3 Specifications and Dimensional Drawings
3.5.1 SGMSH Servomotors (3000min
-1
) Without Gears
3-34
(b) 400-V Class
* 1. These items and torque-motor speed characteristics quoted in combination with an SGDM/SGDH
SERVOPACK 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 cool-
ing.
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 Inertia
The moment of inertia of the servomotor with holding brake is expressed using the following equation.
(The moment of inertia of the servomotor with holding brake) = (rotor moment of inertia) + (brake moment of inertia)
* These values are reference values.
