For the design of electrical machines the magnetic circuit has to be modeled. If only the winding layout or the stack length of the motor is changed a complete FEA analysis mostly is not necessary. In this case Modelica is well suited to model the magnetic circuit for quasi-stationary simulations. A new library based on existing standard libraries MagneticQS is presented. An induction motor example under no-load conditions shows the basic concept of this library. To enhance and improve the library new models for different types of machines and the possibility of an integral simulation independent from the load conditions is planned.
