applications guide covers the reasoning in full.
Can one programme cover evaporator and condenser fans?
Send both positions’ data in one enquiry; feasibility for both positions is assessed together, and the reply says whether a common specification approach is feasible before any specification is proposed.
Specify the fan that gets forgotten — properly
Position, air duty, environment and volumes, with your cabinet data. The reply assesses feasibility per programme, in writing, before any specification is confirmed.
