These integrated motor drives have many advantages compared to the traditional configuration of an electric motor with a wall-mounted drive or a direct grid connection, which is the current setting for most industrial electric motor drives. They offer a reduction in cost, end-user complexity, environmental electromagnetic interference issues, motor terminal overvoltage risk, higher volumetric power density, increase in system efficiency. Close integration of drive and motor poses certain design challenges: mechanically, electromagnetically and thermally. This paper presents a totally-enclosed fan-cooled integrated motor drive. The main objective is to investigate the integration concept and thermal behaviour. The power converter is integrated within the motor housing, protecting it from the external environment. The power electronics are cooled by the existing fan for the motor cooling. Loss models are introduced for the main components of the system: the rectifier, inverter, and motor. The thermal behaviour is studied using a combination of a thermal finite-element analysis and a lumped-parameter thermal network. This approach is applied to a 7.5 kW industrial induction motor-based prototype. The simulation and experimental results show the feasibility of the proposed concept and design approach.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"20 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.70204","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148616234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inevitably, such actuators require two position encoders, including a linear encoder and a rotary encoder. To achieve the reduction of system costs and the improvement of system reliability, a sensorless control strategy based on high-frequency square-wave signal injection is proposed to replace the rotary position encoder. By injecting high-frequency pulsating square-wave signals into the d-axis voltage, the estimated rotor position information can be decoupled from the αβ-axes voltage through a signal processing module. Simultaneously, to simplify the system structure and improve the control performance, a sliding-mode controller with an improved reaching law is utilised. The proposed sliding-mode controller is implemented based on the mathematical model of the MSM. The given q-axis current can be obtained from the given linear displacement through the mathematical model of the MSM; thus, the rotor speed closed-loop can be eliminated, and the traditional three-closed-loop structure can be simplified to a double-closed-loop structure. Moreover, the used reaching law can reduce chattering while ensuring the convergence speed. Consequently, the reliability and validity of the proposed method are verified through experimental results.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"20 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.70214","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148467145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these issues, this paper proposes an adaptive fusion sliding mode control in model predictive synchronization control (AFSMC-MPSC) method. First, a multi-IM model predictive synchronization control (MPSC) framework is constructed by integrating average deviation coupling control (ADCC) with model predictive torque control (MPTC). Then, an adaptive sliding mode observer (ASMO) is designed to estimate the load torque in real-time. Finally, based on the MPSC framework and the observed load torque, an adaptive fusion sliding mode controller (AFSMC) is developed to achieve collaborative optimization of tracking control and synchronization control. Simulation and experimental results demonstrate that the proposed AFSMC-MPSC method significantly improves the tracking and synchronization control performance and disturbance rejection capability of the system, and exhibits strong robustness against IM parameter mismatch.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"20 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.70206","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148381104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although existing position-sensorless diagnostic frameworks based on the rotor current vector modulus (CVM) are theoretically applicable to both rotating and stationary conditions, prior research has primarily established characteristic mechanisms, analytical relationships and threshold criteria specifically for rotating operation. Under standstill conditions, the DC components of the three-phase rotor currents do not contribute to stator electrical signals due to the absence of time-varying magnetic fields. Consequently, the DC components of the rotor current no longer contribute to the formation of stator-side signatures, rendering the CVM mathematical expressions and fault criteria established under rotating conditions no longer applicable. To address theoretical gaps under standstill conditions, this paper analyses fundamental differences in feature formation between rotating and stationary states using electromagnetic induction laws. An analytical standstill CVM model is derived within the CVM framework, and characteristic indicators with identification thresholds are established for static detection. Experimental results validate the derived standstill CVM analytical model and the proposed diagnostic indices, demonstrating that the method can accurately and robustly identify dual-diode open-circuit faults in the rotating diode rectifier under standstill conditions.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"20 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.70197","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148324203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a tailored hybrid physics–data surrogate model for steady-state temperature fields of oil-immersed transformers that deeply integrates Proper Orthogonal Decomposition (POD) with a specifically modified neural network architecture. First, a full-order model of the oil-immersed transformer is built, and temperature-field simulations are performed under various operating conditions. Second, Proper Orthogonal Decomposition (POD) is applied to extract characteristic modes from the simulated temperature-field snapshots, transforming the nonlinear temperature field into a linear combination of modes and modal coefficients. Finally, a Gaussian-activated fully connected neural network with local approximation capability is constructed, and a physics-informed loss function embedding POD modal importance is designed to approximate the nonlinear mapping between transformer operating parameters and modal coefficients, thereby completing the surrogate model construction. For the temperature-field solution under a given condition, the field can be rapidly reconstructed simply by linearly weighting the modes with modal coefficients predicted by the surrogate model. Validation shows that the proposed surrogate model can compute a single steady-state temperature-field distribution within 0.0129 s, and the maximum computation errors for global temperature and hotspot temperature do not exceed 3.5%, with the numerical results further validated by optical fibre temperature measurement experiments, meeting the requirement for real-time temperature-field perception in on-site operation and maintenance.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"20 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2026-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.70196","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148237808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To support this transition, the US Department of Energy (DOE) has established ambitious targets of $7/kW cost and 12 kW/L power density for the electric drivetrains. This paper attempts to meet these targets by proposing high-speed permanent magnet assisted synchronous reluctance machine (PMASynRM) topologies enabled by hybrid magnet strategies, combining rare-earth (RE) magnets with low-cost, RE-free alternatives. Modified 2-layer and 3-layer U-shaped rotor configurations, featuring structural reinforcements to withstand high mechanical stress at elevated speeds, are developed. A multi-objective design optimisation framework is employed to optimise the rotor design, targeting reductions in RE magnet volume, magnet demagnetisation risk and torque ripple while achieving the desired electromagnetic performance. A comprehensive analysis of the optimised rotor designs, compared against a 16,000 rpm, 800 V baseline IPM motor, shows over 70% RE reduction, demagnetisation risk below 3.5% and torque ripple under 10%. Detailed analyses of performance trends across various magnet combinations and rotor configurations highlight the viability of hybrid magnet PMASynRM designs as cost-effective, robust and energy-efficient solutions for next-generation EVs.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"20 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.70183","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148167027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
