Roller Screw versus Ball Screw Actuators
In the ever-evolving field of engineering, roller screw technology has become a significant force in linear electric actuator motion control....
STÖBER servo controls for SMS servo drives suitable for precise torque control, speed control and position control for demanding control tasks. Power range 0.45 to 45 kW.
Integrated Bus for:
Suitable for EnDAT encoder (single-turn and multi-turn) or resolver (with optional card REA5001).
Rated currents from 1.5 A to 50 A (peak 2.5-fold) with servo control.
Power supply servo inverter:
External 24V auxiliary power.
Optional CAN bus, Profibus DP, ProfiNET or EtherCAT.
Expandable with additional I/O cards for additional analog or digital inputs and outputs.
24V fail-safe brake control system.
Integrated filter and fan.
Including various applications such as:
Handling of 45,000 eggs per hour on a carousel which, through servo drives, rotates and with a lifting motion places the eggs in an egg braking machine.
Stöber servo motors are used for filling of syringes. IAI SCARA robots feed the syringes to the filling station. The servo motors are very precise, an absolute requirement with filling of pharmaceutical syringes. The SCARA robots are set so flexible, that sized parts are no longer required. All sizes syringes can be fille, without alternation.
Positioning heavy steel tubes up to 2 tons with manual control in any desired angle and height through five moveable axis. The five moveable axes provide a tilting motion, a rotary movement, an ingoing and outgoing sliding movement and a lifting movement.
Accurate and rapid exhaust ventilation valve control with EXLAR GSM and Tritex T2 servo actuator replacing air cylinders.
The Exlar actuators are fitted with stainless steel shaft and protection bellows.
The Tritex T2 actuators are equiped with embedded positioning controllers with 4-20mA control from the parent control.
The GSX actuators are controlled by Stober servo controllers.
ATB Automation provided in the engineering, programming and commissioning.
Adjustment mechanism in the steel industry. With the mechanism, the distance between the bloom (bar), and the distance meter is determined with which the position of the bloom was set at the supply track. Through the servo controller with Profibus this information is fed back to the PLC. The adjusting mechanism comprises a roller screw actuator FT Exlar with servo motor guided in Faro profiles and combirol bearings. The system is very robust.
Hexapod for stable positioning in which waves have to be compensated. Total mass 3000 kg, speeds of up to 1 m/s and accelerations of up to 6 m/s^2.
The system is made up of six pieces Exlar FT35 actuators with high capacity roller crew spindles with a lead of 20 mm and a stroke of 600 mm. The actuators are controlled by Stober EZ705 7.7 kW servo motorsin combination with 6 pieces SDS5022 servo controllers with ProfibusDP.
The axis of the Exlar actuator is chrome-plated and the end-shaft is made of stainless steel to prevent corrosion.
Mixers for the chemical industry driven by Stöber helical bevel geared motors and frequency inverters. Optionally available with an agitator driven by a compact servo motor.
The software engineers at ATB Automation assist in programming and commissioning via the help desk or on site
Besides control with I/O the drive can also be controlled with EtherCAT and ProfiNet.
The SD6 drive also has the CANopen option available.
We supply slewing ring bearings, oscillating mountings, tensioner devices from stock and we also have spiral bevel gearboxes, servo gears and electromechanical actuators in our delivery program.
In addition we also select and offer the right components and systems for motion control solutions, such as servo gear motors, linear servo actuators and complete XYZ cartesian systems.
