TT-423X Motors

The TT-423X motors were originally consequent pole motors. Today Callan Technology manufactures these motors as 6-pole, full complement motors, giving you the same electrical performance as the original TT-423X motors. They can be face or flange mounted and as standard are fitted with a TGF2030-147 tacho.

The TT-423X series DC servomotor-tach units extend the torque and power range of the TT-420X series. Utilizing high energy rare earth magnet material, the TT-423X series DC servo-motor-tach units provide precise motion control in machine tools, robotics, automatic material handling, wiredrawing, paper, plastic-film and foil processing, tension controls and packaging machinery, etc. Peak torque of up to 112 lb.ft gives ample power for fast, accurate positioning. Coupled with low motor inertia, theoretical acceleration of up to 6500 rad/sec2 results.

The unique permanent-magnet structure eliminates thermal runaway and commutation problems commonly encountered in conventional ceramic-magnet motors. Provision is made for mounting resolver, encoder or other position feedback devices by means of a spigot at the non-drive end with shaft extension. A 24V d.c. failsafe brake can optionally be provided. Motor power and tachogenerator leads are provided via junction boxes but alternative connection by flying lead (PG Glands) or connectors is possible.
