The paper presents a new method to estimate the surface losses caused by the non-sinusoidal spatial distribution of the magnetic field, moving over the surface of laminated rotor cores. The rotating magnetic field present in the air gap of ac electrical machines causes additional losses, which are very important during motor design, in particular for high-speed applications. A simplified - but still consistent in its nature - finite element method model has been developed to simulate the mechanism of the surface loss generation. The obtained results are critically discussed and compared with those reported in other research works.

Consequent pole (CP) permanent magnet (PM) machines offer scope to reduce the quantity of PM material and hence cost compared to more conventional PM machine topologies of the same rating. In this type of machine, the rotor pole arc is usually optimized to realize the largest output torque with pole shaping methods used to reduce torque ripple. However, such approaches tend to be limited by constraints imposed on the pole shapes. It is common practice to adopt similar PM and iron pole shapes, an approach which does not fully account for the different characteristics of PM and iron poles in CPPM machines, often leading to large even order harmonics in the airgap flux density. This paper proposes a shaping method with a variable rotor profile and pole arc span being established by means of optimization by a Genetic Algorithm. It is demonstrated that for a fixed quantity of PM material, different PM and iron pole shapes in combination with optimal PM and iron pole arc spans are essential for ensuring both maximum output torque and lower torque ripple when due account is taken of flux leakage. It also demonstrates that since the flux density in the region under a PM pole is governed by the magnetic potential produced by magnets while it is governed by magnetic reluctance under iron pole, different PM pole and iron pole shapes are necessary to reduce the even order harmonics in a CPPM machine and consequently to reduce torque ripple. The performances of optimized and more conventional CP machines are compared by finite element method on 12-slot/8-pole prototype motors.

Since permanent magnet synchronous motors (PMSMs) have advantages of efficiency and energy density, they are now widely being used for many purposes. Based on such increased use, they require improved efficiency, lower acoustic noise, and fewer vibrations. However, such fabrication tolerances as eccentricity and roundness degradation generate a magnetic unbalance in the magnetic gap and cause low-order harmonics of electromagnetic force and cogging torque that create acoustic noise and vibrations. Since multi-three-phase PMSMs can individually control the phase current of each group, reducing the magnetic unbalance is possible in the magnetic gap. To control the phase current of each group, magnetic unbalance must be detected. In this study, we focus on static eccentricity as a representative fabrication tolerance and propose a method to detect it using the third-order harmonic component of no-load line-line voltages, which is easily measurable in practical production processes. We demonstrate our method that estimates the amount and direction of static eccentricity with a theoretical approach and confirm its detection by finite element analysis (FEA).

In this paper, an online rotor position error correction method is proposed to eliminate the impact of parameter mismatch in sensorless control of dual three-phase (DTP) permanent magnet synchronous machines (PMSMs). The position error production mechanism is firstly derived, i.e., the error changes with the trend of current variation when there is a parameter mismatch. Based on this mechanism, by injecting sinusoidal current signals into both sets of three-phase windings, the presence of parameter mismatch and its level can be revealed through the corresponding sinusoidal responses from the estimated speed of sensorless observers. Since the amplitudes of rotor position error responses decrease as the parameter mismatch level reduces, with the help of the least mean square (LMS) algorithm, the parameters can be adaptively adjusted to the actual values, and the position error can be thus corrected. Moreover, through a simple technique and with the extra freedom of DTP machines, the detrimental effects because of current signal injection can be eliminated. The proposed method has been validated through simulation and experimental results.

In this work, a comparison between different brushless harmonic-excited wound-rotor synchronous machines is performed. The general idea of all topologies is the elimination of the slip rings and auxiliary windings by using the already existing stator and rotor winding for field excitation. This is achieved by injecting a harmonic airgap field with the help of power electronics. This harmonic field does not interact with the fundamental field, it just transfers the excitation power across the airgap. Alternative methods with varying number of phases, different pole-pair combinations, and winding layouts are covered and compared with a detailed Finite-Element-parameterized model. Parasitic effects due to saturation and coupling between the harmonic and main windings are considered.

Conventional Variable Reluctance (VR) resolvers require a complicated winding arrangement, and extra circuit component to demodulate high frequency induced voltage. This paper presents an innovative design solution to reduce the structural complexity of the resolver and improve the functionality of the controller unit. The proposed design simplifies the winding arrangement and eliminates the necessity of the demodulation signal processing circuit. In addition, the conventional PI controller is being replaced by the adaptive PI controller to automatically adjust the controller setting for different operational speeds. The performance of the proposed design is compared against the conventional VR resolver via Finite Element.

In this paper, a cost-effective four-leg inverter is proposed to independently control two three-phase permanent magnet synchronous motors (PMSM). In this topology, one of the phases of the three-phase PMSM is connected to the midpoint of the dc-link. The mathematical model of the four-leg drive is derived. In addition, the discrete model of the three-phase PMSM and capacitor voltages are obtained. The model predictive control for these motors is developed to control the PMSMs' speeds and voltage of dc-link capacitors and therefore improve the performance of the four-leg inverter. Simulation results are presented to validate the effectiveness of the proposed drive and control method.

The power density of electric motors for aircraft propulsion is maximized by optimizing the electrical and magnetic loading and operating at high speed. Maximizing the current density without constraining the speed (and, consequently, the frequency) and the working magnetic field would significantly improve the power density. However, this would increase resistive losses in the winding which need to be removed through heat conduction. Thus, improving the winding thermal conductivity is an essential piece of motor design, especially for slot-less machines. This paper focuses on the comprehensive process of theoretically and experimentally evaluating the equivalent thermal conductivity for Litz-wire configured windings made with a single turn and multiple turns for slot-less permanent magnet synchronous machines. A detailed experimental procedure for various winding designs will be introduced, discussed, and confirmed through a bench test with an assessment of the results. The evaluation and comparison of windings formed with various resins are also performed to demonstrate potential thermal conductivity improvement through appropriate winding design.

This work strives to apply the in-slot direct cooling technique in electric machines and optimize the cooling design to improve the machine performance in both cooling and electromagnetic (EM) aspects. The in-slot cooling directly removes the heat from the heating source, but requires extra spaces in the slots that possibly reduce the electromagnetic performance of the machine. It needs an overall evaluation considering both EM and thermal performances to achieve an optimal machine design for in-slot cooling systems. This work utilizes a thermal-network based numerical modeling approach combined with finite element (FE) EM simulations to evaluate the proposed in-slot cooling scheme and compares it with a drip-cooled machine product from multiple aspects, such as torque output, temperature, efficiency and pump power. The thermal network model was verified with thermal FE simulations and is capable of predicting the transient temperature of the machine system. The temperature distribution and corresponding power losses of the electric machines with in-slot cooling designs were calculated on various machine operating points. The final efficiency of the in-slot cooled machine was compared with the drip-cooled machine. Then, an in-slot cooling design was chosen based on the simulation results and comparison for prototyping. Finally, a 3D printed prototype of a partial machine with in-slot cooling channels was designed and constructed to check the manufacturability of the proposed cooling design.

Modeling faulty behavior of systems has benefits in diagnosis and control. In this paper a data-driven method, dynamic mode decomposition with control (DMDc), is employed for modeling an inverter-fed induction machine. Results are shown and compared for two scenarios: A step input change and an inverter fault. For both cases, the algorithm can correctly predict behavior of the system. The advantage of this model is its independence from the system parameters. The results show promise for data-drivenfault diagnostics and system modeling.
