The article presents simulation and experimental examination of a single-phase commutator motor considering non-linearity of the magnetic chain and core losses with a mathematical model, created with MATLAB-SIMULTNK. In the material it is also presented an examination of some typical regimes as start, stop and power reverse: constant voltage, ...

A mathematic model of the electromechanical transients in single-phase commutator motor is developed which take into consideration non-linear variation of the winding inductances and magnetic flux as they depend by armature current. The influence of the armature winding reaction is take into account as for the computing of the magnetic ...

A possibility for extending the speed control range of conventional induction motors under pulse control is treated. This is obtained by connecting capacitors in series to each phase of the motor. As a results, the short circuit reactance whill be decreased, the critical slip whill be increased and the control range whill be extended. Both ...

In this paper an asymmetric state in a cage rotor using symetrical components method is considered. Many cases of asymmetry namely brakings, finite changes of resistances of bars are investigated. Determining of syrnetrical components is done based on set of equations with order much less than number of phases of rotor. A method for finding ...

: In this paper are presented algorithms of calculation of the control laws of a single-phase commutator motor by electronic control. The single-phase commutator motors are nonlinear devices those can operate with alternative or direct current supply and by that mean the algorithms are developed about these two cases. For calculation of the ...
