“…ForaWinding Function Approach (WFA) model which accounts for all the space harmonics in the machine, the differential equations predicting the performance of an mphase induction machine with n rotor bars are derived in [8] [9][10] [11]. This model is adopted the coupled magnetic approach by assuming the current in each rotor bar as an independent variable.…”

This paper discusses a novel method for motor fault detection under varying load conditions. Winding Function Approach (WFA) is used to develop a mathematical model to provide indication references for parameters under different load levels and different fault situations. Broken bar defects reference indexes are developed to assess rotor fault severity based on stator current and rotor speed. Stator current and rotor speed are used to demonstrate correlations between these parameters and broken rotor bar severity. Simulations and experimental results confirm the validity and effectiveness of the proposed approach.

“…It is worth noting that nearly all the papers that describe the control scheme of a multiphase induction motor with high torque density choose a value of the third spatial harmonic of the air-gap field that is deduced from a well-established method, namely the maximization of the amplitude of the fundamental component of the air-gap field [10], [12], [13].…”

Nowadays, there is an increasing interest towards multi-phase motor drives, i.e. with a number of phases greater than three, especially for medium and high power applications such as naval and railway propulsion systems.It is known that multiphase motors offer the opportunity to increase the torque density by adding a third spatial harmonic in the magnetic field.In this paper the problem of maximizing the torque capability in multiphase drives based on induction motors by adding a third spatial harmonic in the air-gap field is investigated in depth. The analysis shows that not considering the inverter and motor current rating may lead to suboptimal motor performance. The validity of the theoretical analysis is verified by numerical simulations and experimental results.

“…The modelling approach outlined above is utilized e. g. in [4], where the feasibility of describing a squirrel-cage rotor by only a few equations is advocated. The paper also describes how the individual currents in the rotor bars can be derived from the reduced order model.…”

In this paper, a low differential order model describing the dynamics of IMs with faulty stator is developed. The modelling is performed under well established idealizing assumptions regarding the magnetic and electrical properties of the motor. Typical motor faults as inter-turn short circuit and increased winding resistance are taken into account. The resulting model can be handled analytically and serve as a ground for fault detection and fault tolerant control of the IM. For each of the considered faults, very good agreement between simulations and experimental data collected from mass-produced industrial IMs is observed. NomenclatureVariablesFor both the variables and parameters, a capital letter subscript refers to the corresponding stator axis in a conventional three-axis system. Similarly, a small letter subscript refers to the corresponding rotor axis. The units for the variables and parameters are SI-units which are omitted for the sake of clarity. Throughout the paper, bold capital letters stand for matrices, whereas small/capital letters denote scalars and vectors. Finally, differentiation with respect to time is denoted by the dot, i.e.ẋ = dx dt .
