Ratings
*1. These values are for operation in combination with a SERVOPACK when the temperature of the armature winding is
100°C. The values for other items are at 20°C. These are typical values.
*2. The rated forces are the continuous allowable force values at a surrounding air temperature of 40°C with an aluminum
heat sink of the dimensions given in the following table.

*3. The unbalanced magnetic gap that results from the Moving Coil installation condition causes a magnetic attraction on
the Moving Coil.
*4. The value that is given is the magnetic attraction that is generated on one side of the Magnetic Way.
