Condition Monitoring on rotating electrical machines has proven to be economically beneficial in the last decades, especially for industrial production processes. Vibration analysis has already become a reliable and commercial tool to perform condition monitoring or predictive maintenance. Stator current analysis, a newer technology that is still being developed can possibly open new perspectives and opportunities in the world of predictive maintenance. This technology is also known as Motor Current Signature Analysis or MCSA. In this paper the advantages and disadvantages of both technologies are listed and compared from a practical point of view, supplemented with a case study. The case study contains a bearing fault detection in an induction machine driven by a frequency converter. The machine drives a fan with varying torque and speed conditions.

Rotor eddy-current loss calculation by means of 3D finite element analysis is often necessary during later design stages of a new machine, but can still be very time-consuming. This paper proposes two FEM-based methods that potentially require less time to solve than a transient model of the complete machine geometry and are relatively straightforward to implement. Both methods apply an airgap boundary condition obtained from a limited number of solutions of a full 3D model, to a model containing only the rotor geometry. An important property of both methods is that they can account for shielding effects in the rotor. The performance of the methods in terms of accuracy and speed is demonstrated and guidelines for implementation are presented, showing that the rotor losses can be calculated 2-3 faster without loss of accuracy. Finally, using the methods a number of rotor loss trends are confirmed.

Partitioned stator (PS) machines employ two separate stators to accommodate armature windings and permanent magnets (PMs) respectively, alleviating the stator space conflict in stator-PM machines and hence significantly boosting the torque density. However, the PM usage volume of PS machines is relatively large and the cost is high, which is undesirable for cost sensitive applications. In this paper, a PS machine employing ferrite PMs is presented, which can take the advantage of large space for PMs in PS machines as well as balance the performance and cost. The electromagnetic characteristics of an optimized ferrite PS machine and an optimized NdFeB PS machine are compared, together with a classic Prius2010 interior-PM (IPM) machine as a baseline for comparison. In addition, the economic issues are considered as well. The predicted results reveal that the NdFeB PS machine can produce much higher torque density but is more expensive than the Prius2010 IPM machine, whilst the ferrite PS machine can significantly reduce the cost and still exhibit comparable performance as the Prius2010 IPM machine and the highest torque per cost. The demagnetization behavior of ferrite PS machine is evaluated and a method to improve the demagnetization withstand capability is proposed. A pair of scaled prototypes are manufactured to validate the finite element predictions.

This paper presents a new sliding-mode observer (SMO) for interior permanent-magnet motors (IPM) to be utilized in sensorless field-oriented control (FOC) algorithms. Due to IPM's rotor saliency, the traditional back electromotive force (back-emf) model for surface-mount permanent motors (SPM) cannot be used in IPM observers directly. In order to address this problem, the extended electromotive force (EEMF) model is adopted for observer design. Unlike many other EEMF model based SMOs, the phase delay mitigation algorithm (PDMA) integrated in the proposed observer significantly reduces steady-state estimation error while maintaining low-pass filter's dynamic performance. The simple structure makes the proposed observer an ideal candidate for cost-sensitive applications which guarantees satisfactory performance and efficiency. Theoretical analysis, simulation and experimental results are provided to validate the fidelity of the proposed SMO.

Parasitic losses, including PM and iron losses, in novel 12-stator-pole partitioned stator switched flux permanent magnet (PS-SFPM) machines with double- and single-layer windings are comparatively analyzed by 2-dimensional finite element method (FE) in this paper, together with the influence of different stator/rotor-pole combinations, i.e. 12/10, 12/11, 12/13, 12/14 stator/rotor poles. FE results show that 12/11 poles PS-SFPM machine has the highest PM and iron losses in the cases of both double and single-layer windings, whilst the 12/14 counterpart has the smallest ones.

The effects of the three level inverter on the core losses of a SynRM are investigated particularly at the stator yoke and tooth. A comparative study on the effects of space vector pulse width modulated (SV-PWM) two and three level inverter on the iron/core loss are analyzed. A SynRM stator made of silicon steel, M36, 0.35 mm thickness is used. The machine was driven from a two and three level inverters and the current waveforms where used in the finite element model so as to capture the flux densities. The SynRM stator was then excited by these flux density waveforms obtained from the FE model. Tests were conducted at 30 Hz, 60 Hz and 180 Hz and there was an approximate 6 % reduction in core losses at 180 Hz under a three level inverter drive. The reduction in core losses were significant on the stator tooth than on the stator yoke. The use of a three level inverter will reduce the burden of the cooling system on the machine.

Because of the wide range of application of BLDC (brushless DC) motors, the fault diagnose of BLDC becomes an essential problem. For those BLDC motors in application, rotor faults account for most of the faults in BLDC motors. Static eccentricity and dynamic eccentricity are two of the main faults in the rotor of BLDC motor. In this paper, an improved method detecting static eccentricity is proposed based on the comparison between the positive sequence current and negative sequence current. Comparing to the traditional method which only focuses on the change of the negative sequence of fundamental frequency current, the method proposed in this paper could be more reliable since the positive sequence current and harmonics current are considered as well. A BLDC motor with static eccentricity in AHU (air handler unit) will be tested. The effectiveness and availability are verified in both simulation and experiment results.

A major source for torque ripple is the harmonics in airgap permeance caused by stator slotting, permanent magnet (PM) flux barrier, etc. They are reflected in the flux linkages of the stator windings. In this work, we express the d and q-axis flux linkages as Fourier series after obtaining them using finite element analysis (FEA). Torque ripples are obtained analytically using the Fourier coefficients of the flux linkages, and justified by comparing the results with FEA torque. With a linear flux model in current, the ripple components are expressed explicitly in current and high order saliency. Through simulations, it is demonstrated that the ripple increases as the d-axis current increases negatively along a constant torque line.

The purpose of this paper is to introduce a novel dual-stator six stator slots four rotor poles flux switching permanent magnet machine that is viable for operation. The conventional six slots four poles topology suffers from asymmetrical flux linkage and severely unbalanced back-EMF, which makes it unfeasible. The proposed dual-stator structure utilizes windings in the second stator to produce a corresponding flux linkage that cancels the even order harmonic components in the first stator winding. The resulting flux linkage, back-EMF have no even order harmonics and are almost sinusoidal waveforms. The performance of the proposed machine is validated by analytical and finite element analysis.

High fidelity ac machinery models including harmonic effects are becoming increasingly desirable for use in improved fidelity machine and drive behavior analysis. This paper describes a method enabling the development of a dynamic induction machine model in SIMULINK which has a capability of representing time and space harmonic effects. The manuscript first presents the details of the model development and implementation. The proposed model performance is then validated through comparison with experimental current and torque signals data obtained from two separate induction machine laboratory test rigs. The results show a good agreement between measured and predicted data in the frequency domain and validate the competency of the presented model in representing harmonic effects.
