A large ceiling fan is a low energy consumption ventilation and cooling device that has been favored by many customers. However, due to the fact that the ceiling fan is suspended at high altitude, maintenance is relatively difficult. Therefore, many customers are concerned about whether the large ceiling fan will be hindered in rotation after long-term use. Do they need to replace the lubricating oil every few months like maintaining a car? Now let's answer this question for everyone.

We know that there are currently two main types of large ceiling fans on the market: electric motors.

One type is a traditional gear reduction motor, which works by using electrical energy to drive a size driven motor. Lubricating oil is needed in the gearbox for lubrication and heat conduction, which is exactly the same as the traditional motor's gearbox that needs to leave exhaust holes for the gas generated by the gearbox's rotation to be discharged. Like all power devices that use lubricating oil,

This type of gear reduction motor requires regular replacement of lubricating oil for large ceiling fans. In a semi normal usage environment, lubricating oil can be made smoother every 2-3 years. In harsh environments, it needs to be replaced every 1-2 years. To replace the lubricating oil, it is necessary to follow the regulations on the gear machine and use the recommended lubricating oil model.

The second type is the popular brushless direct drive motor in recent years, which adopts the principle of electromagnetic induction. The motor contains magnetic components and coils, and there is no lubricating oil present. Therefore, this type of brushless direct drive fan does not require the replacement of lubricating oil.

When using a large ceiling fan, customers need to distinguish which type of motor the fan is. If it is a gear reducer motor, it is necessary to regularly replace the lubricating oil according to the motor's maintenance instructions and usage environment.
