10 tips for servos and steppers… a simple guide

What are the basic application differences between servos and steppers? Where would you choose one over the other? This short 10 point guide, offers a simple non technical explanation of the differences between these positioning technologies and attempts to de-mystify the subject, putting straight many misconceptions. By Nigel Dawson Edrives Product Manager nigel_dawson@festo.com

1. Torque comparison of steppers and servos Many people believe stepper motors do not have the torque capacity of servo motors. This is not necessarily true. The nominal torque of a stepper motor is very similar to a servo for a comparable frame size. Of course a servo has an additional time dependant peak toque rating and their speed curve is considerably more flexible and higher performance than a stepper. If a stepper solution is correctly sized, it offers a real low cost alternative to a servo.

2. Good applications for steppers Servo motors, despite many claims, are not always the best performance choice for applications. The structure of a stepper motor means that positions are discrete steps in its revolution cycle. If an application requires very good stand still stability, for instance positioning a vision system, a stepper will always be better than a servo. Servo motors resonate backwards and forwards at standstill, giving them their positioning characteristics; stepper motors stay very stable at standstill.

Positioning of vision systems is an ideal application for stepper motors

3. When is a servo not a servo? The term servo, often refers to a system with closed loop feedback, hence a servo motor is really only a servo when coupled to the drive to close the loop. This also means that any motor type can be built into a servo system to offer a cost optimised servo system. Such low cost servos utilise stepper

Are Wee Too Dependent on Computers

...Arguments about Computer dependency Since their invention, people far and wide have become increasingly dependent on computers. Computers have found their way into just about every aspect of our lives, and in most cases, they make things easier for us [4] . They allow us to work from home, socialize with our friends and family who live too far away to visit, and they provide an ever-welcome stress relief when we come home from school or work and just want to have some fun. But as we increasingly rely on computers to get through the day, the question begs to be asked: have we become too dependent on computers? Despite the many benefits of computers, there are also a number of arguments against them, one of which is the negative effect some believe they are having on children's education. Illiteracy is a growing issue, and many say that computers are to blame. In the past few years, many teachers have taken to shuffling their students off to a computer to type out short, quick assignments that could easily be written out by hand. While this isn't much of an issue for older students, it is an issue for the younger students who are just learning to read and write. Regardless of how much we're coming to rely on computers, printing and handwriting are a necessary skill to have. But typing out assignments has an effect on more than just the ability to print4. It can also negatively impact their spelling and grammar. While most programs now have spell- and grammar-check, they...

Dennis Baron's Essay 'How To Be A Woman Programmer'

...1. What is the major thesis of each essay? The thesis of Dennis Baron's essay titled "Facebook Multiplies Genders, but Offers Users the same Three Tired Pronouns" complies of the fact that Facebook has 58 different kinds of genders to choose from, yet the social media site only allows three pronouns: she, he, it. The thesis of "How to Be a 'Woman Programmer’" written by Ellen Ullman is the struggles of a woman becoming a computer programmer and enduring the sexual prejudice of man in the workplace. 2. How do their arguments differ? How are they similar? What are some of the major argumentative points each piece makes? The arguments differ in the way that Baron's essay was merely just nagging about not having more pronouns to identify others, while Ullman's argument is giving first hand stories and experiences to support her claims. The only thing similar about the arguments is that both essays are somewhat about gender issues. An argumentative point that Baron makes in her essay is that Facebook users can now identify as 58 different genders, but their friends can only wish him,l her, them a happy birthday. I love the point that Ullman makes when she states that when she was working as a computer programmer, women stood out in...
