Introduction to the Stepper Motor Linear Actuator Attachment

6:30

The popularity of micro linear actuators has been steadily increasing, driven by the need to increase productivity in confined spaces.Â To help meet the demand of the miniaturization trend, Oriental Motor has developed a compact linear actuator that can be attached to an off-the-shelf stepper motor.

According to Verified Market Reports, "The Micro Linear Actuators Market Size was valued at USD 1.50 Billion in 2023 and is expected to reach USD 4.20 Billion by the end of 2030, with a CAGR of 15.85% during the forecast period 2023-2030."

Claude 3.5 Sonnet says, "The US micro linear actuators market could potentially see a compound annual growth rate (CAGR) of approximately 9-11% over the next decade. This would translate to a total growth of about 140-180% over the 10-year period."

This growth is anticipated to be driven by increasing adoption in medical and healthcare, industrial automation and robotics, consumer electronics, automotive (electric and autonomous vehicles), and aerospace/defense industries.

What is the Stepper Motor Linear Actuator Attachment?

The Stepper Motor Linear Actuator Attachment is a mounting adapter that includes a lead screw and a resin nut with high wear resistance.Â It can be easily attached to off-the-shelf stepper motors, like a gearhead, and converts rotary stepper motion to precise linear motion (similar to an external type stepper motor linear actuator).

In this example, we show the Stepper Motor Linear Actuator Attachment by itself and a finished assembly with a PKP Series 42 mm frame size stepper motor.

With a built-in axial bearing mechanism, the Stepper Motor Linear Actuator Attachment can handle up to 100 N (with a 42 mm frame size stepper motor), and axial loads can be applied directly.Â

The actuator can also provide an equivalent holding force to hold the load in place when power is removed or fails.

Installation

Since the Stepper Motor Linear Actuator Attachment does not include an anti-spin mechanism, it must be provided by the customer.Â Without it, the nut will just spin in place and won't move anywhere.Â In the image below, we show an example of a finished assembly of a Stepper Motor Linear Actuator Attachment, an anti-spin mechanism, support bearings, and a linear guide.Â The product does not include limit switches or sensors, so they will have to be installed elsewhere, such as on the linear guide.

What Makes it Unique?

The Stepper Motor Linear Actuator Attachment can be installed to a stepper motor output shaft without a coupling mechanism, which reduces the number of required components for assembly, saves space, and speeds up design compared to custom-built linear actuators.Â

In the example below, the number of components is reduced from 9 to 6 as we were able to eliminate the coupling, fixed-side bearing, fixed-side block, and a standalone leadscrew.

Introducing The Stepper Motor Linear Actuator Attachment

At this time, the Stepper Motor Linear Actuator Attachment is offered for stepper motors in the 42 mm and 30 mm frame sizes with stroke lengths from 30~300 mm, up to 10 kg of transportable mass (or 100 N thrust), and speeds up to 180 mm/s. Â The repetitive positioning accuracy is +/-0.05mm.

Compatible Lineup

Various types of PKP Series high torque stepper motors and CVD Series bipolar microstepping drivers can be combined to build different types of stepper motor linear actuators.Â In the diagram below, we show the combinations that's possible with our extensive product lineup.
