* 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 (alumnium
plates) are used for cooling purposes:
Type 10AjA to 20AjA : 300¢300¢12 (mm) (11.81¢11.81¢0.47 (in))
