introduction：Safety relay brand A safety relay is a combination of several relays and circuits，In order to complement each others abnormal defects，Complete function of relay with correct and low error operation，The lower the error and failure value，The higher the safety factor，Therefore, it is necessary to design a variety of safety relays to protect different grades of machinery，The main objective is to protect machine operators who are exposed to different levels of risk。There are many brands of safety relays but they all work on the same principle，The only difference is the material and the manufacturing process。

introduction：contrinexSensor working principle contrinexA sensor is a detection device，Can feel the information being measured，And can feel the information，According to certain rules to transform into electrical signals or other desired form of information output，To satisfy the transmission of information、handle、store、reveal、Recording and control requirements。With the accelerated development of science and technology，Sensors are also being used more widely。I believe that many people do not understand the working principle of sensors，The following Feng Ye Xiaobian will take you to understand his working principle。

introduction：smcRodless cylinder Rodless cylinder refers to the use of pistons directly or indirectly connected to the external actuator，And make it follow the piston to achieve reciprocating movement of the cylinder。The big advantage of this type of cylinder is that it saves installation space，Divided into magnetic couple rodless cylinder（Magnetic cylinder）With mechanical rodless cylinders。Rodless cylinders are superior to conventional cylinders in many ways，nowSMCRodless cylinders have been widely used，The following Feng Ye Xiaobian will take you to understand his working principle。

introduction：Frequency changer（Variable-frequency Drive，VFD）Is the application of frequency conversion technology and microelectronics technology，The power control equipment of AC motor is controlled by changing the working power frequency of motor。 The frequency converter is mainly commutated（Ac to DC）、filtering、inverse（Dc to AC）、Brake unit、Driving unit、Detection unit, microprocessing unit, etc。Inverter internalIGBTTo adjust the output power supply voltage and frequency，According to the actual needs of the motor to provide its required power supply voltage，Thus achieving energy saving、Purpose of speed regulation，In addition，The inverter also has many protection functions，Like overflow、overvoltage、Overload protection etc.。With the continuous improvement of industrial automation，Frequency converters have also been widely used。

introduction：Wound rotor motorIn principle, it is equivalent to an ordinary asynchronous motor，There are structural differences，So there are distributed windings on the rotor。If the winding on the rotor is shorted at the collector ring，This motor（In usage）Its just an ordinary cage asynchronous motor。 The use of winding asynchronous motors，It is generally in some occasions that require large starting torque，Like a crane（crane）。Its principle is to change the resistance of the rotor winding，To change the slip rate of the asynchronous motor，To change the torque of the motor。Its stator is directly connected to the three-phase AC power supply，The rotor windings are generally connected in series to a variable resistor with a certain resistance value。When the motor starts，The resistance value of the variable resistor is a large value，After the boot is complete，By adjusting the resistance value，Finally, the resistance value is zero。
