introduction：Photoelectric sensor is a sensor using photoelectric element as a detection element。It first converts the measured change into a change in the light signal，The light signal is then further converted into an electrical signal with the help of a photoelectric element。Photoelectric sensors generally consist of light sources、The optical path and the photoelectric element are composed of three parts。 Photoelectric sensorThe various applications are introduced： one、Smoke and dust turbidity monitor： Preventing industrial smoke pollution is one of the important tasks of environmental protection。To eliminate industrial smoke pollution，The first thing to know is soot emissions，Therefore, the smoke source must be monitored、Automatic display and alarm。The turbidity of the smoke in the flue is measured by the variation of the light as it travels through the flue。If the flue turbidity increases，The light emitted by the light source is increased by the absorption and refraction of the soot particles，Less light reaches th

introduction：Synchronous motor，And induction machine（Asynchronous motor）The same is a commonly used AC motor[1] 。Synchronous motor is the heart of power system，It is a set of rotation and rest、Electromagnetic changes are integrated with mechanical motion，A component that converts electrical and mechanical energy，Its dynamic performance is very complex，Moreover, its dynamic performance has great influence on the dynamic performance of the whole power system。The characteristic is：Steady running time，There is a constant relationship between the speed of the rotor and the frequency of the gridn=ns=60f/p，amongfGrid frequency，pIs the number of poles of the motor，nsCalled synchronous speed。If the frequency of the grid is constant，The speed of the synchronous motor in steady state is constant and has nothing to do with the size of the load。Synchronous motor is divided into synchronous generator and synchronous motor。The alternators in modern power plants are mainly synchronous generators。
