The quality of the blower motor and the micro-motor directly affect the performance of the HVAC, such as the size of the air volume, the size of the noise, the stability of the movement mechanism, whether the damper movement is normal, etc. are all related to the selection of these two components.

The performance evaluation of the air-conditioning system must include the performance evaluation test of the blower. The relevant approval tests and methods have different standards according to different OEMs. It is necessary to judge from various data, such as rated current, starting torque, maximum starting voltage, braking Accuracy, rotational speed, motor running noise, motor locking, durability, etc.

To choose a motor with good performance, the supplier needs to ensure that the production line return is 0PPM and the warranty return is less than 50 PPM.
