Advantages Of Permanent Magnet Generators
1: Simple structure and high reliability. The permanent magnet generator eliminates the excitation winding, carbon brush and slip ring structure of the excitation generator. The structure of the whole machine is simple, and the excitation winding is easy to burn and break, the carbon brush and the slip ring structure are simple, and the whole structure is simple. The excitation of the excitation generator of the excitation generator is easy to burn, the wire is broken, the carbon brush and the slip ring are easy to wear, and the reliability is greatly improved.
2: Small size, light weight and high specific power. The adoption of the permanent magnet rotor structure makes the internal structure design of the generator very compact, and the volume and weight are greatly reduced. The simplification of the permanent magnet rotor structure also reduces the rotor moment of inertia, the practical speed increases, and the specific power (ie, the ratio of power to volume) reaches a very high value.
3: Medium and low speed power generation performance is good. In the case of the same power level, the permanent magnet generator is twice as high as the output power of the excitaResonator tion generator at idle speed, that is, the excitation generator of the actual equal power level of the permanent magnet generator.
4: Can significantly extend battery life and reduce battery maintenance. The main reason is that the permanent magnet generator adopts a switching type rectification and voltage regulation mode, which has high voltage regulation precision and good charging effect. Avoid shortened battery life caused by over current charging. The initial rectified output of the permanent magnet generator uses a small current pulse to charge the battery, and the same charging current has better charging effect, thereby prolonging the service life of the battery.
5: High efficiency. Permanent magnet generators are an energy-saving product. The permanent magnet rotor structure eliminates the excitation power required to generate the rotor magnetic field and the mechanical loss of friction between the carbon brush and the slip ring, so that the efficiency of the permanent magnet generator is greatly improved. Ordinary excitation generators have an average efficiency of only 45% to 55% in the range of speeds between 1500 rpm and 6000 rpm, while permanent magnet generators can be as high as 75% to 80%.
6: No self-energizing power supply is required for the self-starting regulator. The generator can generate electricity as soon as it is rotated. When the battery is damaged, the car charging system can still work normally as long as the engine is running. If the car does not have a battery, as long as the handle is turned or the car is turned, the ignition operation can also be realized.
7: It is especially suitable for working in harsh environments with high humidity or dust.
8: Radio interference. The permanent magnet generator has no carbon brush and no slip ring structure, which eliminates the radio interference caused by the friction between the carboMachine Hardware n brush and the slip ring; eliminates the electric spark, and is especially suitable for working in an environment with a high degree of explosive danger, and also reduces the generator. Environmental temperature requirements.PMG VS Generator
Permanent magnet generator: simple structure, large rotor magnetic field, no excitation winding, no carbon brush, no slip ring, large air gap, no contact, the only wear part of the whole machine is the bearing. The product reliability is improved, no external regulator is used, and the spacing of the magnetic material of the magnet is optimized, the magnetic flux leakage is reduced, the idle speed performance of the generator is good, and the circuit is sufficient.
Exciting generator: The performance of idle power generation is poor, the battery is easy to discharge; the generator speed is only 40%-50% between 1500-6000 rpm and the efficiency is low. Because the rotor has excitation coil, the whole machine temperature rises. Excitation generators are also prone to problems such as carbon brushes and slip ring damage.
