PV70W14-5SW is a semi-enclosed type three-phase self-excited synchronous generator. Its output power is 3KW and it is mainly used in engine driven sets which power level are below 10KW. This type of generator has the characteristics of small size, light weight, reliable performance, simple maintenance etc..

In general, the application field of PV70W14-5SW is mainly used in the areas of automotive, marine, engineering machinery, wind power generation, agricultural and forestry machinery, mobile power station etc. The generator can be used to drive small diesel engines, gasoline engines, diesel generator sets, gasoline generator sets, permanent magnet generators and other engines to get electricity. It also can be used to drive auxiliary machine, pressure machine, drilling machine, grinding machine and other machines which require small power.

The working principle of PV70W14-5SW is based on the interaction between alternating magnetic and electric field. The generator has a stator, a rotor and an armature. The armature is a coil of wire wound on the core of the stator. The core has two opposite polarity. The rotor of the generator has two coils. When the rotor is interacted with magnets, it generates an alternating electromagnetic field which creates a rotating magnetic field in the stator. This rotating field induces a current in the armature.

In order to ensure the normal and reliable operation of the generator, its excitation current control must be accurate, otherwise it will cause the saturation and distortion of the magnetic flux or make the output voltage of the generator out of control. The voltage regulator of PV70W14-5SW is used to adjust the excitation current so that the generator can achieve the optimal performance. The voltage regulator can detect the output voltage status of the generator and output the corresponding feedback signal to the circuit board, then the circuit board will adjust the excitation current according to the signal.

The voltage regulator of PV70W14-5SW also has the functions of over-protection, over-temperature protection, single-phase and three-phase protection, etc. When the motor is over-temperature, the voltage regulator will cut off the output voltage automatically to protect the generator, ensuring the safe operation of the generator.

In conclusion, PV70W14-5SW is a reliable and efficient semi-enclosed type three-phase self-excited synchronous generator. It can be widely used in automotive, marine, engineering machinery, wind power generation, agricultural and forestry machinery and other fields. Its working principle is based on the interaction between alternating magnetic and electric field and equipped with a voltage regulator to control its excit nation current for the optimal performance.
