Abstract
This dissertation focuses on the transient and dynamic analysis of the line-start novel synchronous reluctance motor (SynRM) with a sinusoidal rotor shape.The line-starting capability of the novel SynRM is achieved by inserting brass bars in the flux barriers on the d-axis and in the iron laminations close to the airgap on the q-axis, and the bars are short-circuited by brass end rings. The brass used for both bar and end ring are made up of copper, zinc and tin to prevent dezincification on numerous conditions.The thin brass bars has pleasant force,upper resistance to atmospheric and water corrosion,and good electrical power. The mathematical model that illustrates on the dynamic behaviour of the novel SynRM with brass rotor bars was developed in both machine variables and arbitrary rotating frame to establish the relation between different quatities. To analyse the effects that the different quantities in the dynamic model have on the machine’s electromagnetic performace, the 3-Dimension (3-D) Finite Element Method (FEM) was used to design and model the novel SynRM with brass rotor bars.A 3-D Finite Element Analysis (FEA) model was executed for the non-linear AC magnetic transient solution to analyze the transient execution of the proposed motor.
