Abstract
The utility model discloses a shaft-less motor which comprises a rotor, a stator and a casing. A stator punching piece is in a shape of a circular ring, the inner periphery of the stator circular ring is provided with a tooth groove for winding a wire resistor, and a through hole is arranged on a plane of the circular ring. A rotor punching piece is in a shape of a circular ring, and the inner periphery of the rotor circular ring is provided with a tooth groove for winding a wire resistor. Two axial ends of the rotor extend out of the stator to be fixedly connected with the casing through a bearing. The rotor of the shaft-less motor is in the shape of the circular ring, is directly connected with the casing through the bearing, rotates under the action of a magnetic field after powered on and forms fluid delivering power at the center of the rotor. By adopting the shaft-less motor, the two ends of the motor can be directly connected with a pipeline to form a fluid pump only by arranging a blade on the inner circumferential face of the rotor, other transmission connecting parts are not required, and materials and cost are saved.
Description
Technical field
The utility model is a kind of without spindle motor.
Background technology
Fluid pump mostly adopts blade wheel structure is installed on axle at present, directly or indirectly is with the moving axis rotation through motor, realizes carrying the fluid purpose.Such mechanism's Shortcomings part needs extra transmission connection piece, the waste material.
The utility model content
The purpose of this utility model is to provide a kind of without spindle motor, solves the problem of existing fluid pump waste of material.
The purpose of this utility model is come specific implementation by the following technical programs: a kind of without spindle motor, comprise rotor, stator and housing, this stator punching is made as circular, is provided with the teeth groove of wrap wire group on the inner rim of this annulus, and is provided with through hole on the plane of this annulus; This rotor punching is made as circular, establishes the teeth groove of wrap wire group on the neighboring of rotor annulus; This rotor axial two ends are stretched out stator and are fixedly connected with housing through bearing.
Further, this rotor punching is provided with through hole.
A kind of fluid pump comprises as mentioned above being provided with blade without spindle motor on the inner periphery of rotor.
Further, described blade arranges along the rotor axial multilayer.
The utility model is made as rotor without spindle motor circular, directly is connected with housing by bearing, and energising rotates by magnetic fields, will form the power of carrying fluid in rotor central authorities.Adopt the utility model without spindle motor, only need on the rotor inner peripheral surface, blade is set, motor two ends can directly be connected with pipeline, namely form fluid pump, need not other transmission connection piece, economical with materials and cost.
Description of drawings
The below is described in further detail the utility model according to drawings and embodiments.
Fig. 1 is the described structure chart without spindle motor of the utility model embodiment;
Fig. 2 is that the utility model is without the structural representation of spindle motor.
Embodiment
As shown in Figure 1, the utility model embodiment is described without spindle motor, comprises rotor 3, stator 2 and housing 1, this stator punching is made as circular, as shown in Figure 2, be provided with the teeth groove 21 of wrap wire group on the inner rim of this annulus, and be provided with through hole 22 on the plane of this annulus; This rotor punching is made as circular, establishes the teeth groove (corresponding with tooth slot structure in stator punching, in figure for drawing) of wrap wire group on the neighboring of rotor annulus; This rotor axial two ends are stretched out stator and are fixedly connected with housing 1 through bearing 31.
Selectively, establish through hole on rotor punching; It is to be convenient to heat radiation that through hole is set in two kinds of punchings.
Due to rotor 3 be formed by stacking for circular punching cylindric, add blade on its inner periphery, can play the effect of carrying fluid.Therefore, comprise above-mentioned fluid pump without spindle motor, only need on the inner periphery of rotor 3, blade to be set, can obtain carrying the kinetic pump of fluid, easy to connect with fluid line, saved other drive apparatus.
Claims (2)
1. one kind without spindle motor, comprises rotor, stator and housing, and it is characterized in that: this stator punching is made as circular, is provided with the teeth groove of wrap wire group on the inner rim of this annulus, and is provided with through hole on the plane of this annulus; This rotor punching is made as circular, establishes the teeth groove of wrap wire group on the neighboring of rotor annulus; This rotor axial two ends are stretched out stator and are fixedly connected with housing through bearing.
