This contribution deals with an optimal design of a brushless DC motor, using optimization algorithms, based on collective intelligence. For this purpose, the case study motor is perfectly explained and its significant specifications are obtained as functions of the motor geometric parameters. In fact, the geometric parameters of the motor are considered as optimization variables. Then, the obj...

A comparative study of the various methods for design of an induction motor is presented. This deals solutions of a large number of non-linear equations and consequently some modifications of the methods have been suggested for use in practice. Modifications of the gradient theory, dynamic programming and statistical search is also made for optimal design. Besides, dual criteria optimization pr...

Due to the nonlinearity of IMs (Induction Motors), design optimization of these motors, using simple optimization methods, are not applicable, and modified methods are necessary. IMs have many different characteristics that must be optimized. In this paper, using weighting method, multi-objective design optimization of IM reduced to a new objective function that can be optimized simply using FE...

In this paper, a field oriented control (FOC) induction motor drive is presented. In order to eliminate the speed sensor, an adaptation algorithm for tuning the rotor speed is proposed. Based on the Model Reference Adaptive System (MRAS) scheme, the rotor speed is tuned to obtain an exact FOC induction motor drive. The reference and adjustable models, developed in stationary stator reference fr...
