“…Consequently, the circuit and field equations are indirectly coupled. A general method to perform a direct coupling of static converters and electromagnetic devices considering closed loop control strategies is described by Roel Ortiz et al (2001). The switching control signals are generated automatically according to the value of the variable to be controlled and the control law.…”

This paper presents a method to analyse electrical machines considering simultaneously the electromagnetic field, electric circuit, control loop, movement and skewing effects. The major contribution of this work leans on its generality, i.e. it can be applied to electrical machines connected to static converters submitted to any control laws, avoiding an a priori analysis. Simulation results of a three‐phase Brushless AC (BLAC) motor fed by a PWM converter is presented as well as a comparison of simulation and experimental results obtained using a two‐phase‐on converter were also presented.

Purpose -This paper aims to give a perspective about the variety of techniques which are available and are being further developed in the area of coupled field formulations, with selective bibliography and practical examples, to help postgraduate students, researchers and designers working in design or analysis of electrical machinery. Design/methodology/approach -This paper reviews the recent trends in coupled field formulations. The use of these formulations for designing and non-destructive testing of electrical machinery is described, followed by their classifications, solutions and applications. Their advantages and shortcomings are discussed. Findings -The paper gives an overview of research, development and applications of coupled field formulations for electrical machinery based on more than 160 references. All landmark papers are classified. Practical engineering case studies are given which illustrate wide applicability of coupled field formulations. Research limitations/implications -Problems which continue to pose challenges to researchers are enumerated and the advantages of using the coupled-field formulation are pointed out. Practical implications -This paper gives a detailed description of the application of the coupled field formulation method to the analysis of problems that are present in different electrical machines. Examples of analysis of generators and transformers with this formulation are presented. The application examples give guidelines for its use in other analyses. Originality/value -The coupled-field formulation is used in the analysis of rotational machines and transformers where reference data are available and comparisons with other methods are performed and the advantages are justified. This paper serves as a guide for the ongoing research on coupled problems in electrical machinery.

PurposeThe purpose of this paper is to calculate the electromagnetic torque at a radius of an integration contour for which an optimal value is determined.Design/methodology/approachTo analyze electrical machine dynamics, the electromagnetic torque should be precisely determined. This paper presents a method for calculating the torque, where the radius of the integration contour is variable and estimated from the field distribution.FindingsThe electromagnetic torque of the three‐phase AC motor model proposed in TEAM Problem No. 30 is estimated using the proposed method. The obtained results are compared to solutions obtained analytically.Originality/valueThis paper examines the application of the presented method to determine the electromagnetic torque in three‐phase AC motors.
