Special Issue Information

Dear Colleagues,

Electric machines play an important role in modern civilization with increasing applications in the electrification industry (EVs), aerospace, renewable energy systems (such as wind turbines), robotics, automation, and appliances. Each application has specific needs, with the power density, efficiency, fault tolerance, and reliability being among top features sought across different applications. To respond to the increasing needs of electric machines, research on the design, modelling, control, and operation of machines has increased in the past decade. Magnetic design, thermal analyses, new control techniques, and modelling approaches are being studied in different corners of academia and industry.

We have organized this Special Issue to cover all aspects of electric machines, including but not limited to:

  • Design, modelling, control, and operation of electric machines covering all types including induction machines, permanent magnet machines, switch reluctance machines, hybrid machines, and multiphase machines.
  • A wide range of applications, including renewable energy systems (wind turbines), power systems (synchronous generators), hybrid- and all-electric aircrafts, robotics and automation, and appliances.
  • Studies of electromagnetic, thermal, and mechanical aspects of electric machines as well as packaging and manufacturing.

We are seeking both original research as well as review papers.

Permanent magnet flux harmonics in Permanent Magnet Synchronous Motors (PMSMs) can cause torque ripple. Traditional torque ripple suppression methods based on analytical models are highly dependent on the accuracy of motor parameters, while existing flux harmonic identification techniques often suffer from limited precision, compromising the effectiveness of ripple suppression. This paper proposes an online flux harmonic identification method that considers the dead-time effect of inverters. A dead-time compensation algorithm is introduced to effectively mitigate current harmonics induced by inverter dead-time. The current harmonic signals are extracted using a multi-synchronous rotating coordinate system. A harmonic controller is employed to suppress current harmonics, and its output voltage is used to identify the permanent magnet flux harmonics, from which a flux harmonic lookup table is constructed. Based on the identified flux harmonics, the torque ripple suppression strategy using analytical methods is further optimized. Experimental results validate the effectiveness of the proposed method in improving flux harmonic identification accuracy and reducing torque ripple. Full article
