Mathematical modelling and numerical simulation of linear electro-hydraulic servomechanism with stepper motor

Dynamic Modelling and Simulation of a Hydraulic Stepper Cylinder Used in Manipulators and Robots

The present paper describes dynamic modelling, results of simulation and experimental investigation of a hydraulic stepper cylinder, which find application in manipulators and robots. The method of bond graph is used for modelling of the dynamics of the considered cylinder design. First, an initial digital simulation is performed in order to calculate basic dynamic characteristics of the cylind...

Stepper Motor Model for Dynamic Simulation

The modeling and simulation of the electromechanical behaviour of stepper motors are of high interest because they are often used for space application. A commercially available multibody dynamic simulation software, which sets up the equations of motion and the transfer function of the motor and solves them numerically, was used. The results show, that both the dynamic simulation software and ...

Mathematical Modelling of a Hydraulic Accumulator for Hydraulic Hybrid Drives

Dynamic Simulation of a Novel Hybrid Linear Stepper Motor by Means of Matlab/simulink®

The main advantage of linear motors is that they do not turn the electric energy supplied into a rotary movement, but convert it directly to a linear movement. The direct coupling of the mover armature to the load provides several performance benefits in addition, as high speeds, high precision, no backlash, high stiffness and fast response and settling times. In these circumstances it is inter...
