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.

Qinshang Optoelectronics was awarded a claim for violation of the law
After being punished by the Guangdong Securities Regulatory Bureau for the violation of the letter, Qinshang Optoelectronics attracted a large number of investor litigation claims, and the accumulated claim amount exceeded 10 million. The reporter learned from the investor's lawyers' office on the 12th that the court had made a first-instance judgment on some cases, and almost all of the investor's claims were supported. After being punished by the Guangdong Securities Regulatory Bureau for the violation of the letter, Qinshang Optoelectronics attracted a large number of investor litigation claims, and the accumulated claim amount exceeded 10 million. The reporter learned from the investor's lawyers' office on the 12th that the court had made a first-instance judgment on some cases, and almost all of the investor's claims were supported. The judgement obtained by the reporter showed that the Guangzhou Intermediate People's Court held that because the Guangdong Securities Regulatory Bureau of the China Securities Regulatory Commission imposed an administrative penalty on Dongguan Qinshang Optoelectronics Co., Ltd. and determined that its conduct constituted a false statement, it should be within the time limit prescribed by the law of the plaintiff investor. The loss of investment in securities transactions and the commission, stamp duty, and interest on the funds involved shall be liable for compensation. Therefore, the court ruled that Qinshang Optoelectronics compensated the plaintiff investors for a total of 600,900 yuan, and assumed most of the case acceptance fees. It is understood that a total of 58 investors filed lawsuits against Qin Shang Optoelectronics in the Guangzhou Intermediate People's Court. The above judgment involved 12 investors. The judgments of the remaining cases are still unclear, but some legal persons said that the remaining investors are more likely to win the case. . The incident originated from Qin Shang Optoelectronics and was twice punished by the Guangdong Securities Regulatory Bureau twice in 2014 and 2015. According to the "Administrative Punishment Decision" of the Securities Regulatory Bureau, Qinshang Optoelectronics has not disclosed the related party transactions between 2008 and 2011, the transaction situation of the second largest customer in 2009 and the largest in 2013 and 2014. Non-operating capital transactions between the shareholders of Dongguan Qinshang Group Co., Ltd. of 1.827 billion yuan. Qin Shangguang’s two violations were fined 400,000 yuan and 500,000 yuan by the Guangdong Securities Regulatory Bureau. After the disclosure of the situation, litigation claims from investors also followed. On November 4, 2016, Qinshang Optoelectronics responded to the Shenzhen Stock Exchange's inquiry letter, claiming that a total of 58 investors filed a lawsuit with the Guangzhou Intermediate People's Court, demanding that the company bear civil liability for information disclosure violations. The 58 investors mentioned above claimed a total of RMB 13.404 million, of which 23 investors involved (the amount involved: RMB 4,180,600) was heard on August 2, 2016; 15 investors involved The piece (the amount involved: 6,340,500 yuan) was heard on October 28, 2016. One of the plaintiffs’ investor lawyers, Xie Liang, a lawyer from Guangdong Huanyu Jingmao Law Firm, revealed that he arrived at the Guangzhou Intermediate People’s Court on the afternoon of the 12th to receive the judgment of the case on October 28 this year. Only one and a half months after the trial, the court made The first-instance judgment made him a bit surprised. Xie Liang also said that some cases have also received a second-instance ruling on jurisdictional objections in the near future, and it is expected that the trial will soon be held. In addition, the claim for the second penalty in the case is approaching the statute of limitations, and eligible investors can sue before March 18, 2017 at the latest. The Qinshang Optoelectronics Claims Case is another investor's collective claim case after the Guangzhou Intermediate People's Court has tried the Foshan Lighting Claims case. Different from the Foshan lighting case, the Shenzhen Composite Index was stable in the claim area of ​​the Qinshang Optoelectronics Claims Case, and the court did not deduct systemic risks. Therefore, almost all of the investor's claims have received full support. Some of them do not receive 100% support, mainly because there is a certain error in the calculation. He said. Xie Liang said that according to the "Securities Law" and "Several Provisions of the Supreme People's Court on the Trial of Civil Compensation Cases Caused by False Statements in the Securities Market" and the judgment of the first instance of the court, the claim for the second punishment within the scope of the statute of limitations is currently The conditions are: buy before January 2, 2013 to December 2, 2014 and sell or still hold the damage of Qinshang Optoelectronics stocks after December 2, 2014 to the base date, January 9, 2015. Investors can claim loss of investment balance, commission, stamp duty and interest. In the case of Foshan Lighting Securities misrepresentation disputes reported, more than 2,700 investors received nearly 200 million yuan in compensation, setting a new high in the securities market in recent years.
