(1) Ratings and Specifications
* 1. These items and torque-motor speed characteristics quoted in combination with an SGDM SERVO-
PACK are at an armature winding temperature of 20°C.
* 2. The values in the parentheses are those for motors with holding brakes.
Note: These characteristics are values with the following iron plate (heat sinks) attached for cooling.
SGMGH-03, 06, and 09: 400 × 400 × 20 (mm)
SGMGH-12, 20, 30, 40 and 55: 550 × 550 × 30 (mm)
(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)
