In the direct drive spool valve using torque motor, the magnetic hysteresis is relatively intense, so it is neccessary to reduce the magnetic hysteresis for operating the valve with high accuracy. Therefore a measuring system which is able to measure accurately and easily has been developed to examine detailedly the magnetic hysteresis of this valve. This measuring system of the magnetic hysteresis is consist of the direct drive spool valve using torque motor, a control amplifier of driving this valve, current probe, measuring station and personal computer. The data file can be transferred between the measuring station and personal computer each other by means of Ethernet connection. And, AD and DA convertor modules are included in the measuring station. Some magnetic hysteresis loop of the valve was measured by using developed measuring system of above mentioned construction. Consequently, it became clear that the nature of the hysteresis of this valve is relatively regular.
