| Abstract |
The paper presents development and validation of a
dynamical model and an equivalent circuit for a single-phase
induction machine supplying a position-dependent load. The
problem has a major industrial significance, as it arises in a
number of applications, such as compressors in airconditioning
systems. Conventional models are not accurate
enough for basic design studies like efficiency calculations,
necessitating laborious time-domain simulations that reveal
little about the sensitivities to design parameters. The
proposed solution is based on dynamic phasors, which is a
systematic methodology for derivation of low-order nonlinear
models for energy conversion systems. |
