What is the generator belt model for Wuling Rongguang?

[VonBrianna]

The generator belt model for Wuling Rongguang B12 engine is 4PK850. PK refers to the tooth pitch = 3.5mm, while 4 indicates the belt has 4 wedge teeth, and 850 represents the effective length of the belt as 850mm. The engine principle is introduced as follows: 1. Introduction one: The operational resistance of a car generator is related to the excitation voltage and current of the rotor. The greater the excitation current, the larger the power generation, and correspondingly, the greater the operational resistance of the generator. For common AC or DC generators, when there is no output current, the coil is equivalent to an iron lump with bearings. 2. Introduction two: Apart from bearing friction, there is no other resistance. When the output end is connected to a load, the rotor will generate a strong magnetic field that interacts with the stator coil magnetic poles, creating attraction. The stronger the magnetic field, the greater the operational resistance. The heavier the load, the greater the resistance to magnetic field line cutting, meaning the operational resistance increases.
