What are the basics of power supply mechanics to voltage and RPM's in micro vibration motors? Answered
I'm trying to make several different versions of vibrating plush toys so I can find out what the ideal vibrating feeling will be for toddlers and babies. Too high an RPM can be scary to a little kid.
I'm a beginner with little/no knowledge of basic electronics, but a capable tinker and solderer. I'd like to understand the basic logic of power supplies to micro motors and how to arrange the basic wiring. I've seen lots of instructibles but I can't find a simple explanation of this kind of thing.
I've got a Radio Shack 3VDC vibe motor. no-load speed is 16K RPM. I tried wiring it to a two-AA battery enclosure (2x1.5V=3V?) and it wouldn't run. Touched leads to a 9V and it powered up but RPMs are way too high.
Some related questions:
1. Can you vary the voltage to a typical micro motor and get different RPM's?
2. What's no-load speed and do I need to worry about it?
3. What kind of switch can I use to power on/off
4. How do you tell what kind of battery config to use with a motor
