ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•Core principle: Refer to the motor parameters (such as rated power, voltage, and frequency) marked on the nameplate of the air conditioner, and select a replacement motor that is suitable or meets the specifications.
•Inverter air conditioner: Brushless DC motor (BLDC) or permanent magnet synchronous motor (PMSM) is preferred, which has the advantages of accurate speed regulation, energy saving (30%-50% power saving compared with traditional motors) and low noise.
•Fixed-frequency air conditioner: Single-phase asynchronous motor is mostly used (low cost and simple structure), and it is necessary to pay attention to the speed (such as 2-pole/4-pole motor corresponding to high/low speed).
•Size adaptation: The wheelbase of the motor, the mounting hole, and the length of the shaft should be consistent with the original model to avoid vibration or abnormal noise caused by mechanical interference.
•Wiring matching: distinguish between power lines (live wire/neutral wire/ground wire) and control signal lines (such as speed regulation, feedback signals), incorrect wiring may cause short circuit or control failure.
