Electronically Commutated Motor
The newest generation of ECM series motors are designed with advanced electronic control technology, make the motor efficiency greatly increased, the external structure design of ECM series motors will maintain the similar external structure design as YZF series motors, motor accessories such as fan blades, rings or grids, brackets for ECM motors are the same as YZF series* , therefore ECM series motors can completely replace the YZF series motors without any other changes.
Comparing with YZF series motors, ECM motors display an obvious advantage in energy saving, saving up to 70%, it can greatly reduce the electricity cost for motor operation and carbon dioxide emissions.
Not only that, due to the heating of ECM series motors themselves are very low, it would lead to the entire refrigeration system works more efficient and make motor running more stable and reliable.
Main features
High safety class
ECM motors adopt thermoplastic for housing and the protection level has achieved class II, therefore the earth conductor will be unnecessary and the cost will be reduced.
High protection class IP65
Enclosed motor design will have a better moisture-proof effect and make it possible to work in the high humidity and dust environment.
High reliability
The dual-chamber design(Patented) leads the motor can be effectively separated from electronic control area in order to avoid dust and humidity enter into the cavity of control board.
Product Details
Domi Refrigeration supplies Electronically Commutated Motor for OEM buyers who need a drawing-driven component, stable repeat production, and a supplier that can discuss size, material, testing, and packaging before release.
For motor projects, voltage, rotation, shaft size, mounting pattern, wiring, and sound target should be checked before sample approval.
Where this product fits
This product is used wherever the cabinet needs reliable airflow, consistent speed, and stable running performance.
- high-efficiency fan systems
- cabinet airflow control
- OEM refrigeration assemblies
Materials and build options
EC motor builds normally use a controlled electronic drive, winding system, rotor, housing, and matched electrical interface. The exact housing and connector layout should follow the approved sample.
Confirm motor body size, mounting pattern, connector position, shaft detail, and controller interface before release. EC motors are often defined by the exact electrical and mechanical match.
Specification guidance
| Item | Guidance |
|---|---|
| Main materials | Electronic drive, winding system, rotor, housing, and electrical interface matched to the OEM cabinet. |
| Dimensions | Confirm body size, mounting points, connector position, shaft detail, and controller interface. |
| Refrigerant / medium | This is not a refrigerant pressure part. Confirm electrical environment, control method, airflow target, and installation conditions instead. |
| Pressure / electrical note | Not applicable as a pressure-bearing component; electrical and environmental compatibility should be confirmed instead. |
| Testing | Release checks may include rotation, current draw, noise, and controller response, together with a final visual and packaging check. |
| MOQ | MOQ depends on the driver configuration and order quantity. Sample confirmation is usually the best first step. |
| Lead time | Lead time depends on the controller spec, quantity, and the level of electrical matching required. |

Testing and release checks
Release checks may include rotation, current draw, noise, and controller response, together with a final visual and packaging check.
For OEM programs, keep the approved electrical spec and mechanical drawing together so repeated orders stay stable.
FAQ
Can you confirm the size from a sample or photo?
Yes. A sample or control-board reference helps confirm whether the motor can be matched safely.
How do you confirm refrigerant, pressure, or operating conditions?
For EC motors, the important checks are voltage, control mode, electrical load, and installation environment.
What is needed for MOQ and lead time confirmation?
Quantity, controller type, and approval status are the main MOQ and lead time inputs.
