Smart Control Direct Drive Motor Fan
Fan blade:
It is made of aluminum and magnesium alloy extruded and stretched, and has the advantages of high strength, good toughness, light weight, long life and safe operation.The fan blade surface is treated with T5+bright surface oxidation treatment, which enhances the corrosion and oxidation resistance of the fan blade and can cope with special environmental operations.
Tail:
When thefan blade is running, the air will generate vortex at the end of the aerofoil fan blade. The tail wing can eliminate this part of energy loss, stabilize the fan operation, and make the air flow more consistent with the aerodynamic principle.
The control system adopts the closed design of IP66, which is dustproof, waterproof, moisture-proof and can withstand high temperature indoor and outdoor harsh environment,
· The system is no position vector control, anti- electromagnetic interference, anti-radiation, small size, light weight, beautiful appearance.
·System function is simple,4 buttons easy to operation(start, stop,speed up,slow down).
·System with overvoltage,undervoltage,voltage loss regulation, current, lack of phase, overload, collision, overheating, lightning,abnormal protection.
·Can be customized intelligent control mode: WLAN, Bluetooth, 4G, time, PID, centralized control.
Number of Leaves Specification Working Principle
According to different environmental requirements, we can provide fan products with five fan blades and six fan blades with two different specifications, which can customize the most suitable solutions according to the actual application environment requirements ofusers.
The new self-developed external rotor motor with large torque and permanent magnet synchronization replaces the traditional motor + gearbox reducer, achieving a high degree of integration and improving reli-ability and transmission efficiency.
At the same time, the permanent magnet synchronous external rotor motor is adopted, with its own IMU configuration, to achieve the ESC active control strategy + coordinated regenerative braking strategy, driven by the motor directly;Any torque recovery or auxili-ary braking within the peak torque can be satisfied.Aluminum alloy material is adopted in many parts to realize lightweight design.
