Several methods are available for performance prediction of single phase shaded pole induction motors. A simple model, in conjunction with a more complicated and accurate model, which considers the asymmetrical windings and core loss, is used to compare the prediction methods against experimental results. Saturation is incorporated in the model. Fundamental and harmonic flux density wave distri...

The current standard considers the efficiency of electric motors only in terms power and does not pay attention to so-called economic - factor that affects loss electricity motor supply network depends on its energy excellence.This ill-considered approach establishing class is a significant shortcoming European requires refinement. single-phase housing communal services has led fact modern comp...

introduction: spastic hemiplegia is one of the most common types of cerebral palsy. pathology of the central nervous system can alter normal development of the somatosensory cortex and develop sensory deficits. these deficits can decrease upper limp motor performances and skills and reduce the tendency to use the affected upper limp, so the quality of life is impaired in these children. therefo...

Single-phase induction motors have a wide range of domestic and industrial applications. These motors have a squirrel cage rotor and their stator usually has two windings: main and auxiliary. The use of auxiliary winding in the structure of single-phase induction motors creates two unbalance and asymmetric phases. This causes to increase the spatial harmonics of the field in the air gap, and al...
