PURPOSE:To restrict noise generation by providing auxiliary electrode via insulator on either rotor electrode or fixed electrode and by this, shorten gap distance between this auxiliary electrode and opposite electrode than standard gap distance between rotor electrode and fixed electrode. CONSTITUTION:Set up auxiliary electrode 12 via insulator 11 onto rotor electrode 3 or fixed electrode 6. It is composed that the relation between standard gap distance G1 from rotor electrode 3 to fixed electrode 6 and gap distance G2 from auxiliary electrode 12 to oposite electrode should be in G1>G2. Furthermore, auxiliary electrode 12 is made from metal such as aluminium, aluminium alloy, copper, brass and etc. |
