Abstract
The utility model provides a three-freedom-degree motor which comprises a shaft body, an inner sphere for horizontal rotation and an outer sphere for horizontal and vertical rotation. The shaft body comprises a cylindrical cylinder, a first sphere is arranged at one end of the cylindrical cylinder, a first stator winding is positioned in the first sphere, a first rotor winding and a second stator winding are arranged in the inner sphere, four protrusions are arranged on the outer portion of the inner sphere, and a second rotor winding and four guide grooves are arranged in the outer sphere. The three-freedom-degree motor is reliable in structure, multi-freedom-degree motion in space can be achieved, and design of a mechanical system can be greatly simplified by applying the three-freedom-degree motor to the fields of robots and precise instruments and the like. Compared with an ordinary multi-freedom-degree motor, the special three-freedom-degree motor saves materials, and a control system is simplified.
Description
Technical field
The utility model relates to a kind of freedom motor, especially a kind of Three Degree Of Freedom motor.
Background technology
Along with the progress of science and technology, the range of application of movement mechanism with multiple degrees of freedom is more and more wider.Traditional movement mechanism with multiple degrees of freedom is united realization by many single-degree-of-freedom motors, inevitably brings the problems such as mechanism is huge, transmission accuracy is low, control is difficult.Therefore, the research of multi-freedom electric motor and control system is more and more paid attention to, and wherein, can realize the globular motor that level, vertical and horizontal three degree of freedom rotate, and has application prospect widely.
The utility model content
The utility model proposes a kind of Three Degree Of Freedom motor, but the multifreedom motion on the implementation space has been simplified the design of mechanical system greatly.
A kind of Three Degree Of Freedom motor, comprise axis body, be used for the interior spheroid that horizontally rotates and the outer sphere that is used for horizontal and vertical rotation, described axis body comprises cylinder, one end of cylinder is provided with the first spheroid, there is the first stator winding the first spheroid inside, described interior spheroid inside is provided with the first rotor winding and the second stator winding, and its outside is provided with four projections; Described outer sphere inside is provided with the second rotor winding and guide groove.
The quantity of described guide groove is four.
Described cylinder is cylindrical column.
The Three Degree Of Freedom motor that the utility model proposes, this electric machine structure is reliable, but the multifreedom motion on the implementation space, be applied to the fields such as robot, precision instrument, can greatly simplify the design of mechanical system, compare with common multi-freedom electric motor, the Three Degree Of Freedom specific type of electric machine has been saved material, has simplified control system.
Description of drawings
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is vertical view of the present utility model.
Embodiment
As shown in Figure 1, a kind of Three Degree Of Freedom motor, comprise axis body 1, be used for the interior spheroid 2 that horizontally rotates and the outer sphere 3 that is used for horizontal and vertical rotation, axis body comprises cylindrical column, and an end of cylindrical column is provided with the first spheroid 4, the first spheroid 4 inside the first stator winding, interior spheroid 2 inside are provided with the first rotor winding and the second stator winding, its outside is provided with four projections 5, and during this motor operation, interior spheroid 2 horizontally rotates under the effect of electromagnetic force; Outer sphere 3 inside are provided with the second rotor winding and guide groove, and the quantity of guide groove is 4, and during this motor operation, outer sphere is horizontal and vertical rotation under the effect of electromagnetic force, and motor has just been realized the Three Degree Of Freedom rotation like this.This electric machine structure is reliable, but the multifreedom motion on the implementation space is applied to the fields such as robot, precision instrument, can greatly simplify the design of mechanical system, compare with common multi-freedom electric motor, the Three Degree Of Freedom specific type of electric machine has been saved material, has simplified control system.
Also need to prove, under the instruction of this specification, any equivalents or obvious variant that those skilled in the art make the utility model all should be in protection ranges of the present utility model.
