PRODUCT DESCRIPTION
Motor CorTec PMSM motor has the advantages of high starting torque, short starting time and high overload capacity, with specialized winding machine, complete testing equipment, strict and effective quality assurance system, can fully ensure low temperature of inside motor, and guarantee motor temperature. Maintenance Free CorTec PMSM motor requires no traditional oil changes. No more costly maintenance and leakages. VFD Special designed for HVLS Fan Industry OUTLINE Based on the Blade Element Momentum Theory, CorTec has gone through repeated designs to identify the optimal curve and angle of the fan blade. If you wish to preview the actual appearance, please directly contact us (the actual dimensions are confidential and have been patented) CorTec compared dozens of different aerodynamic designs using ANSYS FLUENT simulations and identified the shape that yielded the maximum airflow under equivalent power conditions. As illustrated in the following images, which depict two distinct fan blade profiles, the wind speed heatmaps generated by their rotations are vastly different. Specifically, the airflow volume on the left is 5.7% greater than that on the right Structure The internal structure of the CorTec fan blade has a special design: Beam connecting part CorTec special design, with 8mm thickness plate, and special bend, robot welding technology, can totally ensure fans safety to avoid any accident happened. CorTec can provide wind flow simulation (CFD) for VIP clients or Large Projects, which requires you to provide 3D drawings of the project. Our engineers will select the appropriate size of fans and calculate the number of fans needed for the project to achieve the most suitable ventilation effect while being more economical.
Simple Installation: Integrated design of the control cabinet and variable frequency drive (VFD) eliminates the need for secondary installation.
High Compatibility: Compatible with both permanent magnet synchronous motors and asynchronous motors.Easy Maintenance: Wear parts are easy to clean and replace.
Comprehensive Components: Includes a speed control knob and a main circuit power breaker.
Quiet Comfort: Carrier frequency up to 16kHz ensures a quiet, natural acoustic experience.
Smooth Operation: Operates smoothly, allowing you to enjoy the sensation of a natural breeze.
Auto-Tuning Free: Supports auto-tuning-free operation for synchronous motors.
Comprehensive Protection: Features up to 33 protection functions, including impact protection, overcurrent, overvoltage, overload, and ground fault protection.
High Flexibility: Versatile unit; switch between controlling synchronous or asynchronous motors simply by adjusting parameters.
Centralized Control: Optional wireless module available for wireless transmission and centralized control.
VVC Control Algorithm: Based on a new VVC control algorithm for permanent magnet synchronous motors, enabling perfect control without the need for auto-tuning.
Overload Protection: Proprietary current-limiting algorithm prevents motor overcurrent and protects against demagnetization caused by overheating due to overload.
Impact Protection: If the fan blades are struck, the VFD can stop and cut off output within as little as 100ms.
4G IoT Connectivity: Enables IoT-based control, including start/stop, speed adjustment, and system monitoring.
It contains two connected reinforcement ribs and four unconnected reinforcement ribs, which makes the fan blade lightweight and more resistant to fracture
When the fan blade is connected to the plug-in and the nut and nut tighten the fan blade and the plug-in, the two "E-shaped" reinforcement ribs have a certain deformation ability. When the fan blade is subjected to the tightening force from top to bottom, the reinforcement ribs will bend slightly, which can not only ensure the close connection between the plug-in and the fan blade, but also ensure the structural strength of the fan blade.
