Wide bandgap (WBG) power semiconductor devices, such as SiC and GaN, have broadened the applications of motor drives in medium- and high-voltage regimes by pushing the limits of voltage, frequency, and power. These advantages of WBG inverters are being leveraged in aircraft and ship industries as they move towards next generation more- and all-electric designs. While the superiority of WBG technology in terms of faster switching, greater voltage breakdown strength, and short recovery time are known, its effect on the motor drive insulation is relatively unknown. This paper focuses on high-voltage high-frequency WBG inverters and analyses their effect on medium-voltage machine insulation. Specifically, analysis of dielectric stress and leakage current density is carried out on a 3-phase medium voltage motor's stator ground-wall insulation excited by a 2 level hex-bridge WBG inverter and a 3 level multilevel inverter in Ansys Maxwell and the results are presented.

Stable field oriented control of induction machines in the proximity of zero electrical frequency relies on the extraction of machine saliencies for rotor flux/positon acquisition. To obtain such saliency information, voltage step excitation methods can be used. They excite the machine with a voltage step caused by the inverter and calculate the resulting phase current derivative, which contains several terms including the superposition of saliency components. Multiple strategies have been used to calculate the current derivative, such as FFT, neural networks, or linear regression. However, they do not take into account the influence of a curvature of the current response. This paper proposes using a least-square quadratic regression to calculate machine saliency information. In this sense, the linear response of the phase current can be accurately isolated from the inherent curvature. It will be proved by experimental measurements that the different saliencies' components are observed in both the second order and also first order term of the quadratic regression function. A performance comparison between linear regression and quadratic regression will be shown in terms of saliency acquisition.

This paper presents a framework for the design and analysis of a light and low-cost axial flux permanent magnet motor which consists of dual permanent magnet rotors and a coreless Printed Circuit Board stator. Removal of the conventional laminated stator core significantly reduces core losses, decreases cogging and torque ripple and increases efficiency. The proposed design drastically eliminates magnetic forces between the rotor and the stator as well as the torque ripple, hence reduces the acoustic noise. A fully integrated variable frequency drive is proposed which uses high efficiency silicon carbide MOSFET inverter design. Using Printed Circuit Board stator enables simpler and faster manufacturing. An in-house analytical simulation has been used to model the motor design and evaluate the performance. The proposed design has been manufactured and was tested successfully. Finally, the test results are compared with the simulation results as well as finite element analysis.

Aerospace applications demand high Specific Power (SP) electrical machines to enable hybrid/electric propulsion. The targets for SP are 2-3X the state-of-the art. Therefore, the adoption of novel technologies including advanced and lightweight materials, additively manufactured coils, as well as innovative and tight integration of Thermal Management System (TMS) to the machine and its Power Electronic Unit (PEU) are effective design methods to boost the electric drivetrain SP. This paper aims to use the foregoing techniques and perform a study to examine the impact of key design parameters on the machine SP.

Among the multiphase solutions, multi-three-phase drives are experiencing significant industrial development since they can be configured as multiple three-phase units operating in parallel. The literature reports several control approaches to perform the torque regulation of multi-three-phase machines. Most of such solutions use the vector space decomposition (VSD) approach since it allows the control of a multi-three-phase machine using the conventional control schemes of three-phase drives, reducing the complexity of the control algorithm. However, this advantage is practically lost in the case of open-three-phase faults. Indeed, the post-fault operation of the VSD-based drive schemes requires the implementation of additional control modules, often specifically designed for the machine under consideration. Therefore, this paper aims at proposing a novel control approach that allows using any control scheme developed for three-phase motors to perform the torque regulation of a multi-three-phase machine both in healthy and faulty operation. In this way, the previously mentioned drawbacks of the VSD-based control schemes in dealing with the machine's faulty operation are avoided. Moreover, the simplicity of the control algorithm is always preserved regardless of the machine operating condition. The proposed solution has been experimentally validated through a 12-phase induction motor, rated 10 kW at 6000 r/min, which uses a quadruple-three-phase configuration of the stator winding.

In recent years, Vernier permanent magnet machines (VPMs) have gained much interest in academia. However, due to the large leakage flux, the power factor of Vernier machines is too low to be applied in real industry. In this paper, a novel split-tooth, concentrated-winding Vernier machine using ferrite magnets is proposed for high-torque, low-speed direct drive applications in home appliance industry. It uses consequent-pole magnets in the rotor, as well as additional assistant magnets in the stator teeth, in order to reduce the leakage flux and boost the torque density. A systematic way of reducing the torque ripple from 40% to 4% is proposed by carefully choosing the right combination of stator/rotor pole pair numbers. A comprehensive design optimization is conducted to achieve the optimal performance. The magnets in the stator are shaped on both corners to reduce the saturation level. The key findings during the optimization are described in detail. Finally the total number of turns per phase is carefully reduced to meet the torque, saturation, power factor and space requirements. The test results of a prototyped machine show that the proposed design can achieve 34% more torque and 20% less loss with a reasonable power factor of 0.63, compared with an optimized PM synchronous machine under the same volume. It is found that the significant torque boost is attributed to the multiple working harmonics of the air gap flux density.

This paper performs a comparative analysis of overmodulation methods for AC electric drives. Criteria for the analysis considers three aspects: output vs. commanded modulation index (i.e., linearity); harmonic content; and the number of commutations (i.e., switching losses). The analysis focuses on existing methods reported in the literature. Improvements for the existing methods will be proposed as a result of the analysis. The analysis is experimentally validated on a three-phase three-level Neutral-Point-Clamped (NPC) inverter.

It is commonly believed that if a motor surpasses the infant failure state trouble free, it will probably provide several years of reliable service. Traditional installation services unfortunately frequently do not identify and correct common causes of such infant failures, resulting in costly unplanned downtime shortly after a plant start-up. This paper proposes an approach to motor commissioning that aims to identify infant failure even before the plant is returned to service, thereby avoiding these costly productions losses, and providing opportunity for real time plant improvements and optimization.

Consequent pole (CP) permanent magnet (PM) machines have attracted considerable interest as a means of reducing machine cost through a marked reduction in the volume of permanent magnet required to meet a particular torque specification. However, the presence of a large torque ripple that can result from the CPPM structure can hinder their adoption in some applications, especially for the dominant third order torque ripple. Although several design-specific modifications have been proposed to ameliorate torque ripple, arguably the generalized principles underpinning this behavior have not been fully established. In this paper, it will be illustrated that an aggregation of the fluctuations in inductance, back EMF and cogging torque contributes to increased torque ripple. Meanwhile, an asymmetric pole shaping method is proposed to reduce the torque ripple, taking the dominant third order torque ripple as example. Simulated results of the 12-slot/8-pole prototypes show that compared to symmetrical pole shaping model and the plain pole model, the proposed asymmetric shaping method is effective in reducing torque ripple.
