平衡計器。[Claims for Utility Model Registration] 1. In an automatic balancing instrument that compares an input signal and a feedback signal with a deviation amplifier and automatically balances the DC motor by driving a DC motor according to the deviation, a hysteresis output is generated based on the deviation output of the deviation amplifier. An automatic balancing instrument characterized by comprising a hysteresis circuit that generates hysteresis, and a drive circuit that drives a DC motor in forward and reverse rotation according to the positive and negative outputs of the hysteresis circuit. 2. The automatic balance meter according to claim 1, further comprising a zero detection circuit that detects zero output of the hysteresis circuit and locks the DC motor.
