Advantage
Our permanent magnet generator adopts advanced permanent magnet materials and optimized electromagnetic design, which is compatible with existing power grid systems, has high control accuracy and response speed, ensures stable power output, improves energy conversion efficiency, maximizes energy utilization, and is less noisy and easier to maintain.
NdFeB Rare Earth Material
• NdFeB has high saturation magnetization, which enables them to resist demagnetization.
• Flux density of NdFeB varies very slowly, so neodymium magnets remain stable for a longer duration. • The magnetic strength of the neodymium magnet is far more than that of ordinary magnets. • NdFeB magnets are usually brittle but can resist chips or crack up to a certain external force limit.
Main characteristics of PM generator
1)Low-speed direct drive, eliminating the speed increaser, the wind blade or hydro turbine can be directly connected with the generator, coaxial rotation, simplifying the structure and improving the system performance. The generator can directly output 50HZ at low speed. 2) Permanent magnet generator in the whole speed range of the motor is efficient operation.high power generation efficiency, the motor heat is small, can rely on natural conditions heat dissipation. 3) High efficiency, small starting torque, can achieve low-speed power generation. The system runs smoothly and the performance is stable. The motor runs at low speed, the power generation is stable, and the service time is doubled. 4) Can change the voltage, speed, power and other parameters according to needs, can change the appearance, can use spline shaft extension, double shaft extension, front end stop output, etc. 5) Small size, light weight, high energy density, suitable for special situations. Adopting imported high-speed oil bearing, maintenance free, and high reliability.
