Materials

Materials used in the problem and are defined through the Solid Material window. The first required step is the creation of the magnetic potential variable. In order to do it, open the Solid Material window and select the URSOLVER page of any of the existing materials. Then insert the name Potential in the Variable Name field and press Enter[6].

Rotor

Based on one of the existent solid materials, create a new one called Rotor. The URSOLVER properties of this material have to be fixed as given below (see Figure 136). Only properties in the URSOLVER page have to be changed[7].

f3 0.0

f4 0.0

Rotor material has to be assigned to the inner surface of the model as shown in Figure 137.

Stator

Based on one of the existent solid materials, create a new one called Stator and define the same properties as in the previous case. This material has to be assigned to the external surface of the model as shown in Figure 137.

Coil

Based on one of the existent solid materials, create a new one called Coil. The URSOLVER properties of this material have to be fixed as given below and the material has to be assigned as shown in Figure 137.
