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...

The rope-less elevator driven by Permanent Magnet Linear Synchronous Motor (PMLSM) is a new technology for high-rise buildings. In the practical operation, PMLSM inevitably encounters various kinds of turbulences which directly affect the rope-less elevator’s operation. The braking system is important for rope-less elevator safe and steady operation. Usually, the ordinary inspections are not ab...
