Optimization of the cooling of induction machines
Halfar, Ivo ; Dostál, Lukáš (referee) ; Janda, Marcel (advisor)
This master‘s thesis deals with problems of optimization of cooling in electrical machines. This work includes introduction to the theory of mathematical optimization and brief introduction to optimization problems. This thesis deals with using of program Ansys Workbench for the thermal analysis in electrical machines and optimization of their cooling. Thesis contains thermal analyse of specific asynchronous motor with the squirrel cage and optimization of its cooling.
Experimental stand for properties verify of heat pipe in the electric machine shaft
Kučera, Jaroslav ; Cipín, Radoslav (referee) ; Vlach, Radek (advisor)
My bachelor thesis follows my semestral work, which was devoted to the design of the measuring station simulating the cooling of the rotor of the electric machine using a thermal tube in the shaft, and extends it to a practical test, where the measurement verifies the correctness of my design and the proper functioning of all its parts. During the measurement, the software was modified to provide more accurate temperature control in the heated chamber. The basic assumptions have been confirmed. As has been demonstrated during the experiments, greater attention should be paid to the material for the formation of chambers.
