Until recently, purchasing drives, motors, and cables from different suppliers was routine. The technology simplified the process of choosing the cables, and any installation technician was capable of choosing cables that met a specific application’s needs and installing them without causing any critical issues in the system.
There are several considerations when selecting a direct drive linear actuator for a specific application, such as the required speed, force, motion profile, available physical envelope, and environmental factors. This means the chosen actuator solution must produce the load force and speed requirements, fit in the available space, and perform as required under the subjected environmental conditions of the application.
Amplitude gain margin is a measurement in the frequency domain, taken from a Bode plot, that takes the amplitude below 0 dB at the lowest frequency point that the phase reaches -180 degrees (phase crossover frequency).
So, you’re beginning to size a new servo motor and drive for an application. How do you go about doing this? Sizing tools can be highly beneficial for achieving optimized products. However, one needs to pay attention to the warnings and information provided in sizing systems.
A collaborative robot (Cobot) is a robot intended to physically interact with humans in a shared workspace. This is in contrast with other robots, designed to operate autonomously. A "cobot" is a robot that works in tandem with a human worker. The assumption is that a cobot and a human can produce an end result better and faster than either could do working alone.
Frameless, or “servo motor kits”, open up numerous possibilities in designing motion elements for your machine related to performance. A frameless motor consists of rotor and stator components which are built into a machine assembly to transmit torque to a load. Many applications which take advantage of a frameless motor are direct driven, which eliminates bandwidth robbing compliance. Effectively, this means you have eliminated torsional losses and any wind-up or spring losses.
A collaborative robot (or Cobot) is a robot that is made to work with or interact with human co-workers. For most of us normal folks, the most well-known example is Tony Stark’s robotic arm. (For those reading who are wondering why I don’t refer to the arm as JARVIS, it’s because JARVIS is the AI and controls other things but not the robotic arm.) Tony has bit of an unhealthy relationship with the robotic arm, he insults it, puts it in a dunce cap, puts it in time out, or threatens to dismantle it. At which point the robotic arm usually hangs his robotic limb downward into sadness. But, the robotic arm is there to do work for Tony in his basement. He may have a large house, but he doesn’t want a 10-foot-tall robot behind a fence. He wants an assistant, a co-worker of sorts that can help build his Iron Man suits.
Robots and automated machines and vehicles form an integral part of our everyday lives and are not just found in the industrial sector: precise control of motion is indispensable. The combination of the two areas of technology – motion (servo drives) and movement (AGVs) – allows KOLLMORGEN to play a leading role in “Motion in Movement – 4.0 Ready” solutions, and to offer its own customers complete and integrated systems, ready for Industry 4.0.
