Speaking of commercial fans, we have to mention the development history of commercial fans. Commercial fans are large diameter, large air volume, and low speed (speed below 100RPM) ultra-large variable frequency control fans. Its development can be summarized as the following three stages. Commercial fans are commercial fans that use three-phase asynchronous motors.
The speed is controlled by a gear reducer, which is a very backward method. It is large in size, heavy in weight, high in energy consumption, noisy, requires frequent maintenance, has a very short lifespan, and its safety is not guaranteed. Fan blades often fall off and fly out due to excessive shearing force. There are still many products of this type on the market today, and because of their low prices, they may still fool some people who don`t understand.
Commercial fans are commercial fans that use permanent magnet external rotor motors. Compared with the previous generation of commercial fans, they are smaller, lighter, consume less energy, make less noise, require no maintenance, and are safer. It has taken a big step forward in the development of commercial fans. However, some shortcomings have also been discovered in long-term use. Because the heat dissipation and protection of the motor with the outer rotor structure have great defects, the phenomenon of demagnetization and burning of the motor often occurs due to temperature rise. The life of the motor without protection level is also very short. short.
Commercial fans are commercial fans that use
Gym Fan. Based on the first two generations of commercial fans, we took the advantage of them and made up for their shortcomings and took the lead in launching the third generation of Gym Fan. It is small in size, light in weight, low in power, low in noise, maintenance-free, safer, up to IP64 waterproof and dustproof, has a working efficiency of over 95%, a service life of more than 15 years, and a comprehensive cost-effectiveness that far exceeds the previous two generations.
