Abstract
PURPOSE:To achieven an accurate measurement of torques by correcting the transmission torque value detected of a rotor according to the rotation speed thereof. CONSTITUTION:As a load torque grows large, a detection plate 12 on the load side delayed in the rotation phase from a detection plate 11 on the driving side. On the contrary, the rotation phase of the detection plate 12 advances due to an inertia moment on the load sise at the deceleration and a signal according to a time lag in the phase is outputted by a detection circuit 33 with an advance/lag sign thereof and a torque outputted before the correction is obtained by selecting a required value for the amplification value of the output. Here, a square wave of the frequency proportional to the rotational frequency obtained from a detection element 15 and a waveform shaping circuit 32 is made a D.C. voltage by way of a monostablemultivibrator 35 and a smoothing circuit 36 and provided to a correction value setting circuit 37 to obtain a correction value. The correction value is provided to a substraction circuit 38 with the output of an amplifier 34 to obtain a true value of the torque.
