Abstract
The utility model provides an injection -molded rotor, including rotor core, rotor core's outer circumference interval is equipped with a plurality of sand grips, install the magnetic shoe between the sand grip, rotor core's outer wall is equipped with slot -Filler, the one end opening is sealed to the slot -Filler three -terminal, the inner wall of magnetic shoe is closed with slot -Filler's opening, the outer circumference coat of magnetic shoe covers and has the plastics package to mould the layer. Compared with the prior art, the beneficial effects of the utility model are that: 1 )The setting up of sand grip makes before moulding plastics the magnetic shoe to fix in the tram, 2 )Rubber circle set up the vibration that can reduce the rotor and produce in the course of the work, play the cushioning effect, increase of service life.
Description
Technical field
This utility model is related to technical field of motor manufacture, specifically a kind of injection rotor.
Background technology
In order to realize the high efficiency of motor, magnetic flux must be as high as possible.Its precondition is that magnet is accurately pre- at its
Be arranged at first defined location on rotor with as far as possible optimally with motor stator synergism.Magnet passes through in its position
Plastic overmold portion is fixed.To carry out coating and injection moulding, stacked armature core is inserted in injection mold together with axle and magnet.
That is, carry out just magnet must being placed at correct final position before coating and injection moulding in injection mold.Conventional method is
Magnet is fixed on rotor with binding agent, the defect of this fixing meanss is：Binding agent can melt under the high temperature conditions failure,
So as to cause magnet to come off, and then cause magnetic flux to reduce, affect motor working efficiency.
Utility model content
The purpose of this utility model is to solve defect present in prior art, there is provided one kind is molded rotor to solve
The problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows：
One kind injection rotor, including rotor core, it is characterised in that：The excircle of the rotor core is interval with some
Raised line, is provided with magnetic shoe between the raised line, the outer wall of the rotor core is provided with filling slot, and the end seal of the filling slot three closes one
The closure of openings of filling slot is coated with plastics covered plastics layer by end opening, the inwall of the magnetic shoe on the excircle of the magnetic shoe.
Preferably, each magnetic shoe at least one filling slot of correspondence.
Preferably, the axial direction of the rotor core is equipped with rubber ring, the central axis and rotor core of the rubber ring
Central axes.
Beneficial effect
Compared with prior art, the beneficial effects of the utility model are：1）The setting of raised line causes the magnetic shoe before injection can
To be fixed on tram；2）The setting of rubber ring can reduce the vibration that rotor is produced in the course of the work, play buffering and make
With increasing the service life.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1, rotor core；2nd, magnetic shoe；3rd, plastics covered plastics layer；4th, filling slot；5th, raised line；6th, rubber ring.
Specific embodiment
To make to have a better understanding and awareness architectural feature of the present utility model and the effect reached, to compared with
Good embodiment and accompanying drawing coordinates detailed description, is described as follows：
One kind injection rotor, including rotor core 1, the excircle of the rotor core 1 is interval with some raised lines 5, institute
State and magnetic shoe 2 is installed between raised line 5, the outer wall of the rotor core 1 is provided with filling slot 4, and the end seal of the filling slot 4 three closes one end
The closure of openings of filling slot 4 is coated with plastics covered plastics layer 3 by opening, the inwall of the magnetic shoe 2 on the excircle of the magnetic shoe 4.
Each at least one filling slot 4 of correspondence of magnetic shoe 2, the axial direction of the rotor core 1 is equipped with rubber ring 6, in the rubber ring 6
The central axes of heart axis and rotor core 1.
Before injection, magnetic shoe 2 is pasted between raised line 5, using plastics by between magnetic shoe 2 produce space and filling slot
4 injections, in the excircle coating plastic covered plastics layer 3 of magnetic shoe 2 after the completion of injection.Injection rotor will not be due to height in work process
Temperature causes magnetic shoe 2 to come off and causes the reduction of working rotor efficiency, while the setting of rubber ring 6 can be reduced effectively in the course of work
Vibration, play cushioning effect, the service life of Extending Rotor.
Ultimate principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Simply principle of the present utility model, this utility model also has respectively on the premise of without departing from this utility model spirit and scope
Changes and improvements are planted, these changes and improvements are both fallen within the range of claimed this utility model.This utility model is required
Protection domain defined by appending claims and its equivalent.
