TORQUE TABLES WITH HOLLOW SHAFT
TORQUE TABLES WITH HOLLOW SHAFT
Torque tables series RSM -T-36-321-25-FS3
Glossary
for
torque motors
Construction
Torque table consist of torque synchronous motor with built-in radial-axial
(thrust) bearing, incremental sensor and hydraulic brake (optional).
Torque motor consist of a fixed primary coil unit (stator or primary part) and
rotated magnet ring (rotor or secondary part).
The stator is composed
of a coil unit that is encapsulated in thermally conductive epoxy.
The rotor consists of steel ring with glued permanent magnets.
The smoothness of movement is achieved by sinusoidal commutation of currents
in the coils.
Advantages
Absence of mechanical transmissions, high precision, repeatability and resolution,
no backlash, smooth movement, hollow shaft.
Applications
Machine tool, pick and place
machines, indexing tables,
semiconductor manufacturing.
