This paper presents a non-linear dynamic model of a permanent capacitor single-phase induction motor. The D–Q axis model of the permanent capacitor induction motor, based on the state vector analysis of the system is conducted; revealing the periodic and chaotic phenomenon under different system parameters. Accordingly, a chaotic-speed fan can be achieved by appropriately varying the motors’ in...

For the kilometer-level electromagnetic launch system, a high-speed double-sided linear permanent magnet (PM) motor is presented in this paper. To enhance average thrust force, reduce ripple and normal force of motor, segmented trapezoidal PM shaping method proposed. Compared with conventional method, PMs achieves less ripple, greater lower manufacturing difficulty. The risk demagnetization fau...

This paper presents an optimal design method to optimize three-phase induction motor in manufacturing process. The optimally designed motor is compared with an existing motor having the same ratings. The Genetic Algorithm is used for optimization and three objective functions namely torque, efficiency, and cost are considered. The motor design procedure consists of a system of non-linear equati...

In this paper the dynamic behavior of linear induction motor is described by a mathematical model taking into account the end effects and the core losses. The need for such a model rises due to the complexity of linear induction motors electromagnetic field theory. The end affects by introducing speed dependent scale factor to the magnetizing inductance and series resistance in the d-axis equiv...

in this research using the theory of induction motor (um), a um with liquid as secondary part is planned and manufactured. the main objective for planning of this motor is to investigate the possibility of chemical liquids pumping such as liquid poison and acids. results of many laboratory tests are shown to conclude that pumping force in the manufactured pump is dependent on many factors su...
