Rotary Servo Motors
Torque-Motor Speed Characteristics (200 V Models -30A to -1EA)
* Use an SGM7G-75A Servo Motor with a Holding Brake with an output torque of 14.4 N·m (30% of the rated torque) or
lower when using the Servo Motor in continuous operation at the maximum motor speed of 3,000 min-1.
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 Servo Motor can be used within the
intermittent duty zone.
4. If you use a Servo Motor 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.

Notes for the Servo Motor Ratings Tables
*1. These values are for operation in combination with a SERVOPACK when the temperature of the armature winding is
20°C. These are typical values.
*2. The rated torques are the continuous allowable torque values at a surrounding air temperature of 40°C with an alumi-
num or steel heat sink of the dimensions given in the table.
*3. This does not apply to the shaft opening. Protective structure specifications apply only when the special cable is used.
*4. Observe the following precautions if you use a Servo Motor with a Holding Brake.
• The holding brake cannot be used to stop the Servo Motor.
• The time required to release the brake and the time required to brake depend on which discharge circuit is used.
Confirm that the operation delay time is appropriate for the actual equipment.
• The 24-VDC power supply is not provided by Yaskawa.
*5. The allowable shaft loads are illustrated in the following figure. Design the mechanical system so that the thrust and
radial loads applied to the Servo Motor shaft end during operation do not exceed the values given in the table.
*6. This is the value if you combine the SGM7G-30A with the SGD7S-200A.
