Product Description

Low Rpm Ac Generator High Efficiency Direct Drive Permanent Magnet Generator

Permanent magnet generator is an electrical machine making the conversion from mechanical energy to electrical energy.
It can offer high efficiency energy conversion, particularly at partial load, and require no separate field excitation system.


Our permanent magnet generators are lighter, more efficient, and require less assembly labor than competing designs.
And used in a large number of applications such as Wind Turbines, Hydro Turbines, motors and others.



GreeF company supply variety of permanent magnet generators which is suitable for driven by following equipments to


1. Driven by Wind Power --------Wind turbine

2. Driven by Water Power ------- Hydro generator

3. Driven by Belt with Motors

4. Driven by Motor

5. Driven by perpetual motion machine

6. Driven by test plant

7. Driven by yourselves creation

8. Driven the permanent magnet generator and make it rotate then it can generate power



Product Advantages
