Some motion applications need axes to deliver both linear and rotary motion. Conventional designs for such functionality are often complicated and bulky. What’s more, rotary motors put to linear motion often have output shafts that are inadequate for supporting heavy side loads.

With trends towards miniaturization, precision, computer control and cost reduction, hybrid and can-stack style integrated stepper motor actuators are being used in an ever increasing range of applications. These precise, reliable actuators can be found in many applications including blood analyzers, robotic surgery, medical instrumentation, imaging equipment, valve control, X-Y tables, inspection and test equipment. This attractive technical solution eliminates the use of numerous components and the associated costs related to assembly, purchasing, inventory, etc. This white paper gives an overview of integrated step motor linear actuators and how to apply them to an application.
This white paper explains stand test methodology for generating force versus velocity curves and the benefits of adding acceleration and deceleration ramps. One of the first parameters that is considered when choosing a stepper motor based linear actuator for an application is how much force can the actuator produce. So naturally a speed versus force curve is the first place someone looks. There are a couple of different ways to present these speed vs. force curves, one is force versus pulse rate and the second is force versus linear velocity.  |

A common way to generate precise linear motion is to use an electric motor (rotary motion) and pair it with a leadscrew to generate a linear actuation system. Depending upon what this linear actuator interfaces with it can be constructed in a number of different ways. This white paper will explain the different style of leadscrew/nut based linear actuators and guide the user in selecting the right style for their application.

After sliding from its peak more than 25 years ago, U.S. manufacturing appears to be on the way back. Factory automation is a critical element enabling U.S. manufacturing companies to effectively compete in the global marketplace. To maintain this competitive trend, modern robotic and automation systems require higher precision and faster speeds than ever before.  |

| As demands for machine productivity increase, there is a growing interest in the use of fast-tool servos in motion control applications. These actuators have a very high bandwidth, but typically a very limited travel range. Examples include voice-coil motors, piezo crystals, laser galvanometers and magnetostrictive transducers.
Our latest application note describes Spectral Decomposition, a new strategy for pairing these fast tool servos with standard slow-tool servos. The result is a servo system that can deliver high-bandwidth performance without sacrificing range of travel.   |

Occasionally we receive calls from customers wanting to know why our size 17 hybrid linear actuator with an input wattage rating of 7 watts has better performance than our 46000 can stack version with an input rating of 10 watts? The answer to this is the efficiency of the motor itself. The average hybrid motor is about 65% efficient while the can stack actuators average about 25% efficiency. There are two primary reasons for these differences in efficiency. |
