Special Issue Information

Dear Colleagues,

This Special Issue invites advanced research on motor condition monitoring, focusing on the integration of artificial intelligence (AI), parameter identification, and novel sensor technologies. With the rapid evolution of Industry 4.0 and smart manufacturing, ensuring the reliability, efficiency, and safety of electric motors has become critical across industries such as industrial automation, robotics, electric vehicles, and renewable energy systems. This Special Issue aims to explore innovative methodologies that bridge the gap between theoretical advancements and practical applications, addressing challenges such as real-time data processing, fault prediction, and adaptive control.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • AI-driven anomaly detection and fault diagnosis: Leveraging machine learning (e.g., deep neural networks and reinforcement learning) and data fusion techniques to identify motor faults, such as bearing wear, rotor imbalance, and insulation degradation.
  • Dynamic parameter identification: Advanced algorithms for the real-time estimation of motor parameters (e.g., resistance, inductance, and inertia) under varying operational conditions. Examples include adaptive estimation frameworks and hybrid models combining physics-based and data-driven approaches.
  • Smart sensor technologies: Development of embedded sensors (e.g., AI-integrated current/voltage sensors and MEMS-based vibration sensors) and wireless sensor networks for high-precision, low-latency data acquisition.
  • Digital twin applications: Virtual modeling of motor systems for predictive maintenance, integrating real-time sensor data with physics-based simulations to optimize performance and longevity.
  • Multimodal data fusion and collaborative analytics: AI-driven integration of heterogeneous data (current, vibration, and temperature) for real-time monitoring, fault prediction, and enhanced reliability in motor systems.

I/we look forward to receiving your contributions.

Traditional motor temperature rise testing generally uses temperature sensors. To solve problems such as sensor detachment, aging, and space occupation, this study takes a three-phase asynchronous motor as an example to propose a method for building a temperature rise monitoring model driven by a multi-physics field model based on the digital twin framework of power equipment. A twin monitoring model with defined input–output parameters is constructed to solve the problems of measurement inconvenience in traditional methods. Firstly, the losses of the iron core and the winding copper in the motor were obtained through electromagnetic field simulation. Secondly, the temperature distribution of the motor stator was obtained based on the bidirectional coupling characteristics of the magnetic and thermal fields. Subsequently, a temperature field reduced-order model based on the proper orthogonal decomposition method was built in Twin Builder, achieving fast calculation of the motor stator temperature. Finally, using the YE3-80M1-4 motor as the experimental subject, the model’s output results were compared with and validated against the experimental results. The results indicate that the simulation time of the reduced-order model is 2.1 s, and the relative error compared with the test values is within 5%, which confirms the practical applicability of the proposed method.
