Abstract
The utility model provides a DC (direct current) micro-motor rotor which comprises a rotation shaft, a rotor iron core, core sheets, an inner hole and rotor windings. The rotor windings are wound on the assembled core sheets of the rotor iron core. The outside of each core sheet is formed into a U shape. The height of each rotor winding is consistent with the height of the rotor iron core, and thus the height of the rotor is reduced. At the same time, coils of each group of windings are correspondingly reduced, and thus the internal space of the motor is saved and the cost of raw materials is reduced, and also the moment of a force is increased. The rotation shaft penetrates through the inner hole in the center of the rotor iron core. The DC micro-motor rotor saves the internal space of the DC micro-motor, helps to reduce the size of the DC micro-motor and at the same time increase the moment of a force, and thus the DC micro-motor rotor is convenient for carrying and achieves good effects in use.
Description
Technical field
The utility model relates to technical field of motors, will relate to particularly a kind of direct-flow micromachine rotor.
Background technology
The rotor core of existing micromachine is all that the punching by plane is formed by stacking, after being wound around upper rotor part winding, rotor winding will be projected into rotor core outside, the height of whole rotor will surpass the height of original rotor core, some is large to cause rotor integral body to become, and micromachine requires motor smaller, in assembling process, fraction defective is higher and the stability of motor characteristic is difficult to guarantee, so also seem extremely important in the inner space of saving motor.
Summary of the invention
In order to save the space of direct-flow micromachine inside, increase moment simultaneously, the utility model provides a kind of direct-flow micromachine rotor.
The purpose of this utility model is achieved through the following technical solutions: a kind of direct-flow micromachine rotor, comprise rotating shaft, rotor core, chip, endoporus, rotor winding, its rotor winding is wrapped on the chip of the rotor core having assembled, the chip exterior of rotor core becomes U-shaped, the height of rotor winding is just in time consistent with the height of rotor core, reduced the height of rotor, raw-material cost has been saved again in the space of simultaneously having saved motor internal at the coil of every group of winding also corresponding minimizing, also increased moment simultaneously, rotating shaft is through the endoporus of rotor core center.
The beneficial effects of the utility model are: saved the space of direct-flow micromachine inside, can make the volume of DC micromotor less, carried more conveniently, also increased moment simultaneously, result of use can be better.
Accompanying drawing explanation
Fig. 1 is structural scheme of mechanism of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
The technical solution of the utility model is: a kind of direct-flow micromachine rotor, comprise rotor core 1, rotating shaft 2, rotor winding 3, endoporus 4, chip 5, its rotor winding 3 is wrapped on the chip 5 of the rotor core 1 having assembled, the outside one-tenth U-shaped of chip 5 of rotor core 1, the height of rotor winding 3 is just in time consistent with the height of rotor core 1, has reduced the height of rotor, the space of having saved motor internal, also increased moment, rotating shaft 2 is through the endoporus 4 of rotor core 1 center simultaneously.
