Motor-CAD is a commercially available thermal analysis software that uses a 3D lumped parameter circuit model. It is capable of modelling steady-state, simple transient, and duty-cycle transient thermal characteristics. Interior rotor SRMs are a standard motor type available with a pre-generated thermal network in Motor-CAD. The user is required to input geometric parameters in order to approximate the temperature variation in an SRM. The axial and radial cross section views of an SRM in Motor-CAD can be seen in Figure 14.21. Figure 14.22 shows the thermal network layout for an SRM in Motor-CAD. In the network, each node, which represents a specific spatial position in a motor’s geometry, is connected to other nodes using a calculated thermal resistance value. Motor dimensions and material properties are used to calculate the thermal resistance.

Motor-CAD FEA was utilized for investigating the effects of design parameters on the performance of the electrical machine. The design variables such as the geometric sizing, materials, and cooling types were the key elements that needed to be considered during the design process. The 2D-FEA dealt with the electromagnetic circuit of the machine over a full operational speed range. The electromagnetic and heat transfer parameters were then automatically calculated by defining the control options and materials.
