Fan-specific VDS



The VDS developed and designed for fans such as air cooling islands, cooling towers, and powder separators adopts low-speed and high-torque permanent magnet synchronous motors (PMSM) to directly drive fan blades; completely abandons the "asynchronous motor + gearbox " < /span> structure, precise shortening of the drive chain.

The VDS developed and designed for fans such as air cooling islands, cooling towers, and powder separators adopts low-speed and high-torque permanent magnet synchronous motors (PMSM) to directly drive fan blades; completely abandons the "asynchronous motor + gearbox " < /span> structure, precise shortening of the drive chain.

The frequency conversion permanent magnet synchronous motor equipped by VDS adopts the third-generation strong magnetic NdFeB permanent magnet excitation, which has the advantages of small starting current, high power density, high power factor and high conversion efficiency (commonly known as: one small three high ) span> and other outstanding advantages. The load rate is in the range of 25%-120%, and the motor efficiency is always maintained above 90%.

While greatly improving the operating efficiency of the fan system, VDS reduces vibration and noise, and achieves "oil removal - pollution-free " operation. It is an environment-friendly, quasi-maintenance-free drive system.
