Performance analysis and optimization of permanent magnet flux switched linear motor for ropeless elevator

Permanent magnet linear synchronous motor (PMLSM) is one of the ideal driving sources ropeless elevators. However, such motors, whether moving magnetic or coil, will produce problem excessive cost under long travel. The permanent flux switched (PMFSLM) with magnets (PMs) and copper coils on mover side greatly reduces cost. A U-type PMFSLM proposed in paper. First, a investigated, quantitatively comparing PMLSM for elevator system. Second, aiming at leakage top PMFSLM, PM (UPM) structure presented. electromagnetic performance UPM-FSLM have been compared summarised. comparison results show that solves defect leakage, increases thrust by 4.34%, ripple 28.10%, has better than PMFSLM. Afterwards, passenger capacity are simulated calculated feasibility analysed. Finally, prototype built measured.
