The horizontal supporting funds for auto parts are established by the state for the special support and support of the development of auto parts and national industries. The National Development and Reform Commission arranges and entrusts financial institutions to make loans. The loan period is 3 to 5 years and the annual interest rate is much lower than that of general bank loans. .
Under the macroscopic background of the current monetary contraction, many auto parts companies in China are actively fighting for this fund. Recently, the application of the national horizontal supporting fund for auto parts reported by Leling City was approved by the National Development and Reform Commission. The city’s Jin Qilin Group received a special low-interest loan of 50 million yuan and became the first and only company in Dezhou to obtain this support. At present, the funds are in place.
Working principle of integral Alternator
When the external circuit through the brush excitation winding is energized, it generates a magnetic field, the claw pole magnetized N pole and S pole. When the rotor rotates, flux alternately in the stator windings changes, according to the electromagnetic induction principle knowable, the stator three-phase winding produced alternating induced electromotive force. This is the alternator power generation principle.
The original motivation (i.e. engine driven DC excitation of synchronous generator rotor, with the speed of n (RPM) rotation, three-phase stator winding induction AC voltage. The stator winding if access to electricity load, motor with AC power output, after internal generator rectifier bridge will convert AC to DC power is output from the output terminal.
The content of AC generator stator winding and rotor winding and the three-phase stator winding according to the mutual difference distribution of 120 electrical degrees on the shell PTT and rotor winding is composed of two pieces of claw pole. When the rotor windings connect when DC is two pole excitation, the formation of N and S poles. Magnetic pole starting from N, through the air gap into the stator core to the adjacent S. Rotor once rotated, the rotor winding will cuts the magnetic lines of force and mutual difference of 120 electrical degrees of sinusoidal EMF in stator windings, the three-phase alternating current, again through the diode rectifier changed to DC output.
When the switch is closed, the current is supplied first by the battery. Circuit:
The positive battery, charging indicator, regulator, excitation winding, contact ground, negative battery. At this time, due to the current through the charging indicator light, so the exhibit of lanterns.
But after starting the engine, with the increasing speed of the generator, the terminal voltage of the generator is increasing. When the generator output voltage and the battery voltage is equal to the generator "B" and "d" end of equal potential. At the same time, the charging indicator due to the ends of the potential difference is zero and extinguished. The generator has been instructed to work properly, the excitation current is supplied by the generator itself.Generator three-phase winding three-phase AC electromotive force generated by the resistance after diode rectifier, DC output, power supply to the load and to the battery charging.
