With the technology development of motors, HVLS fan used motors are upgrading rapidly. Now, commonly used in the market are gearbox motor Industrial ceiling fans and PM motor industrial ceiling fans.
With the technology development of motors, HVLS fan used motors are upgrading rapidly. Now, commonly used in the market are gearbox motor Industrial ceiling fans and PM motor industrial ceiling fans. Now, let’s see the differences between them.
Due to the usage of PM motor, PM motor fan is smaller than gearbox motor fan. And weight is lighter.
Matching of motor and gearbox, the structure of gearbox motor fan is not as steady as PM motor fan.
Without excitation magnetic noise and gearbox noise, PM motor industrial HVLS fan is lower noise than gearbox motor HVLS fan.
Gearbox motor fan needs to replace industrial gear oil after a running of 200-300 hours, or a stop running for one year. However, PM motor fan needs no oil. More easier to maintain.
