Is the story of Li Hongtao brushless motor true or not?

This story is true. However, it was Li Hongtao, not Li Hongtao, who invented the brushless electric excitation motor, not the brushless motor. Li Hongtao announced his invention in prison under the pseudonym of Yang Hongjun.

At the invitation of his classmates, Li Hongtao started a company, but due to lack of funds, Li Hongtao forged the bank seal of another company and successfully transferred 80,000 yuan. However, when preparing for the second transfer, he and his classmates were arrested by the police.

Li Hongtao escaped from prison twice. 199265438+On February 8th, Li Hongtao was arrested by the police for the third time.

1February, 993, Li Hongtao was escorted back to Kunming, the original crime scene, and was put into the No.1 detention center in Kunming. At this time, Li Hongtao was thinking about being sentenced, and on the other hand, he was thinking about the idea of "brushless motor".

1993 12. the Supreme People's Court approved Li Hongtao's death penalty and issued a notice of execution to Kunming Intermediate People's Court.

According to the regulations, the death penalty must be executed within seven days after the sentence is pronounced.

Life began to count down, and Li Hongtao began to race against time.

At this time, although Li Hongtao made great progress in his experiment, he encountered an unsolvable problem.

Until several experts invited by the detention center arrived. Experts gave on-site guidance to Li Hongtao and told him the most advanced theoretical knowledge at home and abroad at that time.

If Li Hongtao is enlightened, he suddenly realizes the crux of the problem.

1993 The last day of June is the deadline for Li Hongtao's life. If the experiment is still unsuccessful, he will be executed as scheduled.

Everyone has no hope for this. In the experiment that day, several people, including Li Hongtao, just stayed in the room of the big workshop.

But Li Hongtao is really confident at this time.

The circuit has been built, just waiting for electricity.

Turn on the power switch, it is a flash of lightning, and the motor suddenly turns.

The cells immediately boiled up. Several leaders rushed over together.

On the night when the experiment was successful, director Sun Eryun hastily wrote a report, demanding that Li Hongtao's execution be suspended. The director of Kunming Public Security Bureau personally instructed this suspension request.

Extended data:

1March 995 10, Yunnan higher people's court commuted Li Hongtao's death sentence with a two-year suspension. This year, Li Hongtao's "Brushless Motor Magneto" won the gold medal and the first prize of excellent invention in the 5th China Patent Invention Expo.

In the following years, Li Hongtao made many inventions and obtained three invention patents and three utility model patents.

In view of Li Hongtao's great meritorious service, the death penalty was commuted to fixed-term imprisonment on Christmas Day according to law 1997. On July 25, 2000, the sentence was reduced by two years. On July, 2002, the sentence was reduced by one and a half years.
