PURPOSE:To enable continuous measurement of nonsteady dynamic load torque characteristic from the static condition to the steady operation by introducing detection output to a dynamic load torque computation circuit detecting a vibrating acceleration and a rotary phase in an unbalanced surface. CONSTITUTION:The sine value and the cosine value of a rotary phase detected with a rotary phase detector 6 are computed 9 and 10 separately. The sine value is multiplied 11 by a vibrating acceleration detected with a vibrating acceleration detector 7 while the cosine value is multiplied 12 by an vibrating acceleration detected with a vibrating acceleration detector 8. Then the output of the multiplication 12 is inverted 13 and added 14 to the other multiplication output. The addition output is applied to an arithmetic circuit 15 to multiply the unbalanced quantity me times and a dynamic load torque TDL is measured. |
