Analysis Review of Electromagnetic Fields in System Long Stator Linear Synchronous Motor for Improving Maglev Speed

Abstrak

This research presents an in-depth literature review regarding the role and characteristics of electromagnetic fields in the Long Stator Linear Synchronous Motor (LS-LSM) system to support the improvement of transportation maglev operational speed. The review emphasizes how magnetic flux behavior, field uniformity, and electromagnetic synchronization influence propulsion efficiency and dynamic stability in high-speed maglev operations. As the primary propulsion unit, the LS-LSM operates by synchronizing the moving magnetic field generated along the stator with the magnetic elements on the train, thereby producing a stable and continuous propulsion force. The findings indicate that the quality of the electromagnetic field, evaluated through flux density, waveform purity, and harmonic distortion reduction, significantly affects levitation stability, propulsion smoothness, and energy conversion efficiency. Electromagnetic field optimization can reduce power losses, minimize propulsion force fluctuations, and maintain propulsion performance at high speeds. This review also identifies potential technological developments, including the use of advanced magnetic materials, improved stator designs, and intelligent control strategies capable of regulating the electromagnetic field in real time. These insights support the design of propulsion systems that are more efficient, stable, and responsive. The research concludes that improving the quality of the electromagnetic field in LS-LSM systems is a key factor in achieving higher maglev speeds, better operational stability, and greater reliability for next-generation transportation systems.Top of Form
