These items and torque-motor speed characteristics quoted in combination with an SGDM/SGDHSERVOPACK are at an armature winding temperature of 20°C (68°F).* 2. The values in the parentheses are those for motors with holding brakes.* 3. These values are reference values.Note: These characteristics are values with the following aluminum plates (heat sinks) attached for cooling.SGMSH-10, 15, and 20: 300 × 300 × 12 (mm) [11.81 × 11.81 × 0.47 (in)]SGMSH-30, 40, and 50: 400 × 400 × 20 (mm) [15.75 × 15.75 × 0.79 (in)](2) Holding Brake Moment of InertiaThe moment of inertia of the servomotor with holding brake is expressed using the followtin equation.(The moment of inertia of the servomotor with holding brake) = (rotor moment of inertia) + (brake moment of inertia)Brake Moment ofInertiaServomotorSGMSH-10AA10DA15AA15DA20AA20DA30AA30DA40AA40DAkg·m 2 ×10 -4 0.325 2.10lb·in·s 2 x10 -3 ∗ 0.288 1.8650AA50DA* These values are reference values.3-34
