YFF series mixed flow diagonal fan dedicated motorDetailed product description：

The YFF series of mixed flow and diagonal flow fan motors are designed and matched motors for mixed flow and diagonal flow fans. They have the advantages of high efficiency, compact structure, low noise, small size, and easy installation. When installed in mixed flow and diagonal flow fans, their air volume is larger than that of centrifugal fans of the same model. They are widely used in high-end civil buildings such as hotels, restaurants, shopping malls, office buildings, sports centers, etc., for ventilation and air exchange in industrial and mining enterprises.

The motor bearings are selected as low vibration and low-noise bearings specifically designed for electric motors. Double sided sealed bearings are used for machine seat sizes 132 and below, and waveform spring washers are installed at the shaft extension end to provide moderate pressure against the bearings, effectively suppressing the vibration and noise generated during motor operation. For machine seat sizes 160 and above, inner and outer cover structures are used, and retaining rings are used for axial fixation at the bearing locations to effectively prevent axial movement of the motor rotor.

In order to ensure the safe and reliable operation of the motor, the bearing structure of motors with a base size of 160 and above is equipped with an oil injection and discharge device. For motors with a base size of 250 and above, a position for bearing temperature monitoring sensing elements is reserved.
