Hydromechanical rotational positioners

The index motor is a hydromechanical rotational positioner. Because the positioning is performed after speed-down by a built-in mechanical valve, smooth indexing without abruptness is ensured. Furthermore, the positioning is possible with a single index motor with an accuracy of ±0.1° on the output shaft. Indexing of an even higher accuracy is possible by combining with a speed reducer.
There two series: the compact HMI series and the standard EIS series. In addition, there is also DE series that integrates the EIS series with speed reducer. Only the hydraulic system make high-torque, high-speed indexing and space saving possible.
