Losses of capacitor run induction motor
Štaffa, Jiří ; Hájek, Vítězslav (referee) ; Mach, Martin (advisor)
This project deals with increasing efficiency of one phase induction motor with permanent split capacitor. We can whole thesis divide into two parts, the first one is basic and the second is interested in analysis and measurement. First part handles with construction of single phase induction motor, explanation of function principle, start and run of motor. Calculating of efficiency including type of losses, which reduce efficiency. Second part concerns analysis losses including moment load characteristic, motor measurement while rotor is locked, with no load operation, measuring mechanical and additional losses. Further there will be measured useful values for creation model for simulation (reactance of windings etc.). Than will be the model created in ANSYS Maxwell with module RMxprt. After analytic calculation in RMxprt and using Finite Element Method (FEM) load characteristics will be compared together. This comparison gives us information about accuracy of model for simulation. Simulation and measurement will be carried out on another engine with high quality ferromagnetic material used for magnetic circuit of motor. Further will be done simulation of motor with modifications shown in previous chapter for high efficiency.

Impact of core length on efficiency of a single phase induction machine
Binek, Martin ; Hájek, Vítězslav (referee) ; Mach, Martin (advisor)
This bachelor's thesis analyses the impact of core length on efficiency of a single phase induction machine with a run capacitor in the auxiliary winding. The whole thesis can be divided into two parts. The first part of the thesis includes general knowledge concerning single phase induction machines and technical base for its analytical calculation. The second part works with the actual technical documentation of a motor. This part includes creation of the motor model in RMxprt module, analytical calculation for verifying the motor properties and laboratory measurement, where the results are primarily compared to RMxprt simulation as well as to the analytical calculation, mainly from the efficiency perspective.
