Abstract

The utility model relates an improved motor rotor structure, which realizes the more smooth rotation of the motor and increases the motor horsepower. The utility model is characterized in that a magnet around a silicon steel sheet of the motor rotor is designed as an oblique helix sheet and a magnet gap of each magnet pole of the silicon steel sheet is designed as a corresponded oblique helix, which results in that the magnetic polarity of the rotor is irregularly complemented with the magnetic polarity of the stator. The utility model eliminates the abortive rotation problem caused by the magnetic force interruption of the magnet gap, which realizes the more smooth rotation and increases the horsepower.

Description

Improved motor rotor Motor rotor structure

Technical field

The utility model relates to a kind of improved motor rotor Motor rotor structure, its major technique means, purpose are: the magnet of rotor outer peripheral face is set as the inclined screw sheet, the magnetic gap of silicon steel sheet also is set as corresponding inclined screw wire, and make the magnetic line of force of each magnetic pole form irregular complementary effect, reach the technique effect that not pause and transition in rhythm or melody in the time of can rotating is more smooth and easy, promote horsepower.

Background technology

Existing motor rotor Motor rotor structure, as shown in Figure 1, 2, 3, a rotating shaft is provided with a plurality of magnetic links 2 for 1 group, and silicon steel sheet 2 has several magnetic gaps 3, and forms several N, S magnetic pole, sticks on each magnetic pole silicon steel sheet and is provided with magnet 4, and again, its magnetic gap 3, magnet 4 are set as straight line L shape.Above-mentioned structure 1 has following shortcoming in fact: when it is combined in stator 5, the shell 6 (Fig. 3) energising when using, stator 5 fast, the N of circulation change, S utmost point magnetic force, act on the N, the S utmost point of rotor magnet 4 and produce rotation, and, the spacing of its magnetic gap 3, to produce the problem of " magnetic line of force interruption ", and again because of magnetic gap 3, magnet 4 L sheet linearly, there is not complementation between each magnetic pole, so have the existing picture that the magnetic line of force interrupts causing the revolving force interruption, promptly can cause the rotation pause and transition in rhythm or melody, have some setbacks, and then the shortcoming of influence horsepower.

The utility model content

A purpose of the present utility model provides a kind of improved motor rotor Motor rotor structure, solve in the above-mentioned prior art and do not have complementation between each magnetic pole, and the phenomenon that can cause the magnetic line of force to interrupt and cause revolving force to interrupt, and then cause defectives such as rotation pause and transition in rhythm or melody, horsepower deficiency.

For achieving the above object, the utility model provides a kind of improved motor rotor Motor rotor structure, and a rotating shaft has the multi-disc silicon steel sheet, and silicon steel sheet has several magnetic gaps and forms magnetic pole, and silicon steel sheet is provided with magnet; Be primarily characterized in that: each magnet is set as the skewed helix sheet, and each magnetic gap also is set as corresponding inclined screw wire.

Particularly, see also Fig. 4,5, one rotating shafts 10 have a plurality of silicon steel sheets 11, silicon steel sheet 11 has several magnetic gaps 12 and forms magnetic poles, and silicon steel sheet 11 is provided with magnet 13; Be primarily characterized in that: each magnet 13 is set as skewed helix W sheet, and each magnetic gap 12 also is set as corresponding inclined screw wire.

The utlity model has following technique effect: the magnet of rotor outer peripheral face is set as the inclined screw sheet, the magnetic gap of silicon steel sheet also is set as corresponding inclined screw wire, and make the magnetic line of force of each magnetic pole form irregular complementary effect, reach the technique effect that not pause and transition in rhythm or melody in the time of can rotating is more smooth and easy, promote horsepower, greatly improved existing motor rotor Motor rotor structure.

Embodiment

As shown in Figure 5, magnet 13 of the present utility model is set as skewed helix W sheet, therefore, its polarity is the structure of " irregular complementation ", and in other words, a N utmost point magnet 13 tiltedly extends in another S utmost point magnet 13, in the stator of packing into and do the time spent (shown in Figure 3) with N, the S utmost point magnetic line of force of stator circulation, can get the effect of " the complementary linking ", and can eliminate the problem of " magnetic line of force interrupts because of magnetic gap 12 ", reach the technique effect that keeps smooth rotation, promotes horsepower.

In addition, according to above-mentioned technological means, the utility model also can implement to be Fig. 6,7 form: magnet 23 is set as skew lines H shape, and each magnetic gap 22 of silicon steel sheet 21 also is set as corresponding skew lines shape, can get the effect of the irregular complementation of the magnetic line of force of each magnet 23 equally.

In sum, structure of the present utility model has splendid practicality really, and significant technique effect, really meets novel patent main idea, earnestly asks the gift quasi patent.

The foregoing description only is illustrative principle of the present utility model and technique effect thereof, but not is used to limit the present invention.Any those skilled in the art all can make amendment to the foregoing description under spirit of the present utility model and category.So rights protection scope of the present utility model, claims are listed as the aforementioned.
