PROBLEM TO BE SOLVED: To provide a power system capable of suppressing the mixing of noise into a detection signal of a power detector for detecting driving force transmitted from an electric motor to a load while the energization of the electric motor, and properly controlling the operation of the electric motor according to the detection signal of the power detector.SOLUTION: A power system 1 is a power detector 10 having a strain body 11 in a power transmission system 3 from the electric motor 2 to the load W, and controls the operation of the electric motor 2 according to a detection signal of the power detector 10 obtained by a signal processing circuit portion 31. A ground pole 31g of the signal processing circuit portion 31 is electrically connected to the strain body 11.SELECTED DRAWING: Figure 1 |
