Fault Tolerant Permanent Magnet Synchronous Motor
Vaško, Dávid ; Mach, Martin (referee) ; Vítek, Ondřej (advisor)
This thesis deals with fault-tolerant machines. The first part covers the theory of faults in electrical machines and the possibility of increasing fault tolerance, especially for PMSM. The second part includes the analytical calculation of the main dimensions of the Dual-Three phase Fault-Tolerant surface mounted permanent magnet machine needed to create a RMxprt model. In the third part, the thesis deals with creating a model in ANSYS RMxprt, Maxwell 2D, and Motor-Cad and comparing the results. In the fourth part, the machine was optimized for the highest possible torque density at the highest efficiency and simplified thermal model was built including oil cooling. The fifth part deals with simulations of fault conditions: open circuit and single-phase short circuit. In the sixth part, a motor with interior permanent magnets was designed and simulated under the same fault conditions.

Thermal analysis of servomotor
Přibyl, Daniel ; Duroň, Jiří (referee) ; Klíma, Petr (advisor)
This thesis deals with the design of the thermal model of servomotor in program Motor-CAD and using it for analyze of servomotor. In the beginning is a short familiarization about its parts, especially important for the thermal model. Further are described principles of heat exchange. There is a chapter, which is dedicated to the program support of the Motor-CAD. Thermal model and electromagnetic model inputs are tuned according to the measured data. Then a way of active cooling is designed and based of it the model in program is edited. Using the model is found the points of load of the motor for maximum allowable temperature with water cooling. In the conclusion is a valorization of benefit of water cooling for the servomotor.
