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

A Novel High-Performance Field-Weakening Control for Axial Flux-Switching Permanent-Magnet Motor
By combining the field-weakening control principle of a new axial flux-switching permanent-magnet motor (AFFSSPM) with the space vector pulse width modulation (SVPWM) and maximum torque per voltage (MTPV) control principle, a novel field-weakening control strategy for AFFSSPM is proposed in this paper. In the first stage of the field-weakening, the difference between the reference voltage updat...
