Tesla biography Reading

Chapter III High-income immigrants Tesla in the meager incomes, hard living conditions still work hard to do the work of the creation of AC motor, in the life of the poor, their inventions are not known to the situation Tesla can still persist, in his own creation of the great spiritual happiness, This requires not only a scientific researcher rich imagination, bold innovation ability, a solid knowledge of the reserves, but also the need for their own cause of unlimited interest and passion, in the face of setbacks and difficulties without retreat of courage. When his invention was resisted and resented by the same era inventor Edison, Tesla still did not abandon himself to apply the AC system to the production life, spread to the world's great dream, in the poor, after the ordeal he resolutely went to the United States to find opportunities to face the challenge, it is Tesla this indomitable, The character of the hard-to-face created his ultimate success.

and the fifth chapter of the current War of reading, Tesla thick thin hair, after the honed his AC motor and transformer system finally ushered in a new life, has been recognized by the society, and the phase Tesla invented the creation of the Westin House undoubtedly played the role of Bole. Maxima often and bole not often, Tesla is lucky, but this is also a lucky he is in the face of difficulties, perseverance in the pursuit of the dream inevitably happen. But Tesla's AC system has been constantly impacted and vilified by industry leaders and other experts in the DC system since its inception, and Edison has even made a nationwide rumor propaganda about the dangers of alternating electricity, and in the face of this series of slurs and attacks, Tesla and Westin House did not care too much, not to flinch, They resisted this series of shocks, focused on meeting the challenges of the future, eventually won the Battle of electricity, so that the world accepted the exchange of electricity safe and reliable facts. In the face of GE's price war offensive, Tesla showed superhuman generosity and atmosphere, he indifferent to fame and fortune, gave up the opportunity to become a millionaire, to save his friends, save his inventions to the homes of Westinghouse Electric Company and abandoned the unprecedented amount of patent tax, but focused on the invention research , together with Westin House to let AC power to the country. It is precisely because Tesla indifferent to fame and wealth, the attitude of focusing on scientific research so that he in a round of slander and slander in the outside, still focus on research, to achieve the world's attention to achievements.

The fourth chapter of three-phase asynchronous motor is easy to understand, the focus is on the three-phase current generation of magnetic field synthesis and changes in the magnetic field due to the change of understanding, and the induction motor slip understanding is particularly critical. The understanding and calculation of the two connection modes and the rated parameters of the rated parameters of the asynchronous motor are simple, and the energy flow diagram needs to deepen the understanding of the copper loss and the iron loss of the stator rotor. The derivation of the formula for calculating the effective value of the induction electromotive force in the stator circuit and the rotor circuit of the three-phase asynchronous motor and the understanding of the vector formula require special attention, while the influence of slip on rotor EMF, rotor inductance, rotor circuit power factor understanding, three-phase induction motor torque calculation is more difficult. The mechanical characteristics of three-phase asynchronous motor is more difficult, hope the teacher can explain in detail.
