Embodiment 1

[0031] like Figure 1-5 As shown, the plastic-encapsulated coil motor provided by Embodiment 1 of the present invention includes a plastic-enclosed stator assembly 100, a rotor assembly 200 installed inside the plastic-enclosed stator assembly 100 and rotated with the plastic-enclosed stator assembly 100, and a plastic-enclosed The outer end cover 300 at one axial end of the stator assembly 100 and the outer bearing 400 disposed inside the outer end cover 300, the plastic-encapsulated stator assembly 100 includes a stator assembly 1, a mounting bracket 2 arranged below the stator assembly 1, and a plastic sealing molded on the stator assembly 100. Outside the component 1, the stator component 1 and the mounting bracket 2 are injection-molded into an integral plastic casing 3. The plastic casing 3 is specifically injection-molded by BMC plastic sealing material (bulk molding compound). The mounting bracket 2 includes a The plastic-encapsulated connecting portion 21 and the moun...

Embodiment 2

[0045] like Image 6 As shown, the main difference between the plastic coil motor provided in this embodiment and the first embodiment is that the shape of the mounting bracket 2 is different. Specifically, the same as the first embodiment, in this embodiment, the mounting bracket 2 is also The integrally formed bent plate also includes a middle transverse plate body 211, two vertically folded plate bodies 212 that are bent and extended downward along the two ends of the middle transverse plate body 211, and two vertically folded plate bodies 212 that are respectively extended along the bottom of the two vertically folded plate bodies 212. The horizontally folded plate body 22 extending laterally away from the middle horizontal plate body 211, the middle horizontal plate body 211 and the two vertically folded plate bodies 212 also constitute the plastic sealing connection part 21, and the two horizontally folded plate bodies 22 are also the installation part 22, The length of ...

Embodiment 3

[0049] like Figure 7 As shown, the main difference between the plastic coil motor provided in this embodiment and the first embodiment is that the shape of the mounting bracket 2 is different. Specifically, in this embodiment, the mounting bracket 2 is not a bent plate, but integrally formed For the flat plate, the middle part of the flat plate is a plastic sealing connection part 21 , and the two ends of the flat plate are installation parts 22 . In this embodiment, the installation bracket 2 is set as a flat plate, which can also realize the separate connection of the installation bracket 2 and the plastic casing 3 and the installation structure of the application. Compared with Embodiment 1, the combination reliability of the mounting bracket 2 and the plastic casing 3 in this embodiment is slightly worse, but the mounting bracket 2 in this embodiment has a simple structure and is easier to manufacture and shape.

[0050] Preferably, the middle part of the plate is provided...

Abstract

The invention is suitable for the field of a motor and discloses a plastic package coil motor which comprises a plastic package stator assembly. The plastic package stator assembly comprises a stator assembly, an installation support arranged under the stator assembly and a plastic package housing which is moulded outside the stator assembly and enables the stator assembly to be connected with the installation support into an integrated body in an injection molding manner. The installation support comprises a plastic package connection portion packaged in the plastic package housing and an installation portion protruding out of the plastic package housing. The installation support and the stator assembly are directly connected into the integrated body in the injection molding manner through the plastic package housing, thereby saving the follow-up installation process of the installation support, saving the arrangement of connecting components between the installation support and the stator assembly or the plastic package housing, reducing the number of the components of the plastic package coil motor, simplifying the structure of the plastic package coil motor and reducing material cost of the plastic package coil motor, meanwhile, simplifying production process of the plastic package coil motor, reducing labor cost of the production of the plastic package coil motor, and improving production efficiency of the plastic package coil motor.

Description

technical field [0001] The invention belongs to the field of motors, in particular to a plastic coil motor. Background technique [0002] In the prior art, the connection mode between the mounting bracket of the coil motor and the motor body is as follows: two anti-vibration rubber rings are respectively arranged at both ends of the motor body in the axial direction, and two semicircular hollow holes are respectively arranged at both ends of the mounting bracket Support two anti-vibration rubber rings respectively, and then buckle two metal arc-shaped bending pieces on each anti-vibration rubber ring, and make the bottom end of each metal arc-shaped bending piece snap connected with the mounting bracket, Finally, through the combination of screws and nuts, the opposite top ends of the two metal arc-shaped bending pieces buckled on the same anti-vibration rubber ring are fastened together, thereby realizing the fast connection between the mounting bracket and the motor body. ...
