Abstract
Permanent magnet motors, owing to their high efficiency and energy-saving advantages, have been widely applied across various fields. However, the complexity of their magnetic fields poses significant challenges for performance optimization. This study aims to conduct an in-depth analysis of the magnetic field characteristics of a novel permanent magnet motor and explore effective control techniques to enhance motor performance. A magnetic field model of the new permanent magnet motor was established based on the finite element method, and different parameters were altered to simulate the operating conditions of the motor, thereby accurately obtaining the distribution patterns of the magnetic field. Concurrently, intelligent algorithms were introduced to monitor and regulate the motor's magnetic field in real-time, achieving precise control over the magnetic field. The results indicate that the developed model can accurately reflect changes in the motor’s magnetic field, and the intelligent algorithms can effectively address magnetic field fluctuations during motor operation, ensuring stable and efficient operation under varying working conditions. The innovation lies in the integration of the finite element method with intelligent algorithms to construct a new system for magnetic field analysis and control. This not only enhances the understanding of the magnetic fields in novel permanent magnet motors but also provides theoretical foundations and technical support for motor design and manufacturing, contributing to the development of more efficient and reliable permanent magnet motors.
