Ratings and Specifications for Standard Servomotors
SGMPH Standard Servomotor Ratings and Specifications
*1
These specifications and torque-motor speed characteristics are quoted in combination with an
SGDH servo amplifier operating at an armature winding temperature of 100°C. Other values are
quoted at 20°C. All values are typical.
*2
Rated torques are continuous allowable torque values at 40°C with a 10 × 10 × 0.25in (250 × 250
× 6mm) heat sink attached.
Heat sink dimensions:
10 × 10 × 0.25in (250 × 250 × 6mm): 0.1to 0.4kW
12 × 12 × 0.5in (300 × 300 × 12mm): 0.75 to 1.5 kW
