Intro to Vibratory & Haptic Motors: How They Work & Common Uses
By: Brad Proffitt, SM Magnetics Account Manager Vibration and haptic motors are the common means used to provide feedback from a signal or touch. The feedback is vibration. Vibration is an effective indicator that an action has responded from a software or hardware. These vibratory and haptics motors are in many items we utilize every day. Consumer electronics, Home appliances,...
FEA for Permanent Magnetic Circuit Simulations
By: Kevin Kurtz, VP, SM Magnetics Byline: A brief overview of terms and considerations when conducting and reading a static analysis of permanent magnets. When we discuss simulating a magnetic circuit, you’ll often hear the acronym FEA. This stands for Finite Element Analysis. It’s a common simulation method in many software packages for electro-magnetic fields, heat, and stress. It...
Designing & Manufacturing a Permanent Magnet Dipole Assembly
By: Michael Brand, President, SM Magnetics Designing and manufacturing a permanent magnet dipole assembly seems simple, however many variables are interconnected. Below are four (4) factors to consider, and as with most magnetic assemblies, these factors need to be considered together and not just individually. Gap Requirements A permanent magnet dipole assembly produces a very uniform magnetic field in...
From Concept to Production – Keeping Control In-House
By: Michael Brand, President, SM Magnetics Taking an idea or next generation design to market is a process. Going from concept to production requires many people, much research, futurist thinking, and money. But beyond that, it also takes trust in your manufacturing partners to control the process, information and IP. Finding the right magnetics partner is no exception when bringing...
Permanent Magnet Simulations
By: Michael Brand, President, SM Magnetics Today’s permanent magnet FEA and simulation modeling software is tremendous. They can help answer critical questions about motor performance, holding forces, flux density, sensor selection, and a host of other application requirements before any prototypes need to be made. There are many considerations that go into any design, so when using simulations as your...
