Second week study notes

About the history of the motor, the process I know more or less, the motor of the two categories of generators and electric motors, which from the DC stale exchange of progress, Faraday, Tesla and other people have a rough understanding.

1820 , professor and physicist of the University of Copenhagen, Denmark, found "magnetic effects of electric currents" and established electromagnetic interactions, creating electromagnetics. 1821 , a famous British physicist, made the first model of an experimental electric motor, and after A long period of research and development, the motor has been widely used in industrial production and daily life.

In these advancements, the electromagnetic kinetic energy that is realized by the motor is a tortuous and great process. These advances have made progress in all aspects of today's industry and life.

About the mouth key, I did not read too carefully, can only understand the general, more cognition and experience to wait for further study.

Simulation:

This simulation in the Motor1 principle of adding an inductor, and small amplitude modification voltage, resistance value, the results are as follows:

It can be seen that, with the inductance, the current fluctuates over time, but the value tends to stabilize over time. The motor first reversed, and began to turn at around -3.5, followed by a similar forced vibration of the Crest Trough chart. Because the voltage is reduced in the data modification, the resistor is adjusted so that the current is small and its fluctuation is not obvious. And the initial power-on will cause the circuit current to have a sudden increase in the moment, before it will stabilize.

The rest of the waveforms are pretty well simulated, with little or no access.
