Abstract
This thesis deals with the design and investigation of
the steady state performance characteristics of saturistor
induction motors, using a new model of saturistor represent
ation in cage rotors.
A general revision on the previous literature during the
last 20 years is presented, and different models of saturistor
representation in single frequency equivalent cirauts are also discussed and investigated. A new representation is then
introduced which considers the actual magnetic properties of
saturistor materials. Also, the fundamental component of
magnetizing current is considered to be the component which
produces the saturistor loss. As a result, the harmonic
currents are ignored in case of single frequency sinusoidal excitation. With this new concept, characteristic, curves of saturistors are obtained., considering the effect of the
saturistor volume and air space in its magnetic flux path.
A comparison between different representations of saturistors in single frequency equivalent circuits is also included.
The work has applied the new model representation to
investigate the steady state performance of squirrel cage
saturistor induction motors, using the conventional equivalent
circuit approach. A.,--digital computer is prepared to compute
