Embodiment
The following describes various embodiments of the present invention, among each figure,, put on prosign and describe for same or equal member, position.
Embodiment 1
Fig. 1 is the sectional view of the motor of the embodiment of the invention 1, Fig. 2 be this motor want portion's front view, Fig. 3 is the side partial cross-sectional of Fig. 2.
This electric rotating machine is a motor, comprising: the yoke 1 that the round-ended cylinder shape is arranged; Be fixed on the magnet retainer 2 on this yoke 1; 4 utmost point magnet 3 of the rectangular shape that keeps by this magnet retainer 2, the inner peripheral surface of each magnet 3 and side are coated, are used to protect the section of magnet 3 is the thin plate 4 of the stainless steel of コ word shape; Rotate the axle 7 of supporting freely by the 1st bearing 5 and the 2nd bearing 6; Be fixed on this armature 8 on 7; Be fixed in an axle end of 7, have the commutator 10 of a plurality of commutator segments 9; And the housing 11 that is fixed in the peristome of yoke 1, peristome is sealed.
This motor comprises: utilize trip bolt 12 to be fixed on the discoideus resinous pedestal 13 of hollow on the housing 11 of aluminum; With five equilibrium the 1st～the 4th brush carrier 14a, 14b, 14c, the 14d that on this pedestal 13, by metal sheet metal, constitute of riveted and fixed at interval; Remain in each brush carrier 14a, 14b, 14c, the 14d respectively, utilize spring 15 elastic force and with the brush 16 of commutator segment 9 butts; All sides butt of all sides butt of one end and the 1st brush carrier 14a and the other end and the 2nd brush carrier 14b, be fixed on resinous the 1st 19a of vibration suppression portion on the pedestal 13 by trip bolt 12; All sides butt of all sides butt of one end and the 3rd brush carrier 14c and the other end and the 4th brush carrier 14d, be fixed on resinous the 2nd 19b of vibration suppression portion on the pedestal 13 by trip bolt 12; And one the end be connected with brush 16 and lead-in wire 20 that conductor in the other end and the pedestal 13 is connected.
Armature 8 comprises: have along the iron core 17 of a plurality of groovings of axis direction extension; And to repeat winding method constitutes Wire-wound in grooving coil 18.
In the motor of said structure, by electric current being supplied with to coil 18, thereby can utilize electromagnetic action to make armature 8 with axle 7 rotations with the brush 16 of commutator segment 9 butts of commutator 10.
In the present embodiment, all sides butt of the end of the 1st 19a of vibration suppression portion and the 1st brush carrier 14a and all sides butt of the other end and the 2nd brush carrier 14b, in addition, all sides butt of the end of the 2nd 19b of vibration suppression portion and the 3rd brush carrier 14c and all sides butt of the other end and the 4th brush carrier 14d, the high-frequency intrinsic vibration value of brush carrier 14a, 14b, 14c, 14d changes to low-frequency intrinsic vibration value.
Like this, even influence at the installation accuracy of the circularity that is subjected to commutator 10, brush carrier 14, lead-in wire 20 etc., brush 16 can not be successfully in brush carrier 14 along the direction of rotation of axle 7 with radially move, it is big that sliding friction power on the contact-making surface of commutator 10 and brush 16 becomes, the high-frequency transfer of vibration of the brush 16 that causes along with this change is under the occasion of brush carrier 14, the high-frequency vibration of brush carrier 14 also can be suppressed, and can suppress the runner is sent the generation of high-frequency harshness.
In addition, trip bolt 12 is used for pedestal 13 is fixed in the fixture of housing 11 and the fixture that pedestal 13 is fixed in vibration suppression portion 19, can reduce the part number.
In addition, the 1st 19a of vibration suppression portion and the 1st brush carrier 14a and the 2nd brush carrier 14b butt, the 2nd 19b of vibration suppression portion and the 3rd brush carrier 14c and the 4th brush carrier 14d butt, by 1 19a of vibration suppression portion, 19b respectively with 2 brush carrier 14a, 14b, 14c, 14d butt, can reduce the part number of the 19a of vibration suppression portion, 19b.
Embodiment 2
Fig. 4 is the sectional view of the motor of the embodiment of the invention 2.
In this motor, the 2A of vibration suppression portion is the part of magnet retainer 2, promptly is the extension that extends towards brush carrier 14a, 14b, 14c, 14d.This end face and the 1st～the 4th brush carrier 14a, 14b, 14c, 14d butt, the high-frequency intrinsic vibration value of brush carrier 14a, 14b, 14c, 14d is changed to low-frequency intrinsic vibration value.
Like this, this motor is also the same with embodiment 1, can suppress can suppress the runner is sent the generation of high-frequency harshness because of brush 16 vibrates the high-frequency vibration of brush carrier 14a, 14b, 14c, 14d that causes.
In addition, even on brush carrier, be formed with the extension that extends towards the magnet retainer,, also can obtain same effect with this end face and magnet retainer butt.
Embodiment 3
Fig. 5 is the sectional view of the motor of the embodiment of the invention 3.
In this motor, the 4A of vibration suppression portion is the part of sealing plate 4, it promptly is the extension that extends towards brush carrier 14a, 14b, 14c, 14d, the end face and the 1st of the 4A of this vibration suppression portion～the 4th brush carrier 14a, 14b, 14c, 14d side butt separately, the high-frequency intrinsic vibration value of brush carrier 14a, 14b, 14c, 14d is changed to low-frequency intrinsic vibration value.
Like this, this motor is also the same with embodiment 1, can suppress can suppress the runner is sent the generation of high-frequency harshness because of brush 16 vibrates the high-frequency vibration of brush carrier 14a, 14b, 14c, 14d that causes.
