Mounting Base:With Mounting Base Shaft Material:Stainless Steel is_customized:Yes Model Number:M2 Type:Wind Power Generator Origin:Mainland China Certification:CE Generator Type:The permanent magnet generator The material:Stainless steel The characteristics of:Run small vibration The warranty:1 year Life:More than 20 years The permanent magnet generator has the following advantages: 1, simple structure, high reliability Get rid of the permanent magnet generator exciting winding, brush, collector ring structure, so the whole machine structure is simple, avoids the excitation generator exciting winding burned, break easily, brush, collector ring is easy to wear, such as fault, with reliable performance. 2, small volume, bigger than power Rotor permanent magnet generator using a simplified structure, a parallel structure and series magnetic structure of two kinds: parallel magnetic field of the structure of the rotor made of casting, permanent magnet embedded in it, high rotation speed. Series field structure of the rotor adopts steel structure, permanent magnet embedded in the surface, the surface of the rotor magnetic induction intensity is strong, the overall structure is firm and reliable. Because the rotor structure simplification, the generator's internal structure is compact, the rotor moment of inertia of small, practical speed increase, therefore, improves the power (power and the ratio of volume). 3, power at low speed performance is good Permanent magnet generator power at low speed performance is good, high output power. In idle running, the permanent magnet generator power output is twice as tall as excitation generator output power to. 4, high efficiency and energy saving General excitation generator in the 1500-6000 r/min speed range between the average efficiency is only about 50%; While the average for the permanent magnet generator efficiency can reach 75% ~ 80%. Therefore, the permanent magnet generator is more energy-efficient. Conversion efficiency is higher 5, high precision voltage regulator, can prolong the service life of battery Permanent magnet generator adopts switch rectifier regulator method, using small current pulse charging, avoid the over current charging and the possibility of damages to the battery, can prolong the service life of battery. 6, no radio interference Brushless permanent magnet generator, collector ring, in the operation of the electric spark generated, therefore, no radio interference, greatly improving the use performance.
