Abstract
The utility model discloses a double-stator linear oscillation motor. The motor comprises two concentric stator cores which are formed through laminating silicon steel sheets along an axial direction. An interval which is used for accommodating a stator winding coil is arranged between the two stator cores. The stator cores are fixed with an engine base through a pressing plate. A rotor is a whole iron core which is formed through laminating a rotor punching sheet along an axial direction. N-S alternative and radial magnetizing permanent magnets are uniformly fixed on an outer circumference of a rotor core. Each permanent magnet corresponds to a stator core tooth. The rotor core is fixed with a linear shaft. Two ends of the motor are provided with linear bearings used for maintaining a constant air gap. The linear bearings are fixedly connected to a chassis end cover. The motor of the utility model adopts a counter magnetic flux motor working principle and iron core lamination is simple. A magnetic resistance force is approximate to zero and a good force characteristic is possessed. There are few parts. Assembling is convenient and cost is low.

Background technology
Linear vibration motor divides transverse magnetic general formula and non-transverse magnetic general formula.Non-transverse magnetic flux linear vibration motor main magnetic circuit is parallel to the direction of motion, and silicon steel sheet is arranged along the direction of motion, when motor is round tube shape structure, and silicon steel sheet closed assembly difficulty; Transverse magnetic flux linear vibration motor magnetic circuit is perpendicular to the direction of motion, and the cutting of silicon steel sheet, closed assembly are identical with common electric rotating machine, and easy to process, cost is lower.
Linear vibration motor oscillating component can be divided into coil, permanent magnet and iron core.Coil vibrational structure wiring place frangibility, should not be applied to high speed situation; In permanent magnet vibrational structure, permanent magnet support need adopt non-magnetic electric conducting material, and mechanical strength and resistance to shock require high, and machining is difficult, cost is higher; Core vibration structure is without permanent magnet support, the feature such as have processing, simple installation, simple in structure, Mechanical Reliability is high, cost is low.
Existing structure mainly comprises the good conventional moving-magnetic linear vibration motor of force characteristic and has the moving-iron type transverse magnetic flux linear vibration motor of permanent magnet magnetic resistance, and for the advantages of above-mentioned two kinds of structures is got up, so this case is arisen at the historic moment.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of linear oscillatory motor with two divided stators with two stator cores is provided, and this motor reluctance force is approximately zero, has the advantages such as good force characteristic, cost are low, practical.
The utility model technical scheme adopting of dealing with problems is:
A kind of linear oscillatory motor with two divided stators, it comprises two concentric stator iron cores that are overrided to form vertically by silicon steel sheet, between two stator cores, there is one section in order to hold the interval of stator winding coil, stator core is fixed by pressing plate and support, rotor is the iron core that a monoblock is axially overrided to form by rotor punching, even fix N-the S of rotor core excircle replaces the permanent magnet of radial magnetizing, every permanent magnet is corresponding with stator iron core tooth, rotor core and linear axis are fixed, motor two ends are provided with to maintain the constant linear bearing of air gap, this linear bearing is fixed on shell end cover.
The beneficial effects of the utility model are: adopt counter magnetic flux machine operation principle, iron core laminated is simple; Reluctance force is approximately zero, has good force characteristic; Part is few, easy to assembly, cost is low.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the utility model provides a kind of linear oscillatory motor with two divided stators, it comprises two concentric stator iron cores 3 that are overrided to form vertically by silicon steel sheet, between two stator cores 3, there is one section in order to hold the interval of stator winding coil, stator core 3 is fixing with support 2 by pressing plate 4, rotor 8 is the iron core that a monoblock is axially overrided to form by rotor punching, even fix N-the S of rotor 8 iron core excircle replaces the permanent magnet 1 of radial magnetizing, every permanent magnet 1 is corresponding with stator core 3 teeth, rotor 8 iron cores and linear axis 7 are fixing, motor two ends are provided with to maintain the constant linear bearing of air gap 6, this linear bearing 6 is fixed in shell end cover 5.When work, rotor 8 iron cores under the effect of spring and electromagnetic force together with linear axis double vibrations.The operation logic of motor can scold characteristic to be explained by the suction between magnetic pole.
The utility model adopts counter magnetic flux machine operation principle, and iron core laminated is simple; Reluctance force is approximately zero, has good force characteristic; Part is few, easy to assembly, cost is low.
