App note from Precision Microdrives experimenting on which is the best method to waterproof their vibration motors. Link here
We have mentioned some interesting vibration motor applications which may benefit from being waterproof or water resistant. For example, performance indicators for athletes, or stroke rehabilitation gloves would require regular cleaning. Naturally, the most convenient method for cleaning clothes and garments would be through a washing machine, and removing several vibration motors to do so, isn’t particularly pragmatic.
So we decided to look at some of our vibration motors and see if it would be possible to make them waterproof using fairly simple and easily implemented methods. This means that this Application Bulletin will differ slightly from our normal instalments which are full of industry best practices and advice. Instead, this is a more a report of an experimental/investigative process, in which we conclude with tips from our experiences, should you wish to try it yourself.
