Top Tech Tip: Choosing between brush and brushless DC motors -- What are the tradeoffs?
Designing a system that involves motion and performs as intended requires choosing the right motor. The most fundamental decision involves commutation type. In some cases, mechanically commutated brush motors provide the best solution for the budget. In other cases, only brushless DC (BLDC) motors will do. Allied Motion provides a comprehensive review of the technology, along with tips and tricks for choosing the right solution for a given application.

Feel the difference: 2-shot injection molded knobs sample pack
In 1979, Rogan was the first knob company to mold a knob utilizing the 2-shot injection molding process, which uses a single plastic molding machine specially made to inject two materials sequentially or one on top of the other. If you've ever used a plastic toothbrush with a colorful rubber grip, it was likely 2-shot injection molded. Create a competitive advantage for your products. You can add markings, custom colors or graphics, and even glow-in-the-dark materials. Request a sample of control knobs or clamping knobs -- or both.

Very cool. Highly dynamic product sorting
Beckhoff's NCT (No Cable Technology) enables contactless power and data transmission to the company's XTS linear transport system mover. Products can be picked up dynamically from an unsorted and irregular product inflow and then stored in an orderly manner. A wide variety of movers turns XTS into a flexible multi-robot system that increases sorting performance while reducing the required installation space to a minimum.
