This paper addresses the critical issue of torque ripple in Permanent Magnet Synchronous Motors (PMSM) employed in hermetic reciprocating compressors for refrigerators. Torque ripple, a phenomenon characterized by unwanted variations in motor torque during operation, can lead to performance inefficiencies, increased vibrations, and accelerated wear and tear. The study proposes a comprehensive optimization approach to minimize torque ripple in PMSM motors through a combination of advanced control strategies and design enhancements. The investigation begins with a thorough analysis of the torque ripple sources within the PMSM motor, considering factors such as cogging torque, magnetic saturation, and non-idealities in motor parameters. Subsequently, an innovative control algorithm is introduced, tailored to mitigate torque ripple by optimizing the current waveform. Additionally, modifications in motor design, such as pole shaping and material selection, are explored to further enhance performance and reduce torque fluctuations. This research contributes valuable insights into the torque ripple minimization of PMSM motors, offering practical solutions for enhancing the reliability and efficiency of hermetic reciprocating compressors in refrigeration systems. The findings presented in this paper have broad implications for the design and operation of refrigeration systems, emphasizing the importance of torque ripple optimization in achieving energy-efficient and durable motor-driven compressors.
