synchronous or asynchronous avilable speed,voltage, power,frequency could be customized according to user's requriements wind cooling and water cooling type class H insulation , protection grade IP55, started directly, without control cabinet Finite element analysis is used in designing. Compact structure, low startup torque solves the problem of low speed. Inproving water energy utilization strong rotors, the generator could achieve high speed small size, light weight , high energy density, suitable for special situations run efficiently throughout the whole speed range, hight efficient on producing power high-speed oil-contained bearings, maintenace free, more reliablem long service life the parameters like voltage, speed, power can be customized, the shape can be changed, more mounting way for your choice, like spline shaft, biaxial extension, flange CE approved
