Research on ropeless elevator driven by PMLSM
2016 Eleventh International Conference on Ecological Vehicles and Renewable Energies (EVER), 2016The permanent magnet linear synchronous machine (PMLSM) with long primary is a suitable candidate for ropeless elevator due to high force density and low thrust ripple. For the PMLSM with multi-segment long primary, it is impractical to excite all primary segments.
