TORQUE TABLES WITH HOLLOW SHAFT

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.

Notes: 1. Peak current Ip is create peak torque Mp (2…3sec).
2. Maximal temperature of rotor 70°C.
3. The stator has built-in thermal sensor threshold type on temp 120 °C.
4. Maximal supply voltage is 600 VDC.
5.[GS/GT] - [values at Star/Triangle connection of phases.
6. Encoder output signal 1Vptp or RS422.
7. All data tolerance ±10%.
