mechanical scanning, the ALO head (Adaptive Laser Optics) offers further advantages. The integrated laser head performs fine adjustments to the weld seam itself. Instead of operating the control of the entire welding process via the
welding robot, as in the conventional flat motors flat motors - FAULHABER - DC Motors & Micro Drive Systems method,
the new procedure allows much faster adjustments. The robot welding arm only predetermines the Flat Motors rough direction. The laser head control
itself then performs the process of fine adjustment and tolerance equalisation on the seam in the range of
+ flat motors 5 mm. In order to obtain exact, reproducible results,
scansonic is currently collaborating with the micromotor
manufacturer FAULHABER. The requisite wire pressure is ensured by a sinusoidal motor with matching gearhead. This permits rapid and highly sensitive tracking of
the entire laser head. The motor torque is evaluated, giving the flat motors dimension for the pressure. The sinusoidal motor with integrated motion controller allows precise detection of the motor current; accurate measurement is as easy as ABC. With this pressure control, the flat motors weld seam can be recorded in 2D in the x- and y-direction, and tracked precisely.
Tracking in the z-axis is undertaken flat motors by a telescopic arm with integrated path sensor. In combination with the tracked filler wire, this produces optimal, (laser) point-accurate tracking of the welding focal point exactly along the joint flat motors edge. As the head is capable of eliminating minor deviations itself, the robot control can be permanently set to the rough seam course. Set-up and programming of new welding heads take just a few hours, depending on the task.
Accurately positioned and evaluated
The FAULHABER sinusoidal motor is perfectly suited to this application. The extremely compact shape with integrated "piggy-back" motion controller is particularly conducive to a small, light-weight head design. The user-friendly "Motion Manager" software facilitates coordination with the respective welding parameters. Sensitive evaluation of the motor operating data is necessary for this purpose. Via the integrated control electronics, the drive current of the motor is determined and evaluated accordingly. In addition, the integrated analogue Hall sensors enable position detection. The necessary control signal for the laser head is thus calculated from position and current detection. As the motor is based on a highly dynamic design, readjustment can be performed very quickly in the event of deviations from the input values. The weld seam remains exactly on the "leading" joint edge of the sheets. The sinusoidal motor transmits the data to the control via RS 232 interface.
The new control system is characterised by optimal position determination at the exact welding focal point – with minimal effort. State-of-the-art FAULHABER technology made a valuable contribution to the success of this project.

Reliable Drive Solution for Flying Probe Systems
Compact, brushless DC Servo motors in operation
In the case of automatic test facilities for electronic circuits, it is becoming increasingly difficult to justify the use of conventional needle-bed adapters. High packing density in conjunction with increasingly short product life cycles often make it impossible to recoup the initial adapter-specific investment. The alternative is the so-called flying probe system, in
