Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention is described in detail below with reference to the attached drawings.
As shown in fig. 1, the rotor structure capable of increasing the effective working magnetic flux of the motor provided by the present invention includes an iron core 1 and two magnets 2 both disposed at the periphery of the iron core 1, the two magnets 2 are disposed at intervals, the magnets 2 are arc-shaped, and the central angle corresponding to the arc-shaped edge of the magnet 2 is 139 ° and 149 °.
In practical use, the utility model is of a five-groove structure, namely: the iron core 1 comprises a body 5 and five winding pieces 6 arranged on the periphery of the body 5, the iron core 1 is provided with a through hole 7 for assembling a rotating shaft, and the winding pieces 6 are used for winding wires.
For the five-slot mechanism, because the wire is wound across the two arms, the higher the magnetic flux passing through the two arms, the higher the performance of the motor; based on the principle, the magnetic permeability of iron is far greater than that of air, so that the length of the magnet 2 is increased, the magnetic field of the magnet 2 can be better collected on the winding piece 6 made of iron, and the performance of the motor is improved in a magnetic beam lifting mode.
Compared with the angle range of the utility model, if the angle is larger than the range, the performance is improved a little, the waste of the magnet 2 material is caused, and even the magnetic short circuit is caused by serious conditions; if the angle is smaller than the above angle, the performance of the motor cannot be ensured.
In this embodiment, the central angle of the arc-shaped side of the magnet 2 is 144 °. The angle is an optimal scheme in the range, and the phenomenon of magnetic short circuit is avoided to the maximum extent on the premise of ensuring that the performance of the motor is improved.
In this embodiment, the present invention further includes a sleeve 3, two magnets 2 are mounted on the inner side wall of the sleeve 3 in a manner of facing each other, and the iron core 1 is abutted against the two magnets 2 respectively. The sleeve 3 shields the magnet 2, so that the magnetic field generated by the magnet 2 does not interfere with other surrounding components.
Specifically, the two ends of the magnet 2 are respectively provided with an inclined plane 4, and the inclined planes 4 are positioned between the magnet 2 and the sleeve body 3. This inclined plane 4 is used for compensating, when the magnetite 2 leads to warping because of generating heat or receiving other external forces promptly, and the clearance between this inclined plane 4 of accessible and the cover body 3 compensates, guarantees that magnetite 2 can not split because of the atress is big.
Specifically, winding member 6 includes connecting portion 8 and spacing portion 9, connecting portion 8 connect in body 5, spacing portion 9 sets up in connecting portion 8, and spacing portion 9 is used for carrying on spacingly to connect in connecting portion 8 around, and spacing portion 9 is located between connecting portion 8 and magnetite 2. That is, the connecting portion 8 and the limiting portion 9 form a T-shaped structure, so that the conducting wire can be positioned around the connecting portion 8 and then limited by the limiting portion 9, and the conducting wire cannot be scattered during rotation.
Specifically, the iron core 1 and the five wire winding members 6 are integrally formed, specifically, integrally formed by punching.
