Rotational Electromechanical Converter
The interface between the electrical and mechanical (rotational) domains.
Description
The Rotational Electromechanical Converter unit provides the 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:
-
- is the voltage at the electrical ports of the inverter;
-
- current through the electrical ports of the inverter;
-
- power;
-
- speed;
-
- coefficient of proportionality.
The Rotational Electromechanical Converter block represents lossless electromechanical energy conversion, so the same coefficient is used in both equations.
The + and - connections represent the electrical ports corresponding to the positive and negative terminals of the converter, respectively. Connections C and R represent mechanical rotary ports. If the current flowing from the positive terminal to the negative terminal is positive, the resulting torque is positive, acting from port C to port R. This direction can be reversed by using a negative value for .
