“…The temperature dependence of stator resistance results in inaccurate performance prediction if temperature is not taken into account in advance [3]. Estimation of both stator and rotor resistances are dealt with, in order to monitor the thermal behavior of the induction machine in real time.…”

Induction machines (IMs) are today widely used in various applications. For example, it is by far the most used electrical motor in industry. Asynchronous motors, particularly the squirrel-cage induction motor, enjoy several inherent advantages like simplicity, reliability, low cost and virtually maintenance-free electrical drives. These facts are due to the induction motor advantages over the rest of motors. The main advantage is that induction motors do not require an electrical connection between stationary and brushes. Induction motor also has low weight and inertia, high efficiency and high overload capability. In addition, due to its practical importance, tremendous amounts of money are still spent today on research regarding its physics and operation. The range of possible research subjects pertaining to IMs is beyond belief. Covering all results and all references available in the literature could easily fill up a thesis all by itself.

“…In fact, the use of four‐phase induction machine drive system was recently proposed as an alternative to eliminate the common mode voltage (Azevedo et al , 2001). Moreover, the use of a four‐phase machine contributes to reduce the rating of the power switches and provides some fault‐tolerant characteristics for the drive system ( Jacobina et al , 2002). Finally, four‐phase switched reluctance motors are suitable for high‐speed applications (Dessouky et al , 1998).…”

PurposeTo provide a unified analytical tool for the theoretical and practical analysis of four‐phase systems under sinusoidal condition but also under dynamic condition and to understand the contribution of each sequence components on the energy and air gap field points of view.Design/methodology/approachStarting from the general procedures of analysis for the n‐phase symmetric systems, the analysis of four‐phase system is first developed in the phasorial domain, then, with reference to the asymmetrical sinusoidal conditions in terms of symmetric components. As a complement to what is already present in the literature, finally a formalization of the four‐phase systems in an instantaneous form based on the Lyon and Clarke‐Park vectors is proposed. Furthermore, a particular emphasis will be given to the physical meaning of the involved quantities, to their link with the three‐phase quantities and to the instantaneous energetic interpretation.FindingsFour phase system presents the existence of the pseudozero‐sequence component which is an additional descriptive variable of the four‐phase configuration, absent in the three‐phase system. Pseudozero‐sequence component results completely independent on the need for a neutral wire. Knowledge of the Park vector is as much as necessary to generate the field in the air gap.Practical implicationsThe four‐phase systems methodological analysis presented in this paper is very helpful for the formalization of the theoretical and applicative methodologies necessary for the development of four‐phase systems in a systematic and unified way.Originality/valueThe four‐phase systems analysis is presented in this paper both for the sinusoidal and the variable conditions. Furthermore, the role of the pseudozero‐sequence component, not present in three‐phase case, and its implications in circuital terms have been investigated with attention. Finally, the energetic side and the definition of the correspondent instantaneous and average powers have been investigated as well.

“…The use of dual-winding machine drive systems simplifies the on-line estimation of the model parameter's [1], contributes to reduce the ratings of the power semiconductor devices, provides fault-tolerant features and allows for mitigating the common mode voltage [2], [3], [4]. On the other hand, the study of topologies with reduced number of switches is an important topic in power electronics [5][6][7][8][9][10][11][12].…”
