Lifetime of DC Vibration Motors (MTTF & FIT) AB-019 Released

Vibration motor failure rate can be modelled by the 'Bathtub' Curve

Most questions we are asked are answered somewhere in our datasheets or on the website, and we’re more than happy to help our customers with all the information you need. Unfortunately, the answer to one of the most common questions is not to be found.

“How long do your motors last?”

We have provided estimates based on our experience in the past, however we’ve never been able to offer statistical analysis. Until now!

We’ve dropped hints in previous articles and Application Bulletins that we’re working hard to test the longevity of our motors, and we will slowly be publishing our findings throughout our product catalogue. This is a significant development because nobody has looked at the Mean Time To Failure or Failure In Time Rates of miniature DC vibration motors before.

In the meantime we’ve documented how we are testing the motors, and what the numbers mean. To find our more, try the link below:
