Some motion applications need axes to deliver both linear and rotary motion. Conventional designs for such functionality are often complicated and bulky. What’s more, rotary motors put to linear motion often have output shafts that are inadequate for supporting heavy side loads. Download the … [Read more...]
Satisfy application needs with versatile brushed dc and brushless dc motors
Brushed dc and brushless dc motors must be compatible with and satisfy critical motion-system parameters. These include the application voltage supply, overall footprint, target design life, continuous speed, and continuous torque requirements. Download the Ametek white paper... … [Read more...]
Noise and vibration in leadscrew-driven motion designs and how to avoid them
Leadscrews — especially those with high-accuracy threads — can be a low-vibration alternative to other linear-motion options. That’s in part because of the consistent contact between their load-bearing mating subcomponents. Download the white paper from Ametek … [Read more...]
Lead Screws 101 – A Basic Guide to Implementing a Lead Screw Assembly for Any Design
In many devices lead screw assemblies are used to convert motion from rotary to linear and vice versa. Historically these assemblies have had poor efficiencies and relied on grease for improved performance. Over the past few decades the advent of engineered polymers and new manufacturing … [Read more...]
Pressure Velocity and Leadscrew Assemblies
Pressure velocity (PV) is a fundamental property of all plastics, and is specific to the composition of the plastic. PV for a lead screw application is a calculated value based on load and surface speed of the interface between the leadscrew and nut. Manufacturers now have the ability to mold in … [Read more...]
