Choosing the best linear actuator based on manufacturers’ specs

Source:  Tolomatic Blog.  Originally posted by Gary Rosengren on Tue, Apr 22, 2014 @ 08:39 AM

Motion system designers often need to evaluate competing components to select the best one for an application.  For linear actuators and other motion system components, the decision generally comes down to which product will provide the longest service life given the specifications of the project.

Manufacturers give you performance data which can serve as guidelines for component ball screw linear actuatorselection and use.  Keep in mind, though, this information is for the individual component only and may not relate directly to the configuration and conditions of your application.

When you’re comparing data from different manufacturers, be sure you’re comparing apples to apples.  For linear actuators you may need to normalize the data of all the rolling elements (such as the ball screw or roller screw) as well as the linear bearing components in the system to the same Basic Rating Life (L10)

Basic Rating Life

International standards define life for individual ball or roller screws as the number of revolutions the shaft makes in relation to the ball nut body before the first evidence of fatigue develops in the load bearing raceways of the screw shaft, nut body, balls or rollers. For linear ball bearing systems life is defined as the linear distance traveled by a system before the first evidence of fatigue develops in the linear bearing rails.

Basic rating life (L10) for ball or roller screws for an individual screw or group of apparently identical ball/roller screws operating under the same conditions is the life associated with a 90% probability of achieving the nominal life (1,000,000 revolutions.) For linear bearing systems, basic rating life (L10) is expressed in linear units (100,000 meters of travel).

The standardized life equation for ball/roller screws is:

L10 = (C/P)3 x 1,000,000, where

         L10 = basic rating life in revolutions

C = dynamic load rating

P = application load

The standardized life equation for linear bearing systems is:

L10 = (C/P)3 x 100,000, where

         L10 = basic rating life in meters of travel

C = dynamic load rating

P = application load

These equations show the fundamental relationship between load and life. When the load on any given load bearing component is reduced by half, the life is eight (8) times longer. Inversely, increasing the load by 50% reduces the expectation to about 30% of life.

A Real-Life Example

Consider this example of evaluating linear bearing capability. You need to determine which actuator is more robust and best suited for an application. Manufacturer “A” (in red on the chart) has a maximum load capacity of 3,080 N (692.4 lbs.) while manufacturer “B” (in blue) has a maximum capacity of 1,996 N (448.7 lbs.)

In this first chart (on right) it looks like “A” is the winner, doesn’t it?linear actuator specs

But consider this. Manufacturers specify the linear distance or number of revolutions to which their ratings apply. So load ratings are based on the rolling elements’ specified L10 travel distance.

In our example manufacturer “A” has a Basic Rating Life of 600 Km while manufacturer “B” has a Basic Rating Life of 5000 Km. When Basic Rating life is normalized to 600 Km, this linear actuator specssecond chart (on left) tells a different story. Because the product from manufacturer “B” is able to carry the load for a longer distance, manufacturer “B” wins.

Normalizing the manufacturers’ data is a critical step in comparing performance data. It can lead to important discoveries.

Stepper Motor Linear Actuators 101

What exactly is a Stepper Motor Based Linear Actuator?

Need to know how a Stepper Motor Linear Actuator works?

Suppose you, as an engineer, are tasked to design a machine or part of a machine that requires precise linear positioning.   How would you go about accomplishing this?  What is the most straightforward and effective method?

Haydon Kerk Stepper Motor Linear Actuator White Paper

Haydon Kerk Stepper Motor Linear Actuator White Paper

When students are trained in classic mechanical engineering, they are taught to construct a system using conventional mechanical components to convert rotary into linear motion.   Converting rotary to linear motion can be accomplished by several mechanical means using a motor, rack and pinion, belt and pulley, and other mechanical linkages.   The most effective way to accomplish this rotary to linear motion, however, is within the motor itself.

This White Paper, from Haydon Kerk Motion Solutions, discusses the technology behind stepper motor linear actuators, what makes them different, and concludes with a detailed example illustrating how they should be sized to move a given load.   Click on the link below to download it.

