Abstract
The invention relates to a motor rotor with dislocated magnet adhering, comprising a rotating shaft, a slip ring, a rotor core and a magnet. The slip ring sleeves the rotating shaft and drives the rotor to rotate. The rotor core is provided with an open slot used for mounting the magnet. The magnet includes a left section and a right section, and the left section and the right section are arranged in a dislocated magnet adhering mode. Therefore, interaction between the permanent magnet and the rotor core is reduced, the cogging torque is reduced, and the two bottlenecks, namely, magnet adhering and magnetizing, are overcome due to dislocated magnet adhering.
Description
Technical field
The present invention relates to motor device field, be specifically related to a kind of rotor of the glutinous magnetic that misplaces.
Background technology
At present, along with the development of electric machines control technology, the application of permanent magnet synchronous motor in high-performance AC servo control is more and more extensive, but, the same with the magneto of other types, due to permanent magnet and grooved armature interaction unshakable in one's determination, permanent magnet synchronous motor inevitably produces cogging torque, cause torque ripple, and produce vibration and noise, affect control accuracy and the setting accuracy of system.
Therefore, be necessary to provide the rotor of the glutinous magnetic of a kind of dislocation solving the problems of the technologies described above.
Summary of the invention
Technical problem solved by the invention is: the rotor that a kind of glutinous magnetic of dislocation that improves system control accuracy and setting accuracy is provided.
For achieving the above object, the technical solution used in the present invention is: a kind of rotor of the glutinous magnetic that misplaces, comprise: rotating shaft, slip ring, rotor core and magnetite, described slip ring sleeve is located in rotating shaft, described slip ring rotor driven rotates, described iron core is provided with the fluting for magnetite is installed, and described magnetite divides left and right two sections of settings, described left section of magnetite and the right section of glutinous magnetic setting of magnetite mutual dislocation.
Beneficial effect of the present invention is: the present invention is by sticking magnetic setting by left section of magnetite and right section of magnetite mutual dislocation, thereby having reduced permanent magnet and rotor core interacts, reduce cogging torque, and due to the glutinous magnetic of dislocation, thereby overcome glutinous magnetic and the difficulty two large bottlenecks that magnetize.
Brief description of the drawings
Fig. 1 is the structural representation of rotor in the present invention.
In Fig. 1: 1, rotating shaft, 2, slip ring, 3, magnetite, 30, left section of magnetite, 31, right section of magnetite.
Embodiment
In order further to understand the present invention, below in conjunction with embodiment, the preferred embodiment of the invention is described, but should be appreciated that these are described is for further illustrating the features and advantages of the present invention, instead of limiting to the claimed invention.
As shown in Figure 1, a kind of rotor of the glutinous magnetic that misplaces, comprise: rotating shaft 1, slip ring 2, rotor core and magnetite 3, described slip ring 2 is sheathed in rotating shaft 1, described slip ring 2 rotor drivens rotate, described iron core is provided with the fluting for magnetite 3 is installed, 3 points of left and right two sections of settings of described magnetite, described left section of magnetite 30 and the glutinous magnetic setting of right section of magnetite 31 mutual dislocation.
The present invention passes through glutinous to left section of magnetite 30 and right section of magnetite 31 mutual dislocation magnetic setting, thereby has reduced permanent magnet and rotor core interaction, has reduced cogging torque, and because dislocation sticks magnetic, thereby overcome glutinous magnetic and the difficulty two large bottlenecks that magnetize.
