Abstract

The utility model discloses a novel plastic-sealed motor structure. The novel plastic-sealed motor structure comprises a plastic-sealed stator (1), a rotor assembly (2) and an end cover (3), wherein the rotor assembly (2) is arranged in the plastic-sealed stator (1); the end cover (3) is arranged at the end of the plastic-sealed stator (1); bosses (11) are bulged on the outer side of the end cover (3) and the end face of the plastic-sealed stator (1); and the outer lateral surface of the end cover (3) is closely pressed on the inner lateral surface of the plastic-sealed stator (1) below the bosses (11). The end cover is firmly connected with the plastic-sealed stator by increasing the contact area of the plastic-sealed stator and the end cover, the end cover is difficult to fall off, and the novel plastic-sealed motor structure is simple and compact and ensures the normal work of the motor.

Description

A kind of novel plastic packaging motor structure

Technical field:

The utility model relates to a kind of novel plastic packaging motor structure.

Background technology:

Traditional plastic packaging motor structure comprises plastic packaging stator, rotor assembly and end cap, and rotor assembly is installed in the plastic packaging stator; End cap is installed in the two ends of plastic packaging stator; The axial location of end cap leans on and fixes with the frictional force of plastic packaging stator inwall, because the end cap outside is little with plastic packaging stator inwall contact area, the frictional force between end cap and the plastic packaging stator is less; In machine operation, cause end cap to come off easily, influence the motor operate as normal.

Summary of the invention:

The purpose of the utility model provides a kind of novel plastic packaging motor structure, and big through increasing plastic packaging stator and end cap contact area, it is fastening that end cap is connected with plastic packaging stator, and the end cap difficult drop-off is simple in structure, compact, guarantees the motor operate as normal.

The purpose of the utility model is achieved through following technical proposals.

A kind of novel plastic packaging motor structure; Comprise plastic packaging stator, rotor assembly and end cap; Rotor assembly is installed in the plastic packaging stator; End cap is installed in the end of plastic packaging stator, on the outside of end cap, plastic packaging stator end face, protrudes boss, and the lateral surface of end cap is close on the medial surface of boss below plastic packaging stator.

Above-mentioned described boss is an annular boss or some boss spaced apart.

Above-mentionedly describedly on the inwall of the rotor assembly outside, plastic packaging stator, be provided with step, end cap is bearing on the step.

The utility model compared with prior art has following effect: 1) the utility model is through plastic packaging stator end face protrusion boss, increases the contact area, simple in structure, compact of end cap and casing, connect fastening, end cap difficult drop-off, assurance motor operate as normal; 2) on the inwall of the rotor assembly outside, plastic packaging stator, be provided with step, end cap is bearing on the step, reasonable in design, compactness.

Fig. 2 is the structural representation of the utility model.

Fig. 3 is the A-A partial sectional view of Fig. 2.

Fig. 4 is the B-B part enlarged drawing of Fig. 3.

Embodiment:

Below through specific embodiment and combine accompanying drawing that the utility model is described in further detail.

Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4; The utility model is a kind of novel plastic packaging motor structure; Comprise plastic packaging stator 1, rotor assembly 2 and end cap 3, rotor assembly 2 is installed in 1 li of plastic packaging stator, and end cap 3 is installed in the end of plastic packaging stator 1; Protrusion boss 11 on the outside of end cap 3, plastic packaging stator 1 end face, the lateral surface of end cap 3 is close on the medial surface of boss 11 below plastic packaging stators 1; Described boss 11 is an annular boss or some boss spaced apart; On the inwall of rotor assembly 2 outsides, plastic packaging stator 1, be provided with step 12, end cap 3 is bearing on the step 12.

The utility model is protrusion boss 11 on the outside of end cap 3, plastic packaging stator 1 end face, and it is big with end cap 3 contacts area to increase plastic packaging stator 1, and end cap 3 axially loadeds are increased, and is simple in structure, compact, connects fastening, end cap difficult drop-off, assurance motor operate as normal.
