Abstract

The invention provides a transverse magnetic flux linear reluctance motor with an offset permanent magnet and belongs to the technical field of motors, and the transverse magnetic flux linear reluctance motor provided by the invention can be used for solving the problems that a permanent magnet is arranged at the secondary pole of the existing unilateral flat-plate-type linear permanent magnet synchronous motor, so that the motor cost is high and the reliability and safety are reduced. According to the five technical schemes provided by the invention, the motor comprises a primary pole and the secondary pole, wherein an air gap is reserved between the primary pole and the secondary pole; the primary pole comprises multiple phase armature units, each phase armature unit consists of an armature core, a phase unit armature winding and a phase unit permanent magnet; all coils on the armature core of each phase armature unit are connected in series to form one phase unit armature winding; and multiple phase unit armature windings are connected in series or in parallel to form a motor armature winding. According to the invention, the mode that the permanent magnet is arranged at the secondary pole of the existing linear permanent magnet synchronous motor is omitted, thus the motor cost is lowered, and the reliability and safety are improved.

Description

technical field [0001] The invention relates to a permanent magnet bias type transverse flux linear reluctance motor, which belongs to the technical field of motors. Background technique [0002] The structure of the existing unilateral flat linear permanent magnet synchronous motor is as follows: Figure 21 shown. The motor is composed of a primary and a secondary. The primary is mainly composed of an armature core and an armature winding, and the secondary is mainly composed of a permanent magnet and a magnetic yoke. The armature magnetic field generated by the energization of the armature winding interacts with the magnetic field of the secondary permanent magnet to generate electromagnetic force, which acts on the mover to drive the mover to move in a straight line. The advantages of this type of linear motor are simple control, good dynamic characteristics, high thrust linearity, simple primary structure, and convenient processing and manufacturing. However, the big d...
