TaiwanABBALead screw,ABBALead screw advantage,ABBAScrew characteristics,ABBABall screws are available through a selection of spacers of various thicknesses,The preload on both nuts can be finely adjusted,High rigidity can be obtained easily by selecting appropriate prepressure。In addition,Select a single nut to achieve no backlash(Light precompression)The state of。
The development of speed sensorless control technology begins with the conventional transmission control system with speed sensor,The starting point to solve the problem is to use the measured stator voltage、The speed sensor is replaced by the speed estimation of easily detected physical quantities such as current。Today, Xiaobian will introduce you to the control method without speed sensor!
Panasonic servo motor has a simple structure,Reliable operation,Easy to use,Low price and other features。In order to ensure the normal operation of the time, the motor should be checked according to the requirements of the motor sound quality standard,The running motor should be aligned with the axis of the device being dragged,There is no obvious vibration in operation,Be sure to keep the air well ventilated、The wings need to be intact。Always observe and measure the voltage and normal working current of the motor network,The voltage change should not exceed the rated voltage±5%,The rated load current of the motor should not always exceed the rated current,In case of overheating,At the same time, check whether the motor starting protection device is flexible and reliable。
People take classical electromagnetism as the theoretical basis,Displacements that do not facilitate quantitative detection and processing、position、Liquid level、dimension、Flow rate、speed、Physical quantities such as vibration are converted for easy quantitative detection、The amount of electricity that facilitates the transmission and processing of information。This is the displacement sensor that is widely used in production and life。
Double row deep groove ball bearings are suitable for applications in a bearing configuration where the load capacity of a single row deep groove ball bearing is insufficient。For double row deep groove ball bearings with the same outer diameter and inner diameter as deep groove ball bearings,Its width is larger,The load capacity is also much higher62and63Series of single row deep groove ball bearings。
Solenoid valve principle Solenoid valves are industrial equipment controlled by electromagnetism,It is a basic element of automation used to control fluids,actuator,Not limited to hydraulics、pneumatic。Used in industrial control systems to adjust the direction of media、Flow rate、Speed and other parameters。The solenoid valve can be combined with different circuits to achieve the desired control,The accuracy and flexibility of the control can be guaranteed。
Baldor solenoid valve Baode solenoid valve is an industrial equipment controlled by electromagnetism,It is a basic element of automation used to control fluids,actuator,Not limited to hydraulics、pneumatic。Used in industrial control systems to adjust the direction of media、Flow rate、Speed and other parameters。 Baode solenoid valve main features:
Current relay connection relay(English name:relay)It is an electrical control device,Is when the input quantity(Excitation quantity)When the changes meet the specified requirements,An appliance that causes a predetermined step change in a controlled quantity in an electrical output circuit。It has a control system(Also known as input loop)And the controlled system(Also known as output loop)The interaction between。It is usually used in automatic control circuits,It actually uses a small current to control the operation of a large current“Automatic switch”。The following Xiaobian will take you to understand the current relay connection diagram。
Pointer type current relay The pointer type current relay performs automatic regulation in the circuit、Security protection、Conversion circuit, etc。It is usually used in automatic control circuits,It actually uses a smaller current to control a larger current“Automatic switch”。
