Description

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



where

  • — voltage at the electrical ports of the converter;

  • — current through the electrical ports of the converter;

  • — power;

  • — speed;

  • — proportionality coefficient.

Block Rotational 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 represent mechanical rotary ports. If the current flowing from the positive terminal to the negative terminal is positive, then the resulting torque is positive and acts from port C to port R. This direction can be changed by using a negative value for .
