Abstract
The utility model provides a permanent magnetic rotor for electric motors, comprising an inner rotor iron core (1), a rotor shaft (2), an outer rotor iron core (4), and one or one more magnet ring or magnetic shoe (5). The rotor shaft is passed through the shaft hole of the inner rotor iron core (1) and is tightly fixed with the inner rotor iron core (1). The one or one more magnet ring or magnetic shoe (5) is arranged on the outer side of the outer rotor iron core (4), and the characteristic is that the inner rotor iron core (1) is connected with the outer rotor iron core (4) through an elastic sheet (3). The utility model adopts the structure of the connection of inner rotor iron core and the outer rotor iron core through the elastic sheet, which not only effectively eliminates the vibration and the noise of the electric motor, but also easily controls the elasticity, and supports large torque, and is applicable to large power permanent magnetic electric motors.
Description
Technical field
The utility model is a kind of p-m rotor of motor, and particularly a kind of p-m rotor by electronically controlled permanent magnetic Ac servo motor and DC Brushless Motor belongs to the improvement technology of the p-m rotor of motor.
Background technology
Traditional p-m rotor by electronically controlled permanent magnetic Ac servo motor and DC Brushless Motor generally has two kinds of structures, a kind of is the rigid structure rotor, another kind is the rubber structure rotor, the rigid structure rotor can't be eliminated the vibration and the noise of motor, more obvious in high-power permanent magnet motor especially, the rubber structure rotor is semi-rigid rotor, certain elastic buffer effect is arranged, but the consistency and elasticity of rubber is restive, and is not suitable for high-power permanent magnet motor owing to not bearing big moment.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of and not only is fit to high power motor, and can reduce the p-m rotor of the motor of vibration and noise.The utility model design is ingenious, simple in structure, function admirable.
Press the p-m rotor of a kind of motor of this purpose design, include internal rotor iron core, armature spindle, outer rotor iron core and one or more magnet rings or magnetic shoe, armature spindle passes the axis hole of internal rotor iron core, and tighten together with the internal rotor iron core, the outer rotor iron core outside is equiped with one or more magnet rings or magnetic shoe, and its architectural feature is that above-mentioned internal rotor iron core is connected by flexure strip with outer rotor iron core.
The utility model is because the structure that adopts internal rotor iron core and outer rotor iron core to be connected by flexure strip, and therefore, it not only can effectively eliminate the vibration and the noise of motor, and elastic force controls easily, can bear big moment, suitable high-power permanent magnet motor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1, the p-m rotor of this motor, include internal rotor iron core 1, armature spindle 2, outer rotor iron core 4 and one or more magnet rings or magnetic shoe 5, armature spindle 2 passes the axis hole of internal rotor iron core 1, and tighten together with internal rotor iron core 1, outer rotor iron core 4 outsides are equiped with one or more magnet rings or magnetic shoe 5, and internal rotor iron core 1 is connected by flexure strip 3 with outer rotor iron core 4.
Claims (1)
