Caspoc for electrical drives simulations

Caspoc is also the simulation package for electrical drives, because you can combine the electrical machine, the mechanical load, the power converter and the control one schematic.

Special attention is given to the build-in machine models, which are optimized for simulation speed.
You either connect an electrical machine to a grid, or to an inverter.
The input for the electrical machine is always electrical. The output from the electrical machine is always the torque produced by the machine. You have to connect a model for a mechanical load to the output of the machine. The output from such a load model gives the angular speed.

If you want, for example, to make a model of an induction machine, connected to a grid, you select:
  1. A three-phase grid from the library
  2. An induction machine from the library
  3. A load from the library
The output from the load-block is the angualr speed and the torque applied to the load. You can connect a SCOPE to the output of the load to see the torque/speed curve.
