The new electric servo cylinder manufacturers focus 10 annual. Electric servo-cylinder is a linear actuator to achieve precise control, it is primarily the servo motor and lead screw integrated modular design, the rotary motion of the servo motor is converted into linear motion, while the servomotor best advantage - precise speed control, precise rotation speed control, precise position control, precise pressure control; precise torque control into - the precise speed control, high precision linear motion a new revolutionary product. Electric servo cylinders of different forms of control servo-electric cylinder motion analysis in the field of industrial automation and control plays a very important role. With different applications, servo electric cylinder control performance requirements are also different. Thus, in practice, there are various electric servo-cylinder control forms. From the control volume, these forms of control are: speed control; torque control / current control; position control. 1. Speed ??control in the speed control form, asking to control the speed of the electric servo-cylinder under various operating conditions, in order to meet the work requirements of the load, which is a very wide range of applications in the form of a control. Electromagnetic torque generated by the electric servo-cylinder only larger than the load torque, in order to make electric cylinder and its load to achieve accelerated. In Tf = 0, the difference between the electromagnetic torque and load torque of the electric cylinder, namely dynamic acceleration torque. 2. Torque control / current control some loads, such as bolt tightening mechanism, you only need to provide the necessary electric servo cylinder clamping force, and according to the size of the required tightening force to determine the electric servo-cylinder torque control closed and torque limit, and speed and position servo electric cylinder is no requirement. In this application, it should be used in the form of torque control. Also, because the servo system, the electric cylinder strong permanent magnet rotor pole position measured by the position sensor, and this signal as the basis for the current control in order to achieve and two orthogonal field current control. In this case, the electromagnetic torque and the armature current is proportional to the electric servo-cylinder generated, it is, in fact, the torque control current control. 3. The position control servo electric cylinder position control system, from the positioning requirements of view, the best position sensor mounted directly on the machine to be positioned to achieve the so-called closed-loop control. But in fact, can be dragged on a mechanical or too little with the drag on relative movement of the mechanical machinery directly mounted sensor, which is due to ease of installation, but also particularly concerned mechanically dragged vibration and deformation of the adverse effect on the position control system. Based on the above, the general practice in the use of semi-closed loop control mode, the position sensor is mounted on a shaft electric servo-cylinder non-load side. By measuring the electric servo-cylinder axis angle, to indirectly measure the actual displacement of the mechanical drag, enabling the position servo control. At present, the application of the more general position sensor with all kinds of encoders, resolvers. Take control in the form of electric servo cylinder, can also help us to understand the principles and use of screw jacks or the like.
