Abstract: PROBLEM TO BE SOLVED: To provide a dynamic unbalance measurement device capable of finding an unbalance amount of a workpiece 2 such as a rotor of a rotary electric machine at low cost and with high precision. SOLUTION: A workpiece 2 is vibrated in synchronism with a rotation cycle at an amplitude corresponding to an unbalance amount by a rotary power transmitter 5 which rotates the workpiece 2 in a floating state.

Next, a first average of the unbalance amount in the first phase section and a second average of the unbalance amount in the second phase section are found. The unbalance amount of the workpiece 2 is obtained from the first average and the second average.  Thereby, a measuring period of time becomes 3/4 cycle and it is possible to realize a high speed of measuring of the unbalance amount.
