    The swing plug (45h) of reciprocally swinging acts on bar shaped slide opening (42d) and causes flexible flat board (42b), carbon brush body (42c) Reciprocal telescopic movement, the carbon brush body (42c) radical length of itself and winding (3) contact position in rotation process constantly become Change, avoid showing for long term wear winding (3) a certain fixed Circular test caused by being fixed due to carbon brush body (42c) radical length As considerably increasing effective wear area, reducing rate of depreciation；
    Step 3, the regulation of the flexible damping of carbon brush body (42c)：
    Step 3.1, elastic force action type adjusting method：
    Rotate to put bolt (44b) on described and make it rotate stepping and then adjust and stage clip (44d) decrement is put on described, and then adjust Pressure of the regulation briquetting (44a) to the flat board (42b) that stretches is saved, and then adjusts the flexible flat board (42b), carbon brush body Frictional damping when (42c) is flexible；
    Step 3.2, contact adjusting method is crimped：
    Bolt (44b) is put on described to be stepped down by until the regulation inserted link (44c) is crimped on the regulation briquetting (44a) When, continue to screw and bolt (44b) is put on described the regulation inserted link (44c) is persistently compressed regulation briquetting (44a), and then make institute Pressure jump of the regulation briquetting (44a) to the flat board (42b) that stretches is stated, adjusts the flexible flat board (42b), carbon brush body (42c) Frictional damping when flexible is uprushed.
  3. 3. a kind of adjusting method of the flexible adjustable auto-transformer of damping of carbon brush body according to claim 2, its It is characterised by：The connecting lead wire (43c) is made up of metal material.
  4. 4. a kind of adjusting method of the flexible adjustable auto-transformer of damping of carbon brush body according to claim 3, its It is characterised by：The connecting lead wire (43c) is made up of copper or aluminum material.
