Electromagnetic Field Calculation of IM for Different Equivalent Circuit Parameters
Skalka, Miroslav ; Schreier, Luděk ; Ondrůšek, Č.
This paper contains a calculation of electromagnetic field distribution of Induction machine for different equivalent circuit parameters due to the loads - each step is calculated for different rotor and stator currents. The definition of parameters and the real values of rotor and stator currents were presented on the XVI. Inter. Symposium on Electric Machinery in Prague. These data were used for a calculation of electromagnetic field distribution of Induction Machine (IM) by finite element method in ANSYS.
Analysis of Steady-State Operation of Induction Generators
Schreier, Luděk ; Bendl, Jiří ; Chomát, Miroslav ; Skalka, Miroslav
The paper deals with the problems associated with the estimation of the magnetizing current in generator operation of induction machines. The aim of this paper is to show possible rise of over-saturation of magnetic circuit in induction generators. The results may be used for more precise specification of parameters of an induction machine in different operating modes.
Analýza chodu pohonů s proměnnými otáčkami využívajících jednofázové motory
Chomát, Miroslav ; Schreier, Luděk ; Bendl, Jiří
Variable-speed operation of drives with single-phase machines is investigated. Drives of two different configurations are considered and compared to each other in the paper. Maximal achievable torque and amplitude of torque pulsations in various modes of operation are discussed.
