Measurement of induction machines
Sporni, Peter ; Huzlík, Rostislav (oponent) ; Janda, Marcel (vedoucí práce)
This work dissert about problematics of induction engines, which are the most used types of electrical drives used in present time. At the beginning we will explain their construction and its influence to the characteristics of the engine and possibilities of their regulation. In the next part we will describe some basic types of measurments implemented on these engines. To verify the theory which was described in this work we will discuss measurments realized on concrete types of engines. At the end we will calculate the main dimensions for one of the measured engine.

Model of synchronous PM machine based on equivalent reluctance network
Sporni, Peter ; Lapčík, Josef (oponent) ; Ondrůšek, Čestmír (vedoucí práce)
This work disserts the problematics of creating and simulating reluctance network of the synchronous machine with V-shaped permanent magnets in the PSpice software. Firstly we familiarize with the construction and parameters of the machine and then we educt basic equations to calculate each component of the network. We calculate each component on the machine and then we create this network in PSpice. At the begining the simulated network is static and all magnetic resistivities are linear which gives us higher magnetic flux densities. Later we replace the steel sheets linear resistivities with nonlinear and we calculate also with working temperature of the permanent magnets. Then we compare our results with FEM method calculated values and we also calculate the induced voltage in one coil of winding. At the end we calculate power and torque characteristics of the machine.
