The 2D electromagnetic field and performance analytical expressions are given in the detailed field circuits method. A line-line voltage equivalent circuit is developed to analyze the static performance of PMLSM. Special attention is paid to the structure, the influence of the longitudinal end effect, and the unbalance of the current. It provides an accurate method for analyzing PMLSM. It can also be used for other types of LSM. Key words: permanent magnet linear synchronous motor; PMLSM; static performance; linear motor 1 Introduction In the early 1990s, theoretical and experimental research on "vertical transportation systems driven by linear synchronous motors" began worldwide. It will be a major transformation of traditional rotating electric motor-driven vertical transportation systems. Due to its significant theoretical research value and very attractive application prospects, it has received increasing attention. It mainly includes applications in two areas: high-rise building elevators and mine hoisting systems. Its power source adopts a permanent magnet linear synchronous motor (PMLSM), which may be the only and best solution at present, but PMISM Many theoretical and technical problems still need to be solved, and its theoretical research is not yet complete. Its analytical research currently focuses on one-dimensional steady-state aspects, mainly including the magnetic circuit method and the equivalent circuit method. It generally idealizes the motor, taking one pole pitch as the solution region, and equating the windings and permanent magnets to sinusoidal current layers, neglecting the effects of core interruption, edge effects, compensating windings, end slot filling, and actual imbalance of the three-phase windings. Therefore, it basically follows the analytical methods of rotating electrical machines.
