* 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 05AjA to 13AjA : 400¢400¢20 (mm) (15.75¢15.75¢0.79 (in))
Type 20AjA to 75AjA : 550¢550¢30 (mm) (21.65¢21.65¢1.18 (in))
Type 1AAjA to 1EAjA: 650¢650¢35 (mm) (25.59¢25.59¢1.38 (in))
