Abstract
The invention relates to a primary magnetic conduction structure of a linear motor. The primary magnetic conduction structure comprises a magnetic conduction body, the magnetic conduction body is combined by a plurality of magnetic conduction ring bodies arranged in an array, an outer ring of each magnetic conduction ring body is adapted to the inner wall of a motor yoke, an inner ring of the magnetic conduction ring body is provided with ring holes for a motor secondary to penetrate through, and the side part of each magnetic conduction ring body is provided with an ring slot for arranging a primary coil. Because the magnetic conduction body combined by the plurality of magnetic conduction ring bodies arranged in an array and the structural style that the cake-type primary coils are arranged on the side part of the magnetic conduction ring bodies are adopted, the difficult problem of large pulse of alveolar caused by increased effective air gaps of traditional linear motors is solved, and effective stress of the motor is increased. In addition, the invention also has the advantages of simple manufacturing process and strong globality.
Description
Technical field
The present invention relates to the elementary magnetic conductor structure of a kind of motor, particularly a kind of linear electric motors.
Background technology
The elementary magnetic conductor of traditional form linear electric motors adopts two kinds of structures usually, the one, adopt shaft section silicon steel plate stacking structure, as shown in Figure 1, the I-shaped silicon steel sheet stator structure of another kind of employing, as shown in Figure 2, former structure can only be made the open slot form usually, can increase the motor effective air gap like this, produces bigger teeth groove pulsation, have influence on the stability of exerting oneself, and that the latter adopts is a kind of with the folded riveting of I-steel, and its technology manufacturing process is extremely complicated, and manufacturing cost is higher.
Summary of the invention
Technical problem to be solved by this invention is, at the problem of above-mentioned existence, provides a kind of and exerts oneself in the stability the elementary magnetic conductor structure of the linear electric motors of its more reasonable structural design, process optimization can effectively improving motor.
Technical scheme of the present invention is: a kind of elementary magnetic conduction structure of linear electric motors, comprise the magnetic conduction body, described magnetic conduction body is combined by a plurality of magnetic conduction ring bodies that are arranged in array, the outer shroud of described each magnetic conduction ring body and motor yoke inwall are suitable, be equipped with the secondary annular distance that runs through of power supply machine in the described magnetic conduction ring body, be provided with the annular groove of confession primary coil arrangement at the sidepiece of each magnetic conduction ring body.
Further: the above-mentioned annular groove that is arranged at each magnetic guiding loop side portion is that both sides are provided with or one-sided setting.
Further: the above-mentioned annular groove that is arranged at each magnetic guiding loop side portion is the symmetry or the asymmetric setting of both sides.
Further: the making that is formed in one of above-mentioned magnetic conduction ring body.
The present invention is owing to adopted the magnetic conduction body of being made up of a plurality of magnetic conduction ring bodies of array arrangement, and cake formula primary coil is arranged at the version of magnetic guiding loop side portion, solve the traditional line electric motor primary and increased a difficult problem that produces than the canine tooth slot ripple because of effective air gap, increased the motor effective force, in addition, it is simple that the present invention also has manufacture craft, the advantage that globality is strong.
