Optimal Design of a Double-Sided Permanent Magnet Linear Synchronous Motor for Ropeless Elevator System

Abstract:

The ropeless elevator driven by linear motor is expected to be a new solution to vertical transportation of skyscrapers and the deep underground mines. Due to high thrust force density, low force ripple and low cost etc., a double-sided permanent magnet linear synchronous motor (DPMLSM) with slotted iron core and multi-segment primary is proposed and designed. Based on the erected 2D finite element model, the structure is optimized in order to reduce the detent force. Moreover, the influence of manufacture error on force performance is also investigated. It is shown the proposed DPMLSM is suitable for the ropeless elevator.
