Abstract
Asynchronous induction motors are large consumers of electrical energy. They are widely used in different industrial applications although their usage is often limited by low power and efficiency factor. Often they are replaced by synchronous motors especially in applications with wide range of speeds and high dynamic performance is required. Model of the asynchronous squirrel cage motor for calculating parameters and characteristics is derived and obtained results from this model are compared with experiments. The synchronous motor with surface mounted permanent magnets is constructed from the asynchronous motor without changing the stator configuration and for the constant power application. Parameters and characteristics of both motors are calculated, compared and analyzed leading to the conclusion of improved characteristics of the synchronous motor in terms of the efficiency for the same power rating. Cogging torque of the synchronous motor is calculated and parametric analysis of the motor is set resulting in the improved model of the synchronous motor with decreased cogging torque and improved dynamic response. All motor models are analyzed with Finite Element Method and magnetic flux density in cross-section of the motor models is obtained as well as transient performance characteristics. FEM models verify the accuracy of the proposed motor designs.
