CHART ILLUSTRATING EFFECT OF INERTIA INDEX E<br />

ON SERVOMOTOR SIZE<br />

FIGURE 10<br />

CONCLUDING l3mARKs<br />

The discussion has shown that <strong>the</strong> response characteristics <strong>of</strong><br />

hydraulic servomotors with mechanical feedback may be represented by linear<br />

equations. These equations are defined in terms <strong>of</strong> <strong>the</strong> size <strong>of</strong> <strong>the</strong><br />

servomotor and <strong>the</strong> load conditions. From <strong>the</strong>se relations, equations which<br />

define <strong>the</strong> dimensions <strong>of</strong> <strong>the</strong> servomotor i n terms <strong>of</strong> <strong>the</strong> known load, and<br />

desired response characteristics can be obtained. BY means <strong>of</strong> <strong>the</strong>se relations<br />

<strong>the</strong> rational design <strong>of</strong> <strong>the</strong> servomotor to meet specifications on<br />

ei<strong>the</strong>r <strong>the</strong> transient or frequency response characteristics is made<br />

possible.<br />
