Abstract

The invention provides a permanent magnetic straight line synchronous motor capable of turning, a curve system and a rail car, and belongs to the technical field of rail physical distribution delivery. The permanent magnetic straight line synchronous motor capable of turning and a curve system comprise a rail and a permanent magnetic straight line synchronous motor, wherein the rail comprises a straight line rail and a turning rail; the permanent magnetic straight line synchronous motor comprises a primary level and a secondary level; the primary level comprises a plurality of primary units (1); the secondary level is formed by the connection of m sections of secondary units (2) through rotary pairs (5); each secondary unit (2) comprises a secondary iron core and permanent magnets arranged on the secondary unit in a manner that N and S poles are alternated. According to the invention, the problems that the permanent magnetic straight line synchronous motor cannot turn and cannot be driven in a relay manner when used in the field of long distance material delivery can be solved.

Description

technical field [0001] The invention relates to a turnable permanent magnet linear synchronous motor, a curve system and a rail car, and designs a matching rail car, which can be applied to the technical field of rail logistics transportation. Background technique [0002] Permanent Magnet Linear Synchronous Motor PMLSM (Permanent Magnet Linear Synchronous Motor) uses high-energy permanent magnets (such as permanent magnets made of NdFeB materials), which have the characteristics of high thrust, small electrical time constant, and fast response. It can directly convert electrical energy into linear motion without any intermediate conversion mechanism. It has the advantages of simple structure, non-contact operation, low noise, high speed and precision, simple maintenance, and high reliability. At present, various linear motors have been used in electronic manufacturing equipment. (such as high-speed placement machines, micro-encapsulation platforms), high-speed and high-prec...
