ABSTRACT:
A device for correcting the torque detected by an electric dynamometer, which is capable of very accurately correcting loss torques of the operation-type dynamometer based upon a simply constructed mechanism. Among many loss torques involved in the operation-type electric dynamometer, the windage-loss torque which plays a major role is accurately corrected as a function of the atmospheric pressure, atmospheric temperature and rotation speed, thereby to very accurately correct the torque.
