Specications, Ratings, and External Dimensions of SGM7F Servomotors

Ratings
*1. These values are for operation in combination with a SERVOPACK when the temperature of the armature wind-
ing is 100°C. The values for other items are at 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 a
steel heat sink of the dimensions given in the table.
*3. To externally connect dynamic brake resistor, select hardware option specification 020 for the SERVOPACK.
However, you cannot externally connect dynamic brake resistor if you use the following SERVOPACKs (maxi-
mum applicable motor capacity: 400 W).
• SGD7S-R70
A020 to -2R8A020
• SGD7W-1R6A20A020 to -2R8A20A020
• SGD7C-1R6AMAA020 to -2R8AMAA020
*4. The thrust loads and moment loads that are applied while a Servomotor is operating are roughly classified into
the following patterns. Design the machine so that the thrust loads or moment loads will not exceed the values
given in the table.
*5. If you use an SGD7S-7R6A SERVOPACK and SGM7F-35D Servomotor together, use this value (a derated
value).
Note: For the bearings used in these Servomotors, the loss depends on the bearing temperature. The amount of
heat loss is higher at low temperatures.
