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.

Vliv vybraných parametrů na vlastnosti asynchronního generátoru
Schreier, Luděk ; Bendl, Jiří ; Chomát, Miroslav
The paper deals with the problems associated with the estimation of the magnetizing current in generator operation of induction machines. According to some experts, the magnetizing current in generator operation is considerably bigger than that in motor operation and this fact must be taken into consideration while designing the magnetic circuit. It is shown that this opinion is not justified in case of generators with output power about 30 kW and higher.

Příspěvek k analýze ustáleného chodu asynchronního stroje
Schreier, Luděk ; Bendl, Jiří ; Chomát, Miroslav
The paper deals with the problems associated with the estimation of the magnetizing current in generator operation of induction machines. According to some experts, the magnetizing current in generator operation is considerably bigger than in motor operation and this fact must be taken into consideration while designing the magnetic circuit. It is shown that this opinion is not in many cases quite justified and thus it is not necessary to overrate the magnetic circuit and an induction machine originally designed as a motor can be used as a generator without derating.
