TGF 1810

Callan Technology manufactures a range of Tachogenerators to fit the TT series of Servomotors. The 4-pole frameless tachos, ranging in Voltage sensitivity from 3V/krpm to 57V/krpm, although many other voltage constants can be catered for.

The TGF1810 family of tacho generators are the standard models used in all TT-29XX (with exception of TT-293X) motors. They replace the TGF-1800 and TG 1801 models.

These tach armatures are secured to the motor shaft by compressing a cup washer and inserting a pin into the shaft which contacts with a V-groove in the armature hub.

Over the years many of the old types of Tachos were obsolete and replaced with the current manufactured models. The old tacho's can be easily identified by a black plastic brush holder assembly, compared to the grey metal brush holder assembly used on the current tacho models When replacing an old tacho with a new tacho all parts must change (i.e. tach armature, tach stator and tach brush ring assembly).
