Our SD-DOB Series HVLS Industrial Ceiling Fan adopt Permanent Magnet Direct Drive Motor with outer rotor design, it is very energy saving and working quite with low noise. HVLS PMSM integrated machine adopts the international leading field-oriented vector control technology, synchronous motor control technology, and static motor parameter self-learning algorithm, which can match various types of PMSM motors. The matching accuracy is high, the output power factor is high, the energy-saving effect is good, the motor running current is small, and the current fluctuation is small, so the motor temperature rise is small.
1)More energy saving effect.
2)Operating noise is significantly reduced.
3) Service life and reliability are significantly improved.
4)reduction gear box is eliminated ,pollution due to lubricant leakage does not occured.
5)Maintenance-free for the entire life.
6)A standard factory building of 10,000 square meters only needs to install 5-10 large-scale 7.3 meter fans, which is more than 70% energy-efficient than traditional distributed small fans.
It is used more for medium size HVLS fan is a very cost-effective optional choice.
Compared with the traditional brush motor, induction motor, it has a better dynamic performance, higher efficiency, longer life, lower noise, free maintenance, etc.
Our PMSM motor adopt unique rare earth NdFeB magnets, rotor and stator, and with its unique design, the overall dynamic performance improved significantly, 300N.M the highest torque in the world, higher efficiency and better stability.
Top level electrical configuration in HVLS industry, famous brand electrical components, with building safety protection module which will shut down the output automatically in case of some accidents.
Servo drive system can make fan have a fast reaction with DSP control core and inner complex control algorithm. In addition, it has continuously variable, precise localization and the protection system with over voltage,over currents.
Using Japanese NSK high temperature bearing bearing, high precision, strong heat resistance, can be used for a long time without maintenance. The advantage is that the starting friction is small, and the difference between the sliding friction is also small, and it can be used even in a negative clearance (preload state).
Adopt imported special high strength aircraft grade magnesium, PVFD processed in surface, and aerodynamics fan blade design.
Made of high quality aviation aluminum magnesium alloy, anodized with T6 heat treatment, strengthening support system inside which increases the strength of fan blade and avoids the drop of fan blade tail and the loss and fatigue of fan blade to connecting pieces completely.
1. Suitable for any building with a ceiling height of 3.5 meters or more.
2. The load bearing capacity of the roof structure should be more than 150kg, the max. total running weight of the fan equipment is about 125kg.
3. Make sure that the fan is installed without chandeliers or other obstructions.
4. It’s not recommend for installation at the site with heat sources or lampblack occasion.
