Synchronous reluctance machines offer lower production costs, reduced temperature rises, and high efficiency, generating considerable interest across academic and industrial domains. Research prioritises enhancing machine performance under both normal and faulty operating conditions, targeting increased torque density, improved operational efficiency, and lower torque ripple. Approaches explored across the literature concentrate on four primary technical domains: optimal rotor design, the selection of magnetic steel grades, stator winding configurations, and fault tolerance control strategies. Examining these distinct areas helps clarify the current technical pathways available to mitigate inherent limitations such as torque ripple while maximising the efficiency and reliability advantages associated with reluctance-based electrical machine technologies.
Efficient electric motors are vital for reducing energy consumption and lowering manufacturing costs across modern industry. Synchronous reluctance machines provide an economical, energy-efficient alternative to conventional motor designs, but achieving widespread utility requires overcoming performance trade-offs such as torque ripple. Categorising improvements across hardware design and control strategies helps direct engineering efforts toward more dependable, high-performing electric drives.
The abstract highlights interest from industrial applications seeking cost savings, low operating temperatures, and higher efficiency. Industrial motor manufacturers and drive developers can apply these findings across machine design and fault-tolerant control. Because this work constitutes a review of existing scientific research across design and control methods, it reflects an early-stage to applied synthesis rather than an immediately deployable product.

Due to the significant advantages of cost savings, low temperature rises and high efficiency, synchronous reluctance machines (SynRMs) have attracted growing interest from academia to industrial applications. Numerous articles have been published to obtain a SynRM with improved performance (i.e., a high torque density and efficiency and a lower torque ripple) using different focusing points at healthy and faulty conditions such as rotor design, magnetic steel grade, stator winding, and fault tolerance control (FTC) strategy. Hence, this article reviews the scientific researches about SynRMs aiming to improve their performance. These scientific researches can be categorized into four sections: 1) optimal rotor design; 2) magnetic steel grade; 3) winding configurations; and 4) FTC strategies.
