Linear Motors

What are Sawyer motors and where are they used?

August 6, 2021 By Danielle Collins Leave a Comment

dual axis linear stepper motor

Originally named for Bruce Sawyer, who patented the design in 1968, Sawyer motors are a type of planar motor, and are sometimes referred to as “dual-axis linear stepper motors” since they use stepper motor technology and the moving part can travel in both the X and Y directions. Like other planar motor designs, Sawyer motors […]

New miniature linear voice coil motors from Moticont

January 22, 2021 By Miles Budimir Leave a Comment

voice coil linear motor

The new LVCM-010-013-01 linear voice coil motor from Moticont is only 0.375 in. (9.5 mm) in diameter and the length at mid-stroke is just 0.81 in. (20.7 mm) long. However, this new miniature voice coil motor has a high force-to-size ratio with a continuous force of 1.0 oz (0.28 N), a peak force of 3.2 […]

When do tubular linear motors outperform traditional iron core and ironless designs?

February 15, 2019 By Danielle Collins Leave a Comment

tubular linear motors

In a recent post, we looked at traditional iron core and ironless linear motors, both of which have a flat-type construction. But another type of linear motor, often referred to as a “tubular linear motor,” is also gaining traction in industrial applications. This is especially true in the packaging and medical industries, where tubular linear motors […]

3 things to consider when choosing a linear servo motor

February 8, 2019 By Danielle Collins Leave a Comment

linear motor

Direct drive linear servo motors have seen a measurable increase in adoption over the past several years, thanks in part to end users’ demands for higher throughput and better precision. And although linear motors are most often recognized for their ability to provide a combination of high speeds, long strokes, and excellent positioning accuracy that […]

How to specify motion components for cleanroom environments: Part 2

September 5, 2018 By Danielle Collins Leave a Comment

motion components for cleanroom

In this two-part article, we cover the products, materials, and features that designers and engineers should specify when choosing motion components for cleanroom environments. In part 1, we looked at how to reduce particle generation due to friction between moving components. In this second part, we’ll look at another source of contamination — outgassing — […]

How to specify motion components for cleanroom environments: Part 1

August 29, 2018 By Danielle Collins Leave a Comment

motion components for cleanroom

In this two-part article, we cover the products, materials, and features that designers and engineers should specify when choosing motion components for cleanroom environments. In part 1, we look at how to reduce particle generation due to friction between moving components. Designers of automation systems are tasked with many competing demands, such as balancing cost and performance, […]

Hybrid linear stepper motors: Operation and applications

September 27, 2017 By Danielle Collins Leave a Comment

hybrid linear stepper motors

Like servo motors, stepper motors are available in both rotary and linear designs. When an application requires force (rather than torque) output and can operate in open loop control, a linear stepper motor is often the preferred solution. Although linear stepper motors are available in both variable reluctance and hybrid designs, the more common version is […]

Five key electrical design concepts for mechanical engineers

March 11, 2016 By MCTips Staff Leave a Comment

clean-design-machine-longevity

Edited by: Paul J. Heney, Editorial Director Mechanical engineers often overlook important electrical issues when specifying their respective parts of an electromechanical system. This targeted advice will help you design your next electromechanical system. Mechatronic systems are the state-of-the-art technology in automation systems, intelligently integrating mechanical and electrical elements to perform increasingly complex and demanding […]

FAQ: What’s the difference between variable-reluctance linear and hybrid linear steppers?

July 21, 2015 By Zak Khan Leave a Comment

True Linear Stepper Motor

Linear motors come in different mechanical and electromechanical arrangements to satisfy the requirements of different applications. For example, brushless linear motors (capable of forces to 2,600 N or more) work well in heavy robotics or material-handing applications. Linear ac-induction motors output 2,000 N to satisfy heavy-conveyor parameters. In contrast, iron-core brushless linear motors deliver a […]
