7.2.5
Torque-Motor Speed Characteristics
of the SGM7G-30 to -1E
*
If you operate the SGM7G-75A Servomotor (with holding brake) continuously at the maximum motor speed of
3,000 min
-1
, use an output torque of 14.4 N
m (30% of rated torque) or less.
Note: 1. These values are for operation in combination with a SERVOPACK when the temperature of the armature
winding is 100°C. These are typical values.
2. The characteristics in the intermittent duty zone depend on the power supply voltage.
3. If the effective torque is within the allowable range for the rated torque, the Servomotor can be used within
the intermittent duty zone.
4. If you use a Servomotor Main Circuit Cable that exceeds 20 m, the intermittent duty zone in the torque-
motor speed characteristics will become smaller because the voltage drop increases.
