Creating a DC drive.
The DC Drive is a simple system to model. In the library you will find various electrical machines. From the library we will select a Series DC machine and connect it to a voltage source and a mechanical load. The Series DC machine is selected from components/library/ElectricalMachines/DC
Connect a voltage source, that i1s selected from components/circuit/sources, of 10 volts to the electrical terminals of the DC machine. The mechanical axis of the machine is connected to an inertia that is selected from components/circuit/rotational. A bearing that is selected from components/circuit/rotational is connected to he axis. You can draw the axis just like drawing electrical wires.
The parameters for the electrical machine are default and are
- Ra=0.07
- Rf=0.07
- La=5m
- Lf=5m
- Jm=2m
- K=0.256
- J=1m
- f=10m
The results from the simulation are displayed in the scope. Notice that the current measurement in the voltage source is the current flowing into the voltage source and is therefore negative.
