    Recently purchased a lot of ten vibration coin motors for the iPhone 4s. The part number on the motors is 1037s1 a151. Try as I might, I can't find any data on the voltage or amp load these can take. The seller didn't know either. I've already burned out two experimenting with numbers for "similar" motors, but any more and this could get costly.

    Do any of you much more experienced gadgeteers know how to find this info? I'd appreciate any help.

    Thanks,
    G

    Try 1.5V and increase the voltage slowly. These motors typically operate from 1.5V...3V

    Any thoughts on how many amps (probably mA)?

    A few mA only. Remember that these motors are menat to be operated by a cellphones's battery.

    these are not motors but LRA's

    iphone 4s and only phone 4s uses LRA's (liniar resonant actuactors) to generate vibrations, these require an ac voltage near its resonant freq, can be moved with an h brigdes as well...
