Bench-top Pill Counting Instrument Mechanical Aid Hopper Vibration Kit

THE APPLICATION & SOLUTION Vibration is not only used for haptic feedback, and user interface notifications. In this example, our customer is a manufacturer of bench-top pill and tablet counters. Some parts of their machines were being upgraded to handle larger quantities of pill and tablets, and

When LRA’s don’t behave as expected (Part 1 of 2)

This blog post is part one of a 2-part series. Part one is a quick recap of how LRA’s work and how they are driven by dedicated driver ICs. Part 2 is about what happens when the LRA’s don’t work entirely as expected with selected

Visualising Voltage, Amplitude, and Frequency Relationships in 3D

We’re often stressing how a vibration motor’s voltage, vibration amplitude, and vibration frequency are interrelated – essentially the voltage controls the motor speed which in turn directly affects the frequency and amplitude, Application Bulletin 029 covers this in full. Other factors help determine the profile

AB-030 Released : Extending Vibration Theory – Displacement and Dissipation

Our latest Application Bulletin is aimed at extending our discussion of vibrations beyond the amplitude and frequency. Whilst both of these aspects have been covered in previous ABs, and in video form too, there is a large section in our product datasheets that we have not covered

Measuring Vibration Strength: A Quick Method

Introduction Just as with other components in your system it is important to profile vibration motors, in particular, to test its strength or frequency. Our specialised facilities allow us to quickly and easily run a variety of tests to fully analyse the performance of the motor

Understanding How Vibrations Are Transferred

So how does a vibration motor cause an entire object to vibrate? For eccentric rotating mass vibration motors, the unbalanced force created causes the motor to displace. The displacement is very small because the motor rotates so fast (the direction of the force changes as the

Why is Vibration Amplitude in G?

Those looking for the Quick Vibe Estimator will find the tool in AB-031: Vibration Motor Calculators – ERMs and LRAs Our vibration motors and linear resonant actuators use the unit G to describe their vibration amplitude. It leaves some of our customers with the question exactly what is G?

The Limits of Vibration Frequency for Miniature Vibration Motors

There are lots of interesting applications that require a specific vibration frequency. An exact frequency may be needed for different reasons, often it’s either a particular aspect of academic research or related to work with humans and the nervous system/skin. As a result, we are sometimes asked
