[description of drawings]

Fig. 1 is the schematic perspective view of the utility model one preferred embodiment.

Fig. 2 is another schematic perspective view embodiment illustrated in fig. 1.

Fig. 3 is a perspective exploded view embodiment illustrated in fig. 1.

[embodiment]

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Seeing also Fig. 1 to Fig. 3, is a preferred embodiment of the utility model gear motor, and it comprises stator 1, rotor 2, shell 3 and output shaft 4.

Described stator 1 comprises silicon steel laminations 10 and a plurality of enamelled wire 12.Described silicon steel laminations 10 is body in the form of a ring, which is provided with a cannelure (not indicating among the figure), and described enamelled wire 12 rings are located in the cannelure.The center of described silicon steel laminations 10 is provided with manhole 14, inserts for rotor 2.Described silicon steel laminations 10 is a magnet, and it is connected with the power supply (not shown), and produces magnetic field, rotates to promote rotor 2.

Described rotor 2 comprises iron core 20, magnet steel 22, bearing 24 and driver pinion 26, and described magnet steel 22 is a polylith, and ring is located at the periphery of iron core 20.Described bearing 24 is embedded in the center of iron core 20, and described bearing 24 is provided with through hole (among the figure indicate), and described driver pinion 26 is located in the through hole.The external diameter of the magnet steel 22 of described rotor 2 is identical with the internal diameter of silicon steel laminations 10 manholes 14, and magnet steel 22 embeds in the manhole 14.

Described shell 3 comprises first accepting groove 30 and second accepting groove 32, and the notch of described first accepting groove 30 and second accepting groove 32 is towards on the contrary, and the two overlaps, and described second accepting groove 32 is partially submerged in first accepting groove 30.Described output shaft 4 is located in first accepting groove 30, and is with driven gear wheel 40 by bearing 41 on the output shaft 4.Described second accepting groove, 32 housing stator 1 and rotor 2, and second accepting groove 32 is provided with a through hole 320, and the driver pinion 26 of described rotor 2 passes through hole 320, is meshed with driven gear wheel 40.

The rotor 2 of said gear motor rotates under the action of a magnetic field of stator 1, and the driver pinion 26 of described rotor 2 is meshed with driven gear wheel 40, reduces the rotating speed of driver pinion 26 by driven gear wheel 40, thereby makes the suitable rotating speed of output shaft 4 outputs.

Described gear motor is by establishing driver pinion 26 and the driven gear wheel 40 that is meshed on rotor 2 and output shaft 4, the gear number is few, thereby makes gear motor internal structure compactness, and power consumption is few, and efficient improves.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
