7.2.2 Small-Capacity, Coreless Servomotors: Ratings
7-6
7.2.2 Small-Capacity, Coreless 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 resistance, select hardware option specification 020 for the SERVOPACK.
However, you cannot externally connect dynamic brake resistance if you use the following SERVOPACKs (max-
imum applicable motor capacity: 400 W).
• SGD7S-R70A020 to -2R8A020
• SGD7W-1R6A20A020 to -2R8A20A020
• SGD7C-1R6AMAA020 to -2R8MAA020
*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.
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.
