Chapter 8: Ratings and Characteristics
8 - 16
Note:
These characteristics have been calculated with the following aluminum heat sinks attached for
cooling:
Heat sink dimensions
12 × 12 × 0.5in. (300 × 300 × 12mm): 10A A to 20A A servomotors
18 × 18 × 0.8in. (400 × 400 × 20mm): 30A A to50A A servomotors
*1
These specifications and torque-motor speed characteristics are quoted in combination with an
SGDH servo amplifier operating at an armature winding temperature of 20°C.
