Abstract

The invention relates to the field of motors or generators, in particular to a low-voltage small-sized electric motor. The electric motor comprises a shell and a rotor magnet/stator magnet in the shell, and is characterized in that a through hole is formed in a shell area which corresponds to the rotor magnet/stator magnet; magnetic fluid is injected through the through hole and is combined with a permanent magnet. By adopting the technical scheme, the magnetic fluid is injected into the motor through the through hole, so that the magnetism of the permanent magnet is effectively enhanced, the working performance of the motor is improved, and the working efficiency of the motor is increased.

Description

A kind of motor
Technical field
The present invention relates to motor or electrical generator fields, especially low-voltage miniature electro-motor.
Background technology
The motor of prior art is all to use permanent magnet; owing to adopting the difference of the difference of material and service time, environment for use, often can cause the magnetic of permanent magnet to reduce, even loss of excitation; this has affected the service behaviour of motor, has seriously reduced motor operations efficiency and useful life.Occur that this situation solution can only be the motor more renewing or re-start magnetization to the permanent magnet of loss of excitation.
Summary of the invention
The present invention has overcome the above-mentioned defect of prior art, by the improvement to motor configuration, can carry out reinforcement to the permanent magnet in motor, strengthens the magnetic of permanent magnet, effectively improves the operating efficiency of motor, increases the useful life of motor.
Technical scheme of the present invention is: a kind of motor, comprise the rotor magnet/magnets of stator in casing and casing, it is characterized in that having through hole on the region of the corresponding casing of described rotor magnet/magnets of stator, inject magnetic fluid by described through hole and be combined with permanent magnet.
Above-mentioned a kind of motor, described through hole has closing cap.
Above-mentioned a kind of motor, has shielding cover board cover described rotor magnet/magnets of stator institute corresponding region and seal described through hole on the outer wall of described casing.
Above-mentioned a kind of motor, described through hole is more than one.
Adopt technical solution of the present invention, in motor, inject magnetic fluid by through hole, effectively strengthened the magnetic of permanent magnet, improved service behaviour and the operating efficiency of motor.
Brief description of the drawings
Fig. 1 is the surface structure schematic diagram of a kind of motor of the present invention.
Fig. 2 is exploded view shown in Fig. 1.
Fig. 3 is cutaway view shown in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:
Fig. 1, Fig. 2, Figure 3 shows that one embodiment of the invention, is the structure chart of a linear vibration motor.See shown in Fig. 1, Fig. 2, Fig. 3, comprise the permanent magnet 2 in casing 1 and casing 1, also comprise shielding cover board 3, on the region of the corresponding casing 1 of described permanent magnet 2, have through hole 11, by described through hole 11 to the interior injection magnetic fluid of casing 1, because the magnetic fluid that the characteristic of magnetic fluid is injected can be combined with permanent magnet, thereby magnetic that can reinforcement permanent magnet improves the service behaviour of motor.For the each parts of motor in protection casing 1 prevent that dust, moisture etc. from entering in casing 1; can seal through hole 11 with closing cap; certainly can also adopt as shown in Figure 2 shielding cover board 3 to cover the corresponding casing of permanent magnet region; so both can capping through hole 11; the magnetic field that can shield again permanent magnet leaks outside, thereby improves motor usefulness.
The present embodiment there is shown two through holes, and through hole can be one as required, can be also two, can be also three or more.
Be more than a concrete Application Example of the present invention, protection of the present invention is not limited for this embodiment, and all those skilled in the art change and all should include the protection range that the claims in the present invention secretary is carried according to the equivalence of disclosed content.
