Motor System--- PMSM motor technology
1.Low backlash assembly process and gear grinding technique, lower noise
2.Strength the bearing frame structure, increase oil seal and strength the motor structure with trapezoidal shaft structure, higher safety
3.Adopt IE2 high efficient motor, save more 5-10% than IE1
4.Passed CCC, CE, UL certificates
Control Sytem (VFD Controller)
1. SCHNEIDER (France) electrical sets, with safety protection module inside which will interrupt the output automatically in case of some accidents.
2. Germany Rittal control cabinet, passed EMC by SGS and CCC certificates, meanwhile, passed anti-creeping tests which shields electromagnetic interference effectively.
3. DANFOSS (Denmark) VFD
Adapt imported aluminum material and formed through 1500T hot forging+CNC lathe processing+CNC precious machincing technology. Processed by CNC, the precision error of chassis is within 100μm, making sure the precise dynamic balance.
Aircraft grade 7050 hard aluminum material which is handled with heat to guarantee strength and toughness.It stood millions fatigue tests to avoid the problems of fan blade dropping due to long-time running.
Patented Kale Airfoil Blades™ Fan Blade
High strength aircraft grade magnalium, fluorocarbon painting on surface, aerodynamic fan blade design. Patented Fan blade design: 3 sets reinforcing rib supports system inside, enhance the strength of fan blades and avoid sagging of fan tail and fatigue loss of connecting components.
