Hello. I have a DIY vibrator project in mind, and I was wondering if we had access to any of the spec sheets for existing vibrators. I'm hoping to make a solid-state vibe, and need to know how fast I need to get the vibrating body moving. The hope is that it ends up bulky, but powerful.

Anyway, knowing the speeds (in Hz or RPM) of existing motor vibrators will help me with the circuit design and keep this at an intense but safe level.
