The test tube needs to go into the centrifuge, the component at its correction position, and the package onto the conveyor belt: gripping objects and placing them someplace else is a fundamental mechanical action in most work processes. In modern systems, “pick-and-place” is performed by automated grippers. They must be able to operate both powerfully…

Battery-powered motor applications need careful design work to match motor performance and power-consumption profiles to the battery type. Optimal motor and battery pairing relies on the selection of an efficient motor as well as a battery with the appropriate capacity, cost, size, maintainability, and discharge duration and curve. By Scott McMillan • Senior Applications Engineer […]

In a previous motion-sizing articles, we reviewed how to properly specify (using software) a ballscrew-driven motion axis. Then we reviewed how engineering teams can use a similar software-based approach for sizing rack-and-pinion-based servomotor-driven axes on the same five-axis gantry. Now we’ll explore the process for sizing the components (using that same software) for an electric-motor-powered […]

Modern servo drives with advanced tuning capabilities — when paired with performance servo motors having high-resolution feedback — can eliminate load-to-motor inertia-mismatch concerns. By the Kollmorgen engineering staff The accepted principle of matching motor to load inertia is no longer pertinent with today’s faster motion-control processors and advanced control algorithms. This outdated inertia-matching method of […]

From packaging to communications, BLDC servomotors are gaining market share in a variety of industries — and for good reason. They deliver high torque and smooth rotation (with minimal torque ripple) and lend themselves well to cost-saving customization. By Ralph Adams • President | Orbex Group Design engineers typically rely on off-the-shelf brushless dc (BLDC) […]

Disposable medical hand tools are seeing increased use due to their cost and hygiene benefits. Engineers who design these tools usually specify brush DC or brushless DC motors.

Edited by Mike Santora Optoacoustic tomography (OAT) is a technique for generating high-resolution images of biological tissue that scatters light waves, typically biological tissue. OAT systems create these images with pulses of dark red light that have a maximum duration of 50 nanoseconds. These pulses heat the tissue and cause it to expand launching ultrasound…
