Stator winding short-circuit faults are among the most common faults that could occur in permanent magnet synchronous machines (PMSM). Therefore, on-line diagnosis of incipient stator winding short-circuit faults plays an important role contributing to the safe operation of PMSMs. However, the efficacy of known diagnostic methods varies with the types of stator winding configurations in PMSMs. This paper compares the effectiveness of diagnosis of stator winding short-circuit faults in series and parallel winding connections of PMSMs, with the same interior permanent-magnet rotor configuration. Two existing diagnostic methods have been applied to detect the severity of stator short-circuit faults happening in both series and parallel winding connection in PMSMs. Simulation analysis has been carried out in ANSYS Maxwell to compare the severity of magnetic saturation caused by equivalent short-circuit fault in series and parallel winding connected PMSMs. Experimental results lead to the conclusion that PMSMs with parallel winding connections can mask the influence of such stator short-circuit faults under certain circumstances, and thus it is more challenging to detect such incipient faults in parallel-winding-connected PMSM in comparison with series-winding-connected PMSMs.

This paper investigates the application of multisensor fault feature extraction and fuzzy-logic based clustering for the condition monitoring of bearing. Multiple independent sensors on an electric motor drive system provide valuable early indication of a fault, and can be effectively utilized to perform high reliable and optimal fault detection. Through utilizing common sensors including current sensor and vibration sensors in motor, motor current signature analysis (MCSA) and vibration analysis have been used to extract the bearing fault energy. The discrete wavelet transform (DWT) has been applied to monitor energy of the bearing fault signals. Then, the fuzzy c-mean (FCM) has been developed to utilize the data from single sensor and multisensor to identify the severity of bearing fault. Extensive theoretical analysis and experimental test has been performed to demonstrate the advantages of proposed approach. The validity of this study has been confirmed through analysis of the 1/6 HP single phase induction motor and drive system.

In general engine generators, the engine and generator are separate units connected by a mechanical coupling. This tends to increase the package size of general engine generators. In this paper, we are able to achieve miniaturization and high output power of the generator by adopting an axial-gap structure through using ferrite permanent magnets. At the same time, the package size is reduced dramatically by integrating the axial-gap generator into the engine. This paper also discusses methods for reducing the eddy current losses that occur in the windings due to the open-slot structure of the stator core and occur in the rotor support component. By using results from three-dimensional finite element analysis, we show that the eddy current loss that occurs in the windings is reduced by using appropriate methods to wind the coils with rectangular wires. In addition, the eddy current loss that occurs in the rotor support component is decreased by appropriately selecting the material and changing the shape of the component. Experimental results show that the studied structure is effective for realizing miniaturization and high output power of the generator, as well as for decreasing the package size of the engine generator.

To realize energy saving in electrical appliances and electric vehicles, it is necessary to reduce the power consumption of motors operating at variable speeds. We developed a technique that changes the poles of a permanent magnet (PM) motor depending on the speed. Here, we propose a novel PM motor that changes the number of poles without changing the winding connections and discuss its basic configurations and principles. Pole-changing is accomplished using the d-axis current of the proposed motor for magnetization. Our analysis results confirm that the pole-changing PM motor reduces iron loss by 36% over a conventional PM motor and increases efficiency over a wide range of speeds. Hence, the proposed motor is suitable for use in variable-speed drive systems to achieve high performance and efficiency.

Magnetohydrodynamic power generation (MHDG) was a thriving field of research in the 1960s but low efficiency and difficulty to reach desired operating points (high temperature) discouraged the investment of further efforts in the matter. Nowadays technological advances such as superconducting electromagnets (with very low power consumption for higher overall efficiency), power electronics (to enable harvesting and processing of current intensive DC power for any application), and powerful multiphysics simulation software, call for a reassessment of this power generation method. The aim of this paper is to deliver a realistic analysis of the competitiveness of MHDG as well as the possibilities offered by design variables to improve its attributes. Finite element analysis offers an improved understanding of field and flow distribution as well as the power density generated within the fluid channel. Analytical energy efficiency determination is completed for two different fluids as well as a sensitivity study of influential design factors. Furthermore a power output/cost comparison between MHD-systems operating with combustion gasses and liquid copper is carried out to offer a complete assessment of MHDG.

To reduce the cost of energy of offshore wind energy conversion, large individual wind turbines of 10 MW or higher power levels are drawing more attention and expected to be desirable. Conventional wind generator systems would be rather large and costly if scaled up to 10 MW. Direct drive superconducting generators have been proposed to reduce the generator size, because the electrical machines with superconducting windings are capable of achieving a higher torque density. However, a superconducting machine is likely to produce an excessive torque during a short circuit because of its small reactance. An electromagnetic (EM) shield between the rotor and the stator as well as iron or non-magnetic composite (NMC) armature teeth affects the sub-transient reactance of a superconducting machine so that they play a role in the short-circuit performance of a superconducting wind generator. This paper presents a 10 MW superconducting generator design and studies the effects of material, thickness and position of an EM shield and the effects of NMC and iron armature teeth on the torque and the field current density during a three-phase short circuit at the generator terminal. One result shows that the short circuit torque is not able to be effectively reduced by varying the EM shield and the armature tooth material. The other result shows that the field current density is likely to exceed its critical value during a short circuit although the EM shield material and the armature tooth material take some effect.

In this paper, a Lyapunov based finite control set model predictive direct torque control for the permanent magnet synchronous machine (PMSM) is proposed. In the proposed control scheme, the finite control set prediction and the Lyapunov theory are combined to minimize the torque ripple. The 8 voltage vectors of the 2-level converter are utilized as a finite control set for the torque prediction of the PMSM. A cost function considering the torque error, the Maximum Torque per Ampere (MTPA) operation and the current limitation is introduced. Comparing to the conventional finite control set predictive control, the dominant part of the cost function is utilized as a Lyapunov function to estimate the duty cycle of each voltage vector. An optimum voltage can be obtained by the optimum voltage vector from the 8 vectors and their duty cycles. A small sampling frequency and a fixed switching frequency can be realized when compared to the conventional finite set model predictive control. In the end, the simulation and experimental results validate the performance of the proposed control scheme.

In this paper a closed-form 2D analytical model developed for the estimation of eddy current loss in interior permanent magnet machines is presented. To check the generality of the developed model, two different types of commonly employed interior permanent magnet machines are considered. 2D finite-element analysis was used to benchmark the results from the analytical model. The proposed model can be directly used to evaluate the eddy current magnet loss for magnet segmentation in the circumferential direction. The influence of air-gap length, frequency of carrier harmonic, reaction field and non-linearity of iron due to saturation on the magnet loss have been studied in detail and the results are presented. The effect of axial segmentation has been considered by incorporating an end-effect factor in the analytical model. The results from analytical and 2D finite-element analyses are found to be in concurrence.

The closed-loop speed control for a high speed switched reluctance machine (SRM) is studied in this paper. A speed-and-current dual closed-loop control scheme is selected for speeds as high as 50 krpm. The novelty of the proposed control method is inclusion of the inductance profile selection for a flux-bridge rotor. In this paper, the nonlinear SRM is modeled in a linearized form by small signal equations, and then transfer functions are used to calculate the appropriate controller coefficients. The proposed control scheme is designed and its performance is evaluated using Matlab/Simulink.
