Product Display
Introduction to Core Technologies
The product adopts a dual-cavity physical isolation design between the junction box and the motor cavity to block hot gas flow circulation and prevent condensate accumulation in the junction box. It uses low-hygroscopic specialty oil and a dynamic breather valve, achieving dual protection through liquid water isolation and directional moisture expulsion.
Segmented magnet design reduces eddy current losses by 60%
An industry-unique RC (Resistor-Capacitor) board solution reduces shaft voltage and current by 85%, effectively preventing bearing damage.
