*1. These values are for operation in combination with a SERVOPACK when the temperature of the armature wind-
ing 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 a
steel heat sink of the dimensions given in the table.
*3. 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.
F
Where F is the external force,
Thrust load = F + Load mass
Moment load = 0
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.
