As we all know, direct drive fan becomes a new trend of the HVLS ceiling fan. But there are so many manufacturers that make fans, how do you choose a good product?


As a manufacturer with 8 years of experience in manufacturing fans and 6 years of experience in manufacturing direct drive fans, we suggest you use the direct drive fan with inner rotor structure..


Direct drive fans on the market mainly have two structures. One is the inner rotor structure, and the other is the outer rotor structure.


The internal rotor structure means that the fan blades are under the motor and connected with the chassis. The chassis is connected with the output shaft. The motor is at a standstill during operation, and the output shaft drives the fan blades to rotate. The advantage of this is that the entire motor forms a sealed structure, and the protection level can reach a high level. For example, the protection level of the direct drive fans of Qixiang is IP64, and it can be used normally on rainy days.


The outer rotor structure means that the fan blades are directly mounted on the motor, and the motor drives the fan blades to rotate together. At this time, the load of the motor is large, and the motor heats up quickly. If the temperature is too high, the NdFeB material in the motor will lose its magnetism. In order to reduce the temperature of the motor, there are usually vents on the top and bottom of the motor. The long-term operation will cause moisture and dust to enter and shorten the service life.


Well-known brands at home and abroad, such as the famous brand Marco Air that first created the HVLS fan, the well-known American brand big ass fan, hunter fans, and the British Elta fans, all use direct drive fans with an inner rotor structure. It can be seen that the inner rotor structure is the best choice for direct drive fans.
