PURPOSE:To enable an excellent measurement of dynamic unbalance correction magnitude of a rotating body, by controlling with the central control circuit by connecting such apparatuses as input of data of vibration, unbalance calculation, balance testing by signal emitting and receiving circuits. CONSTITUTION:A vibration data input apparatus is consists of A/D converter 15 converting extracted data 14 of element of number of revolutions of a driven body 10 into vibration data of digital quantity, apparatus 30 issuing an interrupting signal when the body 10 reaches the specified number of rotations and information exchanging circuit 34. Further, an unbalance calculating apparatus is provided with balancing method selecting circuit, mode resolving circuit, correction magnitude calculating circuit, etc. Further, control is made by the central control apparatus after connecting vibration data input apparatus, unbalance calculating apparatus and balance testing apparatus with the signal emitting and receiving circuits. Consequently, rapid and stabilized controls become available, without passing artificially through revolution tests of balancing of a plurality of units, simultaneously. |
