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.

A simulation model of PMLSM based on physical platform
Proceedings of the 33rd Chinese Control Conference, 2014The model of permanent magnet linear synchronous motor (PMLSM) is complex, and the ready-made PMLSM block can not be found in Matlab during the process of simulation. A lot of simplified models are not compared with the physical object and can not reflect the actual well, so that a lot of advanced algorithms will not be used in the actual effectively ...
