Hi, Adam Ring with Innovative-IDM.  I wanted to take a few minutes and talk about the battle between the screw terminal and the cage clamp. So, why do people choose one or the other? Well, let’s just look at some of the basic facts. On the screw terminal, when you strip a wire and insert it into a screw terminal, the tightest that that’s ever going to be is the connection at the time you actually torque that screw driver down. From that point on it’s only ever going to get looser. Now when you talk about cage clamp terminal, when you strip the wire and insert it into the cage clamp, that’s actually the loosest that connection ever is. And as that wire then starts to take the shape of the terminal and the wires kind of splay out and basically mold to the shape of the terminal, it’s actually going to get tighter over time because of the spring force that’s holding that wire in place.

So, with temperature cycling as that wire has current running through it and it heats up and cools down and heats up and cools down, it’s going to be expanding and contracting and so forth. Well with the screw terminal, that’s only going to force that screw to back out and get looser and looser over time, whereas with the cage clamp with its spring technology, the spring actually compensates. As the wire expands, it expands, when the wire shrinks back it shrinks back with it and so it always maintains the right amount of tension on the wire for the application.

Now there’s also industrial applications; there’s typically a lot of vibration that is experienced. With a screw we all knows what happens when it’s around vibration, they tend to loosen up. With the cage clamp, vibration typically doesn’t matter. It moves and it adjusts and responds to the vibration without coming loose over time.

Now think about what it costs if you’re having to install hundreds of terminals in a given control panel. If you’re having to screw and tighten down each and every terminal, that’s going to take quite a bit of time. But with the cage clamp, all you basically do is insert a screwdriver, insert your wire, remove the screwdriver and it’s done. You get the same great connection every time. The other thing to consider is first thing in the morning when your fresh, you’re probably going to be tightening down those screws a lot tighter than the last one at the end of the day when you’re kind of tired. So you get a variation of how tight those wires are. And so then what ends up happening is once that panel gets installed in a machine, you’re going to start having loose connections and that’s going to potentially cause a machine to go down and cost you extra money.

So you always want to make sure that you use the right product for the right application. In the case where you have temperature cycling and vibration and you’re looking for the most efficient and best cost to connect your wires cage clamps are definitely the leg up.

Hi, I’m Adam Ring with Innovative- IDM. You know, when I walk through manufacturing plants sometimes I’ll come across a control panel – you open it up, look inside and you see this technology that is like 30, 40 years old. What’s starting to happen is, customers are finding that a lot of the controls in their automation are starting to really become aged. When that happens if something breaks it’s really, really hard to find. We find a lot of people who try and search on eBay to find replacement parts, sometimes they’ll send them in and try to get parts repaired, but as they continue to age the repair gets more and more expensive and eventually things just get to the point where they’re not repairable anymore. One of the worst things that happens is a major component necessary for the operation of a machine goes out and then the machine is completely rendered useless until you either find a new part or completely rebuild the controls for it. By retrofitting a control panel, you’re able to remove any of those obsolete components and replace them with the current up to date stuff that’s readily available. It gets rid of all of your hard to find really difficult parts; it enables you to not have to worry about repairs for a while.

Typically the life a new control panel, before you have to really start repairing stuff, usually it lasts about 10 years before they start to go breakdown and then you eliminate that big terrible major risk of down time. And everyone knows whatever the cost to build a new control panel is usually minimal in regards to or compared to what it costs if a machine goes down or can’t produce products for weeks or months on end while a new control panel is being designed and built.

So, overall it’s a really good idea if you’ve got aged control panels where a component going out could really, really cost some major downtime and production loss. It’s a good idea to go ahead and take a look at retrofitting those control panels.

5 Ways to Improve the Air Quality in a Pneumatic System

My name is Andy Lewis and I’m with Innovative-IDM. Today I’m going to talk to you a little bit about your air quality and your pneumatics system. A lot of my customers tend to have issues with debris in their airline, scaling from black iron pipe, water in their airline, leaks, etc. Pneumatic systems with compressors, primarily reciprocating compressors, cause the most issues. Now, how do you protect your machinery downstream? Your cylinder, your valves- how do you protect them from having to constantly replace them or rebuild them? Well there a couple of ways you can do it, and today I’m going to give you five ways you can do it.

First off, main line filtration. Basically this is going right after the compressor and the whole purpose of it is to get oil and water out of your system. What you are going to see is generally a larger filter than this, with a port size of one and three inches. It’s going to be a very large body and it’s going to be able to handle the oil that’s going to come through. Now what’s great about SMC versus its competitors is going to be the level of microns that they filter down to is much higher than other companies. For example, the average is about twenty micron filtration. SMC’s basic mainline filtration is anywhere between three and five microns. So what you’re receiving from that is better filtration.

Now, say for example you don’t have that filtration on your line, oil and water travels down the line. And say for example, it isn’t water yet- it’s still in vapor form because your reciprocating compressor is putting air out at 160˚ F. So you have vapor traveling down your line. As that vapor gets down your line, it’s going to turn into condensate, because it has hit the dew point and now it’s in droplet form. Your valves, your rubber seal valves are noticing this water- your cylinders are noticing this water. It takes more air, higher psi, to actually shift that spool or to move that cylinder. Why? Because rubber seals expand when they get wet. Alright, so how do you fix that? Well, one way you can do it is by using a filter regulator combo. With that being said you have your regulator at the top, you can actually pop it up, change, put in place, lock.

You also have your filter- standard is five micron, goes all the way down to .01 micron, instrument grade quality. There’s nothing in your system then, it’s completely clean dry air. After that there’s also an AMG. Now this isn’t an AMG but it’s the same size. It’s a water droplet separator and takes out 99% of all water that’s going to be in your airline, and that’s a point of use item.

