their output. The gearheads used can carry heavy loads and require very little space. The modular approach used provides
plenty of scope when it comes to
designing our equipment." Thus, for instance, the micro drive system micro drive system - FAULHABER - DC Motors & Micro Drive Systems company uses the Series 2657 and 2224 bell-type armature motor with integrated encoder. The
highly Silent Running is Real Power dynamic ironless drive offers high performance in the smallest possible space. The graphite commutated motors of the
2657 Series, with a length of just 57 micro drive system mm and
a diameter of 26 mm, generate an
output of 47.9 W at 85% efficiency. Boasting a continuous torque of 44 mNm and a stall torque of 285 mNm, the 156g
drive is capable of setting in motion and stopping actuators weighing several kilos. The micro-sized precious metal commutated micro drive system drives of the 2224 Series offer an output capacity of 4.05 W at speeds of up to 8000 rpm, although it is just 24.2 mm long and has a diameter micro drive system of 22 mm. Depending on the model, the nominal operating voltage is 3, 6, 12, 18, 24 or 36 V micro drive system – i.e. there is a suitable voltage range for practically every application.
The speed and torque of both series can be adapted to the requirements by means of specially designed gearheads. micro drive system It is also possible to integrate encoders that are capable of creating up to 512 pulses per revolution. Tailor-made gears increase the resolution of the output significantly. This ensures that the exact position of the actuated system parts can be determined effectively. And yet, the units comprising motor, gearhead and encoder are so small that they can be integrated practically anywhere. This is complemented by a comprehensive range of power supply options.
The innovative solutions developed for analytical and diagnostic lab operations are a tribute to the interaction of expert knowledge in medical devices and micromotor expertise. Here, as in other areas, flexible solutions facilitate the automation of routine functions and free up human resources that can be deployed in other areas.
Precision cut with micro-step
Today, there are many methods of surgery, covering the whole body from head to toe. Eye surgery has now become a standard operation. State-of-the-art technologies, such as laser equipment, have become widespread. All the instruments and apparatus have to be precise and reliable.
A surgical instrument is placed precisely over the eyeball with the aid of a controlled vacuum, and an incision is made in the uppermost layer of the cornea. The resulting circular flap is not detached completely. It remains firmly connected to the cornea, like a hinge. Then the flap is folded to one side; the operating field has now been prepared. This intervention serves to prepare for corrective surgery to restore eyesight and remedy other vision defects using laser beams. The precision cut is performed by the Amadeus™ Microkeratome made by SIS. With precision the blade is moved forward and back by the ARSAPE 2-phase stepping motor with planetary gearhead. A FAULHABER brushless DC motor causes the blade to oscillate simultaneously. For patients the
