Main Components
PMSM motor

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. 
Protection level is IP55, passing UL, EMC, LVD, ROHS certificates.

3. DANFOSS (Denmark) VFD


Driving Hub                                                                                                

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.
