Special Issue Information

Dear Colleagues,

So far, climate change has been raising the main issues in the world. Most of the countries have pushed corresponding policies to accelerate and scale up action to realize universal access to clean, affordable energy by 2030 and net-zero emissions by 2050. In this case, it is significant to develop electric machines and drive technologies, which contain a series of characteristics in high-power density, high torque density, high tolerant capability, low cost, low torque ripples, and high dynamic response performance.

This Special Issue aims to offer a timely opportunity for academic researchers and industrial engineers to present, discuss, and exchange the latest results and findings of technologies on the electrical machine design, motor control algorithms, sensorless control, parameter identification, and motor drive topologies.

Topics of interest for publication include, but are not limited to:

  • Model predictive control in motor drives;
  • Digital motor control;
  • Design, modelling, and analysis of electrical machines;
  • New topologies of power electronics;
  • Fault-tolerant electric motor drive systems;
  • Condition monitoring and fault diagnosis;
  • Parameter identification and sensorless control;
  • Multi-phase motor control.

The Dual–Vector model predictive control (DV–MPC) method can improve the steady–state control performance of motor drives compared to using the single–vector method in one switching cycle. However, this performance enhancement generally increases the computational burden due to the exponential increase in the number of vector selections, lowering the system’s dynamic response. Alternatively, limiting the vector combinations will sacrifice system steady–state performance. To address this issue, this paper proposes an enhanced DV–MPC method that can determine the optimal vector combinations along with their duration time within minimized calculation times. Compared to the existing DV–MPC methods, the proposed enhanced technique can achieve excellent steady–state performance while maintaining a low computational burden. These benefits have been demonstrated in the results from a 2.5k rpm permanent magnet synchronous motor drive. Full article

The rotor loss of rare earth permanent magnet synchronous motor (PMSM) affects the efficiency and reliability of the motor and is an important research direction of rare earth permanent magnet synchronous motors. In this paper, the influence of rotational speed on the loss of the rotor core and the permanent magnet is analyzed through the analysis of the motor magnetic field and rotor loss calculation. Specifically, with the increase in rotational speed, the weak magnetic current increases, the amplitude of flux density change in the rotor core decreases, and the loss of the rotor core also decreases. The greater the influence of the harmonic current magnetic field on the outside of the rotor, the greater the loss. The core loss on the rotor is mainly distributed on the outside of the rotor. For further engineering applications, this paper analyzes the loss composition of three kinds of motors with different rotor structures and judges the optimal scheme based on the minimum loss. Finally, the correctness of this research is verified by comparing the experimental and simulation results of two kinds of motors with different rotor structures. The research content of this paper can provide a reference for the loss analysis and optimization and rotor structure selection of rare earth permanent magnet synchronous motor rotor design.
