**Longhong Generator Technology and Performance**  

**Generator Factory Technical Performance**  

The HTW series generators are brushless AC synchronous generators, compliant with relevant national and international standards.  

Machine Features:

1. Steel structure frame.  

2. Standard protection level for all land and marine generators is IP21, with IP22 and IP23 available as optional protection levels. 

    These prevent damage from water droplets entering the machine at angles up to 60° vertically, but the rated power decreases by 5%.  

3. Single-point generators use multi-specification disc couplings, making them easy to connect to various engine flywheels.  

4. Sealed ball bearings are used, eliminating the need for additional lubrication.  

Generator Electrical Characteristics:

1. Insulation class H.  

2. All Foshan generator stator windings are wound with a 2/3 pitch, effectively eliminating the third harmonic of voltage.  

3. Steady voltage regulation rate: ±0.5%.  

4. The excitation stator is equipped with permanent magnets, ensuring the generator does not lose magnetism and can always build voltage.  

**Generator Categories**  

There are many forms of generator principles, but their working principles are based on electromagnetic induction and electromagnetic force laws. 

Therefore, the general principle of their construction is to use appropriate magnetic and conductive materials to form magnetic and 

electrical circuits that interact through electromagnetic induction, generating electromagnetic power and achieving energy conversion.  

Generators in Foshan can be categorized as follows: DC generators, AC generators, synchronous generators, asynchronous generators (rarely used). 

AC generators can also be divided into single-phase generators and three-phase generators.  

**Structure and Working Principle**  

Generators typically consist of a stator, rotor, end covers, brushes, frame, bearings, and other components.  

The stator includes the frame, stator core, winding coils, and other structural parts that secure these components.  

The rotor consists of the rotor core, rotor magnetic poles (including magnetic yokes and pole windings), 

slip rings (also known as copper rings or collector rings), fans, and the rotor shaft.  

The stator and rotor are assembled and connected through bearings, the frame, and end covers, allowing the rotor to rotate within the stator. 

A certain excitation current is introduced through the slip rings, turning the rotor into a rotating magnetic field. 

The stator coils cut the magnetic lines of force, generating induced electromotive force. This is drawn out through terminal connections 

and introduced into the circuit, producing current. Due to the disconnection at the point where the brushes connect to the rotor, 

the rotor rotates in a specific direction, generating alternating current. Therefore, the current in household circuits and similar applications 

is alternating current, commonly known as AC. The frequency of the current output by China's power grid is 50Hz, but generators can also produce 60Hz.
