Description

Block Translational Electromechanical Converter provides an interface between electrical and mechanical (translational) domains. It converts electrical energy into mechanical energy in the form of translational motion and vice versa. The converter is described by the following equations:



where

  • — voltage at the electrical ports of the converter, In;

  • — current through the electrical ports of the converter, and;

  • — power, N;

  • — speed, m/s;

  • — proportionality coefficient.

Block Translational Electromechanical Converter It represents a lossless electromechanical energy conversion, so the same coefficient is used in both equations.

The + and − connections are electrical ports corresponding to the positive and negative terminals of the converter. The C and R connections retain mechanical translational ports. If the current flowing from the positive to the negative terminal is positive, then the resulting force is positive and acts from port C to port R. This direction can be reversed by using a negative value for K.
