PROBLEM TO BE SOLVED: To provide a dynamometer system capable of performing evaluation equivalent in a system provided with a load cell in a dynamometer system provided with an axial torque meter.SOLUTION: The dynamometer system includes an encoder for detecting a dynamometer angular velocity, an axial torque meter for detecting axial torque between load equipment and the dynamometer, and a control device 6A for controlling the dynamometer on the basis of the dynamometer angular velocity ωM and an axial torque meter detection value Tsh. The torque control device 6A includes an arithmetic torque calculation part 61A for calculating an arithmetic torque value Tcal by adding a value obtained by multiplying a dynamometer angular velocity ωM×s by moment of inertia JM and the axial torque meter detection value Tsh, and an arithmetic torque controller 62A for calculating a torque current command value Tdyref to be an input to an inverter on the basis of a command value Tref inputted from the outside and the arithmetic torque value Tcal. |
