Detailed Description

In the description of the present invention, it is to be understood that the terms "left", "right", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated. The terms "first", "second", etc. are used merely to distinguish different elements and should not be construed as limiting the utility model.

In the description of the present invention, unless otherwise specified, "a plurality" means two or more unless explicitly defined otherwise.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally connected; unless the movable connection is explicitly defined as a detachable connection. These connections are conventional in the art and those skilled in the art will understand the specific meaning of the above terms in the present invention according to the specific situation.

The direct current servo motor comprises a direct current motor body 1, wherein a mounting flange 3 suitable for mounting a motor on a modern electric spark machine or medical equipment is fixedly connected to an end cover of the direct current motor body 1 close to one end of an output shaft 2, a speed measuring generator 4 is fixedly connected to the end cover of the direct current motor body 1 far away from one end of the output shaft 2, and the speed measuring generator 4 is coaxially connected with the direct current motor body 1.

The mounting flange 3 is square with round corners, mounting holes 32 are formed at the four corners, and the periphery of the mounting holes 32 extends inwards to form a reinforcing plate 31. The power input line 12 of the dc motor body 1 and the potential output line 42 of the tachogenerator 4 are arranged alternately. 2 motor brush holders 11 of the direct current motor body 1 are horizontally and linearly arranged and are respectively arranged on two sides of the direct current motor body 1; the 2 generator brush holders 41 of the tachogenerator 4 are orthogonally arranged at 90 degrees and are all positioned at the upper side of the tachogenerator 4. The motor brush holder 11 and the generator brush holder 41 include a brush box, a spiral spring, and a pressure finger, which keep the carbon brush in contact with the sliding surface under pressure.

The brush holder is a mechanical guide groove which is used for containing and maintaining the position of the carbon brush in the brush motor. It is composed of brush box, spiral spring and pressing finger. And a member for mounting the carbon brush and keeping it in contact with the sliding surface under pressure. The tachogenerator is a miniature special motor with output electromotive force proportional to rotating speed. The winding and magnetic circuit of the tachogenerator are precisely designed, and the output electromotive force E and the rotating speed n are in a linear relationship, namely E is Kn, and K is a constant. The polarity of the output electromotive force changes accordingly when the rotation direction is changed. When the mechanism to be measured is coaxially connected with the tachogenerator, the rotating speed of the mechanism to be measured can be obtained only by detecting the output electromotive force, so the mechanism to be measured is also called as a speed sensor.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
