GENERALIZED MODELS OF POWER EFFICIENCY OF INDUCTION MOTOR, WITH VOLTAGE CONVERTERS IN CIRCUIT OF STATOR
Journal Title: Інженерні та освітні технології - Year 2013, Vol 1, Issue 1
Abstract
The questions of design and research of power efficiency are consider induction motors at multivariable variations of combinations of regime, types of loading, method of voltage modulation and parameters of pulse voltage converter. The method of calculation of changes of losses in induction motors, with voltage converters in circuit of stator is developed, different the account of method pulse-width modulation of voltage, frequency and duty cycle. Research and prognostication of change power efficiency of work was executed induction motors at the change of parameters of impulsive and unnominal feed-in voltage and loading. The methods of increase of power efficiency of work are offered induction motors by the purposeful change of combination of regime.
