AB-028 Released : Vibration Motor Comparison Guide

  • 24 February 2015
    • Different Types of Vibration Motor
Our latest Application Bulletin provides a quick reference for comparing different types of vibration actuators. We've included brushed ERMs, BLDC ERMs, and linear resonant actuators, discussing their most important differences. From driving techniques to vibration direction, or form factors to mounting advice. It draws from lots of our existing content, but houses it in a single place and emphasises the design decisions that set each type apart. All the differences are summarised in an easy access table at the…

VibroMat Application and Research

  • 3 February 2015
    • Full Colour; 8 bit Grayscale; 1 bit Grayscale
We’ve recently been in contact with one of our customers at the National ICT Institute of Australia (NICTA) who have been using our coin vibration motors in their research. The team is working on a project called VibroMat, which looks to present a “2D view of the world” using an array of vibration motors to users with visual impairment. In total 96 vibration motors are used to translate complex visual information into tactile information as a form of ‘sensory…

VAB-01 Introductory Gear Equations

  • 30 January 2015
    • VAB-01 Covers Compound Gears
We are pleased to announce we have recently completed our first Video Application Bulletin! It is based on the Application Bulletin 024 : Introductory Gear Equations, serving as a guide to the basics of gearing and spur gearchains. Aside from this blog post, you can also find the video on its Application Bulletin page or directly on Vimeo: VAB-01 : Introductory Gear Equations Precision Microdrives on Vimeo We'll be looking to create more Video Application Bulletins, we hope you…

Why Use 'Maximum' Start Voltages?

  • 22 December 2014
    • Start Voltage Example
You can use the voltage to adjust the speed of a motor, commonly with vibration motors this is used to vary the vibration amplitude. But just how low can the voltage be whilst ensuring the motor still operates? We previously included the Certified Start Voltage on our datasheets. This has since been updated in the Operational Specification to the 'Maximum Start Voltage'. This change has confused some customers who question why we have a 'maximum' value, instead of a…

New Haptic Feedback Evaluation Kit Tutorial: Vibration Alerts on External Actuators

  • 10 December 2014
    • Haptic Feedback Evaluation Kit external PWM connection
The external actuator pins Haptic Feedback Evaluation Kit is designed to provide a true a connection to the DRV2605 as possible. Unfortunately as a design trade-off, this means the MOSFET used to play vibration alerts is not accessible through the pins. We've recently written a new tutorial that discusses how to work around this limitation, so you can now build your own vibration alerts in Engineering Mode or Development Mode and play them on your chosen external actuator. The…
