Abstract

The invention discloses a combined type two-degree-freedom mixed type stepping motor with an orthogonal cylindrical structure for a robot and an application thereof. The combined type two-degree-freedom mixed type stepping motor comprises a first-degree-freedom motor, a second-degree-freedom motor and an output shaft, wherein the first-degree-freedom motor is of a cylindrical structure, the first-degree-freedom motor rotates about a rotating axis which is the diameter direction of the bottom of the cylindrical structure, the second-degree-freedom motor is of a cylindrical structure and is arranged on the outer edge of the first-degree-freedom motor, the axis center of the second-degree-freedom motor is vertically orthogonal to the axis center of the first-degree-freedom motor, the second-degree-freedom motor rotates about a rotating axis which is the shaft center of the first-degree-freedom motor, and the second-degree-freedom motor retains independent movement relative to the first-degree-freedom motor during the rotating process of the first-degree-freedom motor, so that the output shaft arranged on the outer side of the second-degree-freedom motor realizes two-degree-freedom movement. The research and development period of a product is shortened, and the performance of the product is improved. Practical utilization, industrialization and commercialization of multi (two)-degree-freedom motors are further facilitated.

Description

technical field

[0001] The invention relates to a combined type orthogonal cylindrical structure two-degree-of-freedom hybrid stepping motor and its application. Background technique

[0002] Traditional asynchronous motors and synchronous motors have only one degree of freedom of rotor rotation, and the rotation motion can be transformed into linear motion through the cooperation of gears or worms. In many occasions, linear or rotational motion is sufficient to meet the needs of the controlled object; but in some more complex motion occasions (such as robot arm control, radar positioning control, etc.), one degree of freedom cannot meet the needs, and must have The purpose can only be achieved by the cooperative use of multiple electric motors. However, if the control is implemented by multiple motors, many problems will arise, such as complex mechanical structure, increased volume and weight, and difficulty in ensuring accuracy and dynamic characteristics. It is precisel...
