introduction：The main reasons for Siemens servo motor heating are: 1、overcurrent。Run with load due to prolonged exceeding rated current，The driver overcurrent protection value is set to exceed the rated value but lower than the current actual operating value and the driver does not alarm，Or disable overcurrent protection，The practical solution may be to find whether the motor bearing is normal，Whether the terminal of the three-phase power supply of the motor is securely connected，Whether the three-phase current is unbalanced，Whether the rotation direction of the motor changes too fast！

introduction：The principle of photoelectric speed sensor is shown in the figure，It consists mainly of light sources、condenser、Reflective transparent glass、Photosensitive tube and other components。The light beam produced by the light source is reflected through the transparent glass Onto the optical code disk，The optical code tray is installed on the rotating shaft of the measured speed。There are some on the surface of the optical code disk Radiant and spaced reflective surfaces and non-reflective fringes。So when the shaft rotates，The optical code disc emits an interval of reflected light onto a photodiode，Make the resistance value of the photodiode produce alternating changes。

introduction：How to wire solid state relays A solid state relay is an electromagnetic switch，Use a small current to control a large current，Be a headlamp，Oil pump when these switches are on，The contact point of the switch on the instrument table cannot withstand a large current，Otherwise itll burn.，A relay sends a large current to the electrical equipment，Its like a valve in a water pipe，Small control current，It turns on the solenoid in the relay，A magnetic field is generated when the coil is energized，Suck the metal out of the relay，flapping，It drives a lot of current through the contacts，The contact is connected to power。To achieve the purpose of controlling high current。I believe many people want to know how to wire solid state relays, right，The following Xiaobian will use a picture to tell you。

introduction：Now the best performance of the AC motor governor is the frequency conversion governorthe，It is by changing the motor power frequency to achieve speed regulation，Wide speed range，Energy conservation，It can slow down or speed up，And can be used as a motor starter，But the price is relatively high。The other is called a magnetic transmission，The cost performance is similar to the frequency converter，But the principle is different.，It is characterized by long life、Low maintenance，At present, it has been used in large motor speed regulation。Simple AC motor governor can use current limiting、Ways to reduce blood pressure，Like a governor on a fan，This method of speed regulation is simple，But the load characteristics of the motor are very poor，Only suitable for small motor and stable load occasions。

introduction：In recent ten years, it has been widely used in oilfield pumping units，It is a small and medium tin-iron boron permanent magnet synchronous motorApplication of more successful examples。This type of permanent magnet motor is usually provided with a starting winding on the rotor，The ability to start directly at a certain frequency and voltage，Therefore, it is called asynchronous start permanent magnet synchronous motor。towards100kw~1000kWFor the high-power synchronous motor，The asynchronous starting permanent magnet synchronous motor eliminates the excitation cabinet，The contrast electric excitation synchronous motor not only improves the efficiency、Simplified structure，And it doesnt cost much more，Therefore, it has become another important application，In order to8very110kwTake permanent magnet motor as an example，Its efficiency reaches95%，The power factor is0.916，The amount of permanent magnet is0.15kg/kW。
