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
