Special Issue Information

Dear Colleagues,

In response to increasing efficiency requirements for electrical motors, the rotor hybridization of synchronous motors has emerged as a viable solution to both increase efficiency and fault tolerance. Due to rotor hybridization the motor torque is developed through more than one phenomenon. In this category, motors such as line-start synchronous motors develop torque, via induction in a squirrel cage or synchronously due to reluctance and/or permanent magnet flux, being highly recommended for the direct replacement of old induction motors. Motors such as permanent magnet assisted synchronous reluctance motors develop their synchronous torque due both the reluctance and permanent magnet flux, being more fault-tolerant in case of rotor faults.

This Special Issue aims to explore the fault tolerance in hybrid rotor synchronous motors through design, fault diagnosis and control. It targets increasing fault tolerance via new designs, evaluations of hybrid rotor synchronous motors in terms of transient and steady-state faulty operations and new fault-tolerant control strategies. The Special Issue covers the improvement of analytical and finite element models in performance prediction as well as the development of experimental setups in the measurement of the behavior of hybrid rotor synchronous motor drives under different faults such as stator faults, demagnetization, broken rotor bars, eccentricity, and power converter faults. It considers a wide range of hybrid rotor synchronous motors including line-start permanent-magnet synchronous motors (LSPMSMs), line-start synchronous-reluctance motors (SynRMs), permanent magnet-assisted synchronous reluctance motors (PMASynRMs), etc.

This Special Issue focuses on the following:

  • Analytical and finite element modeling as well as the optimization of more fault-tolerant hybrid rotor synchronous motors;
  • Transient and steady-state operation prediction and the measurement of faulty hybrid rotor synchronous motors;
  • The design and analysis of special types of hybrid rotor synchronous motors such as line-start permanent magnet-assisted synchronous reluctance motors, multi-phase hybrid rotor synchronous motors, etc.;
  • The fault analysis of hybrid rotor synchronous motors;
  • The thermal modeling of hybrid rotor synchronous motors, particularly under faulty conditions;
  • The condition monitoring of hybrid rotor synchronous motors;
  • The application of artificial intelligence in the performance parameter estimation, analysis, and design of hybrid rotor synchronous motors;
  • Solutions for variable speed capabilities as well as improved fault tolerance control solutions for hybrid rotor synchronous motors;
  • Studies comparing the efficiency, power factor, and reliability of hybrid rotor synchronous motors with those of other competitors such as permanent magnet synchronous motors or induction motors.
