FAST INDEXER SUPERTORQUE

SUPERTORQUE: A COMPLETE SOLUTION FOR FAST AND ACCURATE HANDLING OF SMALL PARTS AT HIGH RATES
Performance
High torque density, low inertia rare earth pm torque motor
Piping and cabling is fed through large center hole
Ultra stiff architecture allows 18 degree move + settling time in position with less than 4 arc sec error within 15 msec
With 20 stations (18 degree move) start stop rate can exceed 30 strokes/sec.
What
High accuracy and stiffness bearing system, tilting load capable
How it's made
Built in high resolution, high accuracy encoder on load side
Hollow stationary shaft:  only coupling flange is rotated
Where
Intended for application in fast rotary tables, handlers, positioners, where it provides all motion/control/support functions
Carousel or robot arm can be attached directly on motion flange
Stator can be fastened on outer frame or inner shaft
