Voltage ripple in DC tachogenerators with magnetic armature asymmetry.
Abstract
The influence of the asymmetry of the magnetic system on the level and spectrum of the voltage pulsations of the dc tachogenerator is considered. A model was developed and mathematical expressions were obtained on its basis, which allow calculating the instantaneous value of the emf in the presence of asymmetry of the magnetic system. The calculated curves are given, which make it possible at the design stage to determine the dimensions of the tachogenerator inductor for certain types of asymmetry of the magnetic system from a given level of pulsations.
