Hush! Minimizing noise in electric linear motion systems

Under most circumstances electric linear motion systems are quiet.  They certainly don’t create the hissing and bang-bang noises associated with pneumatic systems. However, there’s another type of noise that comes with electric systems of all types – electrical noise or interference.

This is a common occurrence caused by random fluctuations in electrical signals. If the amplitude gets high enough, electrical noise can disrupt the operation of devices like electric linear actuators.  The results can be anything from erratic movements to complete system failure.

Electric high speed linear actuator reduces conveyor’s TCO

Higher production speeds usually translate into higher output volumes – a good thing in manufacturing. At least it’s good if product quality stays high and operating costs remain in line.  Machine designers are on the look-out for high speed linear actuators and other devices that can streamline processes.  But those high-speed solutions need to be reasonably priced and efficient to use.

Electric rod actuators add accuracy and repeatability to PCB manufacturing

Some manufacturing processes require high precision -- printed circuit boards (PCB) production, for example.  In these instances, the capabilities of each component in a production system are critical. Although machine designers know pneumatic cylinders well, these cylinders struggle to deliver the accuracy and repeatability demanded by high precision processes. Many design engineers now turn to electric rod actuators for accuracy and repeatability and for better operating efficiency.

Electric cylinders essential to advanced conveyor system [Case Study]

Conveying systems are common in manufacturing. They can be straight-forward systems that take packages from point A to point B or complex ones for sorting and diverting.  Systems used in food processing also must handle washdowns, a common practice in the industry.

As critical components, linear actuators must withstand the challenges of the application including environmental ones.  Pneumatic cylinders have been used extensively in conveying. However, electric cylinder use is growing, fueled by demand for programmability and better accuracy.

Electric rod actuator cleans up after hydraulics

Hydraulic cylinders are well-known linear motion workhorses in industrial machinery.   They’re reliable, familiar, capable of high force, and affordable, but they’re not without disadvantages. The leading ones are fluid leaks, large footprint (with hydraulic power unit or HPU), cumbersome changeovers due to lack of programmability, and high maintenance costs.

The introduction of electric high force linear actuators means machine designers now have a choice. An electric rod actuator can replace a hydraulic cylinder and eliminate the need to clean up leaks.

Solid-bearing, belt-driven linear actuator handles harsh environment

Many applications call for the carrying action of a rodless electromechanical actuator. And many of these need the high speed and long stroke capabilities of a belt-driven linear actuator. But what do you do when your application is in a dusty, harsh environment? Many rodless electromechanical actuators can’t handle these conditions. Their roller bearings get clogged with dust and stop working. Could a solid bearing be the solution?

Hygienic linear actuator keeps it clean

The world of food production and packaging is broad, varied and ever-changing. That world needs filling machines as diverse as the range of food products they process. Some filling machines have to handle powders and dry solids while others must handle thin or thick liquids. Some machines fill to a specified level, and some fill by volume or weight. This wide variety of equipment has a unifying need, though -- a need for hygienic design that can keep food products uncontaminated and withstand even the most stringent cleaning procedures.

Electric linear actuator fills accuracy need under harsh conditions

Volumetric filling applications of any type require high levels of accuracy and repeatability. If the filling operation is part of a food and beverage processing plant, there are additional important factors. Factors like food safety and the ability to withstand even caustic washdowns.

Filling equipment designers often rely on electric linear actuators for crucial motion control. Like the machines they’re a part of, these electric actuators need to deliver accuracy and repeatability and may need to stand up to a challenging industrial environment.

Electric linear actuator stands up to moisture, dust

Linear actuators used in sawmills are often subjected to dusty and wet conditions. If the right electric linear actuator isn’t specified, the component may fail and cause expensive downtime. Given the pressure to keep production costs down and output up, it’s essential to match the actuator to the manufacturing environment.

A good way to do this is to refer to a rating system. We use the IP (Ingress or International Protection) system because it evaluates ingress of both dry particles and moisture. An application where there is both dust and water spray needs electric linear actuators rated IP67 for a high degree of protection.

Integrated linear actuator increases manufacturing efficiency

Production cost and efficiency are important considerations in all manufacturing, but these factors take on critical status in some segments. Small-engine production is one of these.  Using the right linear actuator can boost efficiency and reduce cost.
