Single-Phase Induction Motor Calculation
Schlesinger, Petr ; Vítek, Ondřej (referee) ; Hájek, Vítězslav (advisor)
This master’s thesis’s target is to introduce the basic findings about single-phase asynchronous motors, their derivation from three-phase motors and the basics of a computation process and a concept of a single-phase asynchronous squirrel cage motor. The inbeing of this concept and the computation is created by classical processes for three-phase motors with a low voltage, 50 Hz.

Mathematical models of the transformers and asynchronous machines
Cipín, Radoslav ; Běloušek, Josef (referee) ; Patočka, Miroslav (advisor)
The fist part of this work is dealt with the construction of the mathematical models of voltage and current transformers. There are created and simulated models of voltage and current transformer with the nonlinear magnetization characteristics. The second part of this work is dealt with equivalent circuit of the induction motor in the form of Gamma-circuit. The speed-torque characteristic and the dependence of stator current on the slip are calculated from this equivalent circuit. The third part of this work is dealt with electromagnetic design of the alternating current machines by the help of a classic way and a new way.
