The Motion Control Show
Welcome to The Motion Control Show hosted by Corey Foster, Application Engineering Manager at Valin. In each of the episodes below Corey explains various topics related to motion control and automation.
Episode 64:Linear motor actuators are great…but we hesitate before using them in vertical applications. We discuss why and what some solutions are.
Episode 57:Have you found an actuator that you like that you want but it just does not quite have everything that you need? Maybe you wish you could tweak it just a little bit?
Episode 54:Should you use 5 or 24-volt logic with your devices and controllers?
Episode 52:A useful topic to understand is the difference between “sinking” and “sourcing”. You can use this for inputs and outputs and to make sure that your feedback is compatible with your electronics.
Episode 51:Learn about different types, protocols, form factors and variations of feedback.
Episode 49:We take a broader, more philosophical, look at what feedback is, the types, and where to put it.
Episode 48:We discuss five questions that typically should arise when trying to select a drive for a motor.
Episode 47:We address the most common questions asked by customers who are not getting the performance they expect to from their servo motors.
Episode 46:The next step to understanding and solving performance problems that you may be having, like not getting enough torque or speed or burning up motors, is to understand the various thermal protection models that your drive and motor may have.
Episode 44:To size and select a servo motor, understanding the speed/torques is crucial. We discuss the basics as well as address typical questions that arise.
Episode 43:Piezo motors are an entirely different type of electric motor. We look at the basic structure and how they operate.
Episode 42:Linear motors are linear version of rotary motors…but typically are the same technology as brushless servo motors. We look at the basic structure of a few different designs.
Episode 41:Steppers motors are a specific type of synchronous electric motors. We look at the basic structure of them and what makes a stepper motor a stepper motor.
Episode 40:Brushless servo motors are a specific type of synchronous electric motors. We look at a few different designs and compare them.
Episode 38:Synchronizing the drive’s output current to the motor’s magnets.
Episode 37:We address the basics of what a drive is.
Episode 36:We address the basics of what an electric motor is.
Episode 30:For my 30th episode, I thought I'd celebrate by sharing a little bit of the goofs and fun and laughter and jokes and frustration that we've had along the way in making the first 29 episodes.
Episode 24:Valin’s Kent Martins shows what happens when important moment-loading information is omitted in Episode 24.
Episode 22:How do you mitigate your risks when sizing, selecting and designing mechanics? How do you decide whether to make or buy your mechanics? Here are some considerations. Learn more in episode 22.
Episode 21:You may be wondering about what problems adding feedback to your mechanics can cause. One is that it can make your electronics more sophisticated and therefore more expensive; the other one is that the feedback devices may not be as accurate as you think.
Episode 20:Do you embrace linear encoders, or do you avoid them whenever possible? Or are you wondering what a linear encoder even is? After all this sizing and selecting of mechanics, and even designing your own mechanics, you might be considering putting a feedback device on there and whether you should or not. Learn more in episode 20.
Episode 17:You cannot just start on the mechanics, pick the motors, pick the drives, pick the controls, pick the HMI. First you must understand everything all together. Since we're talking about mechanics, there's a few things we need to kind of jump on right off the bat. To figure out the holistic approach, there's a lot more to it.
Episode 16:When we size, select, and design gantry systems such as this one, we must make sure that we take into account the whole framing that this is going to be mounted on. Is that framing going to be simply supporting the actuators at just the ends? If so, we might get some deflection and vibration caused by the moving of the load or even just the weight of the actuator itself.
Episode 14:A very important factor to keep in mind when sizing your gantry system is the cable management and cable lengths you'll need. If you think about it, we're going to need cables to span throughout every axis of motion. Starting with the Theta, we must go through the Z-axis, through the Y-axis, and then even through our X-axis, to get to our end.
Episode 12:After taking a break from mechanics for a few episodes, we're returning to the idea of a gantry. But, you may wonder what a gantry looks like. For an explanation of that, we're going to turn to Valin’s own Michael Reynaud with a special animation by Valin’s Cassidy in order to show you what a gantry looks like.
Episode 11:I am continuing my conversation with you about EMC installation. We talked about electrical noise, where it comes from and how we control it. We talked about the reasons for Mains filters. Now I'm going to talk a little bit about how to select Mains filters and unfortunately, it's a real black art.
Episode 10:Continuing on talking about electrical noise, I often times have suggested mains filters to customers and they say, “Well I'm not shipping my system to Europe so I don't need it.” But there are very good reasons for putting a mains filter on your system even when you're not shipping it to Europe. Let's take a look at this.
Episode 7:Typically, when people think of rotary mechanics, they're talking about rotary tables. Here's a classic picture of a rotary table on the right. Now, this is a worm gear-driven table. So, you have to have an external motor. Here's the motor mount over here on the right-hand side.
Episode 6:We've been talking about a lot of different basic terminology. Now we're going to talk about just some basic types of linear mechanics.
Episode 5:We're continuing on with talking about some of the basic terminology and things you need to know in order to be able to size your own mechanics and gantry. We cover motion requirements and a summary at the end of the last several episodes.
Episode 3:Before we dive into the meat of the matter of sizing and selecting mechanics, there are some basic concepts we need to understand: namely the force, torque, moment, inertia, and axes of motion.
You were tireless in your support and it will not be forgotten!
When we needed technical assistance and applications support, Valin was there for us. Their knowledgeable engineers saved us an invaluable amount of time, helping us get up and running quickly. We are very happy with their services.
