* These items and torque-speed characteristics quoted in combination with an SGDB SER-
VOPACK at an armature winding temperature of 20°C.
Note These characteristics can be obtained when the following heat sinks (steel
plates) are used for cooling purposes:
Type 03AjB to 09AjB : 400¢400¢20 (mm) (15.75¢15.75¢0.79 (in))
Type 12AjB to 60AjB : 550¢550¢30 (mm) (21.65¢21.65¢1.18 (in))
