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 Continue reading

VAB-02 : How Do Vibration Motors Work?

This VAB introduces how ERM vibration motors work, including how they create vibrations and what determines the vibration frequency and amplitude. It draws from our previous AB-004: Understanding ERM Vibration Motor Characteristics. These concepts are much easier to understand when you see everything in motion, so Continue reading

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 Continue reading

VAB-02 Released : How Do Vibration Motors Work?

Our latest Video Application Bulletin looks at how eccentric rotating mass vibration motors work. It’s the type of application that really lends itself to animation, where we’re able to show you exactly how the motor’s movement creates a displacement. We also discuss what aspects of the ERM affect the Continue reading
