Abstract
The utility model discloses a novel permanent magnet switch flux-linkage linear motor comprising a stator and a mover. The mover is a flat plate composed of a plurality of modules and magnetic resistance pieces which are arranged at intervals, wherein each module is composed of two inverted U-shaped iron cores, a permanent magnet clamped between the two iron cores and a three-phase armature winding wound on the two iron cores, N poles and S poles of the permanent magnets of adjacent modules are arranged alternately, and the upper part of the mover is fixed on a straight strip-shaped casing. The novel permanent magnet switch flux-linkage linear motor designed in the utility model has the beneficial effects that: as the upper part of the mover is fixed on the straight strip-shaped casing, the top parts of the components of the mover such as the iron cores, the permanent magnets and the magnetic resistance pieces are fixed together, and connection is firmer; and the casing plays a protective role at the outer side, which makes the structure of the linear motor firmer and more durable and effectively prolongs the service life of the linear motor.
