Thermal model of solid rotor high-speed induction motor with water cooling
Súkeník, Jakub ; Vítek, Ondřej (referee) ; Toman, Marek (advisor)
This paper deals with thermal calculations of high-speed induction machine with a solid rotor with a copper coating and water cooling. The first part presents the basic equations and mechanisms of heat transfer, and also describes the method of heat network. In~the~next section, thermal resistances for individual parts of the machine and water cooling are derived. The third part describes the distribution of nodes in the heat network of~the induction machine. The last part contains the results of the heat network for~the~high-speed induction machine with the solid rotor with the copper coating and water cooling. Functionality of the created heat network was verified using Ansys software.

Automated Python-Controlled Thermal Analysis of Rotor of Line-Start Permanent Magnet Synchronous Machine
Súkeník, Jakub
This paper deals with the thermal analysis of the rotorof the line-start permanent magnet synchronous machine(LSPMSM). First, a concept of a fully controlled parametricgeometry creation using the Python programming languageis introduced. The geometry is created using the FreeCADsoftware. Afterwards, the geometry is used to perform a thermalanalysis using the finite element method (FEM) in the AnsysWorkbench Software. This analysis is also controlled by Python.A thermal model of the analyzed rotor was also created usinglumped parameter thermal network (LPTN). Finally, the resultingtemperatures from the FEM-based analysis are used to verifythe functionality of the lumped-parameter thermal network.

Thermal Model of Line-Start Permanent Magnet Synchronous Motor
Súkeník, Jakub ; Cipín, Radoslav (referee) ; Toman, Marek (advisor)
This paper deals with the thermal calculations of a line-start synchronous machine. The first part presents the design of line-start synchronous machines. Then the mechanisms and fundamental thermal transfer relationships are proposed, followed by the thermal network method. In the third part, thermal resistances are derived, and thermal models of essential geometrical solids are prepared. In the fourth part, the thermal model of the line-start synchronous machine is described. Then the prepared laboratory model of the line-start synchronous machine is proposed. Next, the measured waveforms of thermal characteristics of the line-start synchronous machine are presented. These waveforms are compared with the calculated waveforms of the transient thermal model of the line-start synchronous machine. Based on the waveforms of the measured temperatures, the input parameters of the transient thermal model of the line-start synchronous machine have been identified. In the last part of the paper, the comparison of the average temperatures of the thermal model with the average temperatures of the finite element thermal models of the line-start synchronous machine created in Ansys Workbench software in a steady state is presented. The creation of parts of the automated parametric geometries is included. Subsequently, the transient finite element thermal model of the line-start synchronous machine is created in Ansys Workbench software. The average temperatures of this transient finite element thermal model are further compared with the average temperatures of the thermal model of the line-start synchronous machine.
