Low speed permanent magnet direct-drive generator. Do not need the gearbox. The turbine connects with the PMG directly, simplifying the structure and improving the system performance.
The gearbox reliability is not high. The system reliability can be improved if there is no gearbox. That means less maintenance, better utilization, longer lifespan for the system.
The efficiency is high. The system efficiency can be improved by 20% when you use PM generator without gearbox.
The PMG can work efficiently throughout the whole speed range. Less heat when working. The PMG can use natural air cooling.
Low start up torque, the system can output power at low speed.
The PMG works at low speed, low noise, more safe and reliable, the lifespan of the bearings can be longer.
The voltage, speed ,power of the generator can be customized. The shape can also be changed, using spine shaft, dual shaft, front edge or other output ways.
