Abstract
The utility model relates to a permanent magnetic rotor for a motor, comprising a rotor iron core (1) and a rotor shaft (2). The rotor shaft (2) penetrates through the shaft hole of the rotor iron core (1) to fasten with the rotor iron core (1). The utility model is characterized in that the outside of the rotor iron core (1) is provided with a plurality of bosses (11), and a plurality of magnetic shoes (3) are respectively buckled and installed between two contiguous bosses (11). Because the utility model adopts the structure that the rotor iron core is provided with a plurality of bosses and the magnetic shoes are buckled and installed on the rotor iron core by the bosses, the well bonding and positioning between the magnetic shoes and the rotor iron core can be ensured. In addition, the contact surface of the inner side of the magnetic shoes and the outer side of the rotor iron core is coated with an adhesive, which further ensures the firm and reliable assembly between the rotor iron core and the magnetic shoes. In addition, the utility model is provided with a plurality of slots on the rotor iron core for effectively preventing the magnetoconductivity and magnetic leakage of the rotor shaft, and has simple structure, easy assembly and low production cost.
Description
1, technical field:
The utility model is a kind of p-m rotor that is used for motor, especially for the p-m rotor by electronically controlled permanent magnetic Ac servo motor and DC Brushless Motor, belongs to the renovation technique of motor p-m rotor.
2, background technology:
The magnetic shoe that tradition is used for by the p-m rotor of electronically controlled permanent magnetic Ac servo motor and dc brushless motor is to be bonded at the rotor core periphery with epoxy resin plaster, use after the colligation of no latitude band then and the grinding periphery, because no latitude band has taken the air gap of motor, causes the decline of motor efficiency; In addition, for preventing armature spindle magnetic conduction leakage field, need between rotating shaft and rotor core, to install aluminium cover or copper sheathing and come to have increased the assembly difficulty of rotor like this, so that the also corresponding increase of production cost of motor every magnetic.
3, summary of the invention:
The purpose of this utility model is to overcome above-mentioned shortcoming, a kind of efficient that not only can improve motor is provided, and can simplifies assembly technology, the hydromagnetic rotor that is used for motor that reduces production costs.The utility model design is ingenious, simple in structure, function admirable.
The structural representation of the utility model p-m rotor as shown in drawings, include rotor core (1), armature spindle (2), armature spindle (2) passes the axis hole of rotor core (1), and tighten together with rotor core (1), it is characterized in that rotor core (1) outside is provided with several boss (11), several magnetic shoes (3) difference spiral-lock is between adjacent two boss (11).
Above-mentioned boss (11) is made the indent dovetail shaped of fluted (14) for both sides, and turn up at magnetic shoe (3) two ends, and the folded up portion add-drop is in the groove (14) of adjacent dovetail shaped boss (11) side.
Scribble adhesive on the contact-making surface in above-mentioned magnetic shoe (3) inboard and rotor core (1) outside.
Above-mentioned rotor core (1) is provided with several grooves (12), and the part (13) between adjacent two grooves (12) is arranged on the position corresponding with boss (11) center.
The utility model is because employing is being provided with several boss, magnetic shoe by the structure of boss spiral-lock on rotor core on the rotor core, therefore can guarantee that the applying of magnetic shoe and rotor core has good positioning, in addition, scribble adhesive on the contact-making surface in the magnetic shoe inboard and the rotor core outside, so guaranteed that further the assembling between rotor core and the magnetic shoe is solid and reliable; In addition, the utility model is provided with several grooves on rotor core, thereby has stoped the magnetic conduction and the leakage field of armature spindle effectively, and it is simple in structure, and assembling is easy, and production cost is low.The utility model is that a kind of design is ingenious, the p-m rotor that is used for motor of function admirable.

Fig. 1 is the utility model rotor core (1) structural representation;
Fig. 2 is the local enlarged diagram at A place among Fig. 1;
The front view that Fig. 3 is assembled together for the utility model rotor core (1) and armature spindle (2).
5, embodiment:
Embodiment:
Structural representation of the present utility model as shown in Figure 1, 2, 3, include rotor core (1), armature spindle (2), armature spindle (2) passes the axis hole of rotor core (1), and tighten together with rotor core (1), it is characterized in that rotor core (1) outside is provided with several boss (11), several magnetic shoes (3) difference spiral-lock is between adjacent two boss (11).In the present embodiment, above-mentioned boss (11) is made the indent dovetail shaped of fluted (14) for both sides, and turn up at magnetic shoe (3) two ends, and the folded up portion add-drop is in the groove (14) of adjacent dovetail shaped boss (11) side.
Guarantee that further the assembling between rotor core and the magnetic shoe is solid and reliable, scribble adhesive on the contact-making surface in above-mentioned magnetic shoe (3) inboard and rotor core (1) outside.In the present embodiment, adhesive can be used high-tenacity glue.
For stoping the magnetic conduction and the leakage field of armature spindle effectively, and make structure simple as far as possible, assembling is easy, and above-mentioned rotor core (1) is provided with several grooves (12), and the part (13) between adjacent two grooves (12) is arranged on the position corresponding with boss (11) center.
When the utility model uses, can become permanent magnetic Ac servo motor and DC Brushless Motor with stator and the assembling of other parts.