Maximize reliability and performance of actuator drive systems by minimizing electrical noise

A New White Paper from Tolomatic .  Published January 28, 2014

Is your actuator drive system subjected to harsh factory conditions that include dust, moisture, heat or vibration?  If so, then chances are electrical noise is the culprit that can disrupt actuator signal controls, cause erratic motion, or in some cases, complete system failure if left unchecked.

Although system noise can never be completely eliminated, Tolomatic’s new white paper  will help you identify and minimize the causes of electrical noise in drive systems to increase system performance.

This white paper will cover:

  • What causes ground loops and how to mitigate ground loop noise
  • The common causes of electromagnetic interference (EMI) and how to minimize the effects with proper switching and cabling practices
  • Best practices for reducing the risk of communication outages and preventing network storms

Maxon Precision Motors offers a product for converting rotary motion into powerful linear motion.  The GP16 precision spindle combined with a DC motor make it possible to transform rotary motion into axial motion.  Gearheads, motors, encoders and controllers from maxon’s standard program are used to drive the spindles.

Maxon GP16 Spindle DC Servo Gearmotor

Maxon GP16 Spindle DC Servo Gearmotor

Available in a metric M6 spindle with a self-locking function or a 5mm ball screw which offers high efficiency, high load capacity and no self-locking feature.  A central component is the axial bearing, which must withstand the high tractive and compressive forces of the spindle.

For the planetary gearhead, 14 different reduction ratios are available, from 4.4 up to 850:1.  Depending on the reduction ratio and the type of spindle, this makes it possible to achieve feed forces between 35 and 370 N and even up to 400 N for short durations.
Nine different brushed and brushless motors may be used to drive the system.  These motors may also be equipped with compatible sensors (encoders), which are essential for precise positioning. EPOS positioning controllers are recommended for controlling the motor-sensor combination.  These controllers feature a wide range of functions as well as CANopen or EtherCat.
maxon motor’s expertise in drive technology is reflected in the entire selection of components.  The spindle drives feature robustness, flawless operation and a long service life.

Small Spindle Drives from maxon motor are now available in Wear-proof Ceramic

Two new complete systems composed of spindle, axial bearing, and gearhead are new from maxon motor.  With the GP8S and GP16S spindle drives, maxon motor is expanding the program and simultaneously launching the ceramic spindle.  The ceramic spindle is an extraordinary product, with several advantages.

The GP 16 S with ceramic spindle joins the ranks of the existing 16 series spindle drives.  With its unique metric M6 ceramic spindle, it transmits up to 315 N in short-term operation.  These axial forces are compensated by axial ball bearings in the gearhead’s output stage.  The variety of reduction ratios possible in the integrated planetary gearhead makes the spindle drive suitable for highly dynamic applications such as focusing systems or valve and flap adjustment.

The small 8 mm GP 8 S spindle drives come standard equipped with metric steel spindles or ceramic spindles.  The M3 x 0.5 mm spindle is designed for feed forces of up to 32 N in short-term operation.  Two pre-loaded ball bearings serve as the axial bearing.  Due to the extremely compact design, the GP 8 S spindle drives achieve a very high force/volume ratio, a characteristic highly desirable for collimators, dosing pumps, and many other applications.

Spindles made of high-tech ceramic – better than steel!

Maxon ball screws made of zirconium dioxide (ZrO2), a high-performance ceramic, feature many advantages over conventional steel spindles or expensive ball screws, advantages that can be critical for your application.  For instance, the ceramic spindle has nearly negligible slip-stick effect, so start up is smooth and free of jerking.  Due to the outstanding sliding characteristics and the high wear-resistance of the ceramic spindle, it’s possible to achieve high speeds and also allows for highly dynamic, precise movements.  The life span of the ceramic spindle is several times that of steel spindles, assuming that a suitable threaded nut is selected.

Ceramic spindles can be used in high-temperature applications, as well as in magnetically inductive environments.  For example, a ceramic spindle will not interfere with the magnetic field in an MRI scanner.

The biocompatibility of the material makes ceramic spindles of particular interest for medical engineering.
