Y3HTF Series Fire High Temperature Smoke Exhaust Fan Special MotorDetailed product description：

The Y3HTF series fire high-temperature smoke exhaust fan special motor has the characteristics of high efficiency and flat curve, which is conducive to energy conservation. The machine adopts a direct drive system with an electric motor, which can be driven at a single speed according to the different requirements of high-end civil buildings, in order to achieve the purpose of ventilation, exhaust and high-temperature smoke exhaust during firefighting use. Widely applicable to high-end civil buildings, ovens, underground garages, tunnels, and other occasions.

The Y3HTF series fire high-temperature smoke exhaust fan special motor bearings are selected as low vibration and low-noise bearings 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. Machine seat sizes 160 and above use inner and outer cover structures, and are fixed axially with retaining rings at the bearing locations, effectively preventing 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.
