Reduce Compressed Air Costs with Proper Air Cylinder Sizing

Choosing an air cylinder without a full understanding of how it will perform in a pneumatic circuit can have long lasting, costly consequences.

There may be no stronger ally of electrical power utilities than industrial size air compressors, as they drone on every day, taking atmospheric air and transforming it into useful energy. Countless kilowatt hours are gobbled up in a mechanical conversion of electrical power into pneumatic power, a process that is wickedly inefficient, with one horsepower of pneumatic energy costing six times as much to generate when compared to one horsepower of electrical energy. Nevertheless, with its tremendous versatility, efficiency, and widespread use throughout many sectors, compressed air provides a clean, reliable source of pneumatic power that has a value outweighing its cost to produce.

Energy Management Through Direct Drive Servo Technology

Inertia ratio provides a determinate measure for optimizing energy utilization of a servo motor during a machine’s design.

Direct drive servo motor and drive technology has many advantages. It reduces an axis’ parts count, mechanical losses, and often its objectionable noise. What’s more, it also increases the machine’s efficiency, lowering operation cost for the user due to its inertia ratio as compared to the more common mechanically advantaged multi-body axis designs. Reducing the mechanical transmission components (gearboxes, timing belts, pulleys, cams, lead screws, etc.) between the motor and its load is only part of the savings.

Smart Actuators Add Brains to Automation Brawn

Integrated electronics let smart actuators perform enhanced control functions that were previously external, such as switching, position feedback, and system diagnostics.

Actuators have always been on the frontline of automation, providing the “push and pull” that extends human capabilities to operate everything from delicate pick-and-place applications to 10-ton agricultural combines. Now, as the industrial world becomes increasingly digitized and connected, a new generation of actuators is fulfilling that role with more intelligence, simplicity, and economy, while overcoming increasingly challenging environmental conditions.

Eliminate Interference from Converter Output

Motor chokes, sine wave filters, and EMC sine wave filters can help suppress the electromagnetic interference at a frequency converter’s output.

Electromagnetic compatibility (EMC) in frequency converters can be very problematic if not addressed properly in the initial design. EMC ensures the proper operation of devices to avoid negative electromagnetic interference (EMI) effects. Good design takes into account the control, design, and function of each device to prevent such interference.

Sizing and Selecting Linear Motion Systems

The LOSTPED acronym can help designers avoid mistakes by reminding them to consider all the interrelated factors during system development and specification.

Virtually all manufacturing processes incorporate some type of linear motion. A common mistake that designers make when sizing and selecting linear motion systems is to overlook critical application requirements in the final system. This can lead to redesigns, and may also result in an over-engineered system that is costlier and less effective than desired. “LOSTPED” is a simple acronym that guides the designer in gathering the information needed to specify the appropriate linear motion components or modules in any given application.

Piezo Technology in Pneumatic Valves

Solenoid devices are the standard for electrically controlled pneumatic valves. However, piezo valves offer many advantages over their solenoid counterparts, and open entirely new areas of application.

Pneumatic valves made with piezo technology offer many advantages. They are small, lightweight, extremely precise, durable, fast, and save energy. Piezo valves do not need energy to maintain a switching status, and therefore generate almost no heat. What's more, piezo valves can potentially be operated without any noise. Another key advantage is that they always work proportionally.

Adding Simple Vision Systems to Collaborative Robots

Upfront evaluation can help determine if a vision system is the best solution for an automation application.

Adding vision to a collaborative robot can open a world of possibilities for automation applications. With a vision system, a robot can inspect parts, check specific features of a part, recognize a part to pick it up, count items, adjust its path using visual feedback, color sort, and so on. The breadth of applications requires careful consideration to ensure selection of the right technology for the job.

Shaping the Future of Service Robotics

Robots emerged in the early 1960s as a way to automate the monotonous and dangerous tasks in factories around the world. As time passed and new technologies emerged, these robots have taken a place outside of the industrial market and alongside humans in manufacturing and non-manufacturing applications alike.

How to Select a DC Motor: Coreless and Iron Core Brushed DC Motors

DC motors possess linear relationships that allow for very predictable operation. Motion control manufacturers and designers depend greatly on the premise that these linear relationships will hold true, since the laws of physics do not change. However, despite their simplicity, selecting a DC motor for an application can still be a daunting task. There are many other variables to take into account including dimensions, load, duty cycle, etc. This white paper provides an overview on Coreless / Brushed DC motors, and what to consider before committing.