Finally, if you find yourself with the reciprocating compressor instead of the screw type compressor, the air is abnormal, or much hotter than the screw type. And with that being said you’re going to want an after cooler and you’re going to want a refrigerated air dryer coming out of that airline before it hits your other machines.

How To Understand the Difference Between Servo & Stepper Systems

Hi, Adam Ring here and I’d like to talk a little bit about the differences between stepper motors and servo motors. There is a difference in the way they are structured and controlled. Stepper is typically 50 – 100 pole brushless motor where a servo is basically a 4 – 12 pole brushless motor. The stepper typically doesn’t have any kind of encoder for feedback, sometimes you can add it later on as an option where a servo is always built with some sort of feedback device whether it be an encoder or a resolver in order to tell its drive the position of its motor shaft.

Now if we take a look at the speed torque curve for each of these motors they’re very different. A stepper motor has a lot of torque at slower speeds. In fact quite a bit of holding torque because of so many pulls it can have a lot of holding torque at low speed and then the faster that you run, that torque actually starts to drop off. But you look at the speed torque curve of a servo motor it’s actually very, very flat and you get a constant torque regardless of what speed you’re traveling up until its maximum speed.

If we look at the amount of current that a particular motor draws, a stepper motor typically is going to draw full current whether it’s standing still or running. In some cases drives that you use with them may have a feature where you can reduce the current if they sit still for a long enough time, but other than that they are basically just drawing full current all of the time which also produces extra heating, as you can imagine. Servo motors on the other hand use the amount of current that’s required in order to get the motor to hold or move as demanded by the application. So typically they are going to run a lot cooler and they also have a neat little feature that enables them to produce on occasion 2 – 3 times their rated torque for short periods of time as a peak rating.

Let’s look at the cost of installing a stepper or a servo motor. As you can imagine, a stepper motor is typically going to cost less. The motor construction is simpler, you don’t typically have the feedback and the electronics to control the motor are typically simpler and less expensive. With a servo motor obviously they are going to have some type of feedback device built into the motor and then the drives that we use to control them typically are a little more involved when it comes to how they are designed and built and typically costs a little bit more.

A little bit about the application these might be used in: the stepper motor is used in applications requiring about 2000 rpm or less where you need a lot of torque at the low end, whereas a servo motor is typically used for your higher speed applications that are more dynamic and require more acceleration and deceleration typically 2000 rpm and higher.

So depending on whether you’re doing indexing moves with a light load or really dynamic moves with higher loads you can choose whether to use the stepper or the servo motor. Whether you’re in the market to purchase a stepper motor or a servo motor or not really sure which one is the best choice, visit innovativeidm.com we have an excellent knowledge center where you can come and research differences, catalogs, white papers, videos and learn more.

4 Reasons a Kitting Service Can Help You

Hi, I’m Adam Ring with Innovative-IDM and I wanted to talk to you a little bit about four reasons why customers are kitting these days. Primarily if you can order a kit, it is going to enable you to order one part number, from one vendor, that comes in one box and ultimately you will have one invoice to pay.

Now, let’s take a look at what might come inside of a kit. First of all, you will see there’s a quality control certificate that lists each item that is contained inside the box and you will also notice that it has two signatures. One from the person who pulled the kit, and another one who double checked it for accuracy.

Now imagine if you were to buy all these different components. They would probably come from different sources and obviously take multiple line items, on multiple orders, and then you would have to receive them in multiple boxes and then pay multiple bills. So all that can be condensed down to one part number, one order, from one source, with one bill to pay.

So, at the end of the day, wouldn’t it make sense to buy a kit from Innovative-IDM? After all, it is Home of the Legendary Customer Experience.

How To Pick an Industrial Motor

Hi, my name is Andy Lewis with Innovative-IDM and today I’m going to tell you about some guidelines whenever specing in or picking out an industrial motor. It’s really not as hard as you might think; it’s pretty simple to tell you the truth. But there are a couple of things that you need to pay attention to.

One, sizing:  whenever we’re talking about mounting size or voltage or current, we need to make sure that the holes are going to match up. You need to make sure that if it’s a 494T, that what you get is capable of handling that amount.

Second: current and voltage, as long as the application is not changing, need to be the same as the previous motor. If you’re unsure of that information, I would suggest that you take a look at the force requirements and other requirements from the application before you spec in that motor. First, take a look at torque curves; make sure that you’re providing enough information so that you can pick out the right size motor. Second is environment. Is it in a harsh environment? Are there pieces of rock, dust and dirt falling on it? Or is it inside? Or is it just for general purposes, running a fan 24/7 all day, every day.

Another idea is to take a look at whether it is inverter duty or general purpose. And when we say inverter duty, this type of motor is made for a high duty cycle environment; it is constantly speeding up and slowing down, all from an inverter or a VFD.

Next, there are a couple of different ways to control a motor. You can do it across the line, meaning that the motor is basically hooked up, three phased or one phased, however it is, to a circuit or a disconnect. Otherwise, you can use a VFD (Variable Frequency Drive) and use volts, hertz control, you can do open loop vector or you can do closed loop vector. The main thing you need to know here is that if you’re going to be dealing with closed looped vector for the most control out of that motor, you’re going to need an encoder or a tach for a DC motor to actually make that happen. Don’t overlook that; make sure that the mounting bracket on the backside is going to fit the encoder that you use.

Finally speed range. What speed are you working at? Do you need a gearbox? Do you need some type of rack and pinion? How do you plan on driving the end product? All questions that are very important, but if you do it correctly, it shouldn’t be that difficult.
