Translational Electromechanical Converter

Interface between electrical and mechanical translational domains


Electrical Elements


The Translational Electromechanical Converter block provides an interface between the 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 with the following equations:




VVoltage across the electrical ports of the converter
ICurrent through the electrical ports of the converter
KConstant of proportionality

The Translational Electromechanical Converter block represents a lossless electromechanical energy conversion, therefore the same constant of proportionality is used in both equations.

Connections + and – are conserving electrical ports corresponding to the positive and negative terminals of the converter, respectively. Connections C and R are conserving mechanical translational ports. If the current flowing from the positive to the negative terminal is positive, then the resulting force is positive acting from port C to port R. This direction can be altered by using a negative value for K.


Use the Variables tab in the block dialog box (or the Variables section in the block Property Inspector) to set the priority and initial target values for the block variables prior to simulation. For more information, see Set Priority and Initial Target for Block Variables.


Constant of proportionality K

Constant of proportionality for electromechanical conversions. The default value is 0.1 V/(m/s).


The block has the following ports:


Electrical conserving port associated with the converter positive terminal.


Electrical conserving port associated with the converter negative terminal.


Mechanical translational conserving port.


Mechanical translational conserving port.
