How to Test Mobile Phone Vibration Motor

A mobile phone vibration is created by a small motor called Vibra motor. when applied by a voltage or current it rotates and the vibration is generated by a small tiny piece of metal attach to its tip.

Checking this small piece of motor was so very easy just set the analog multi-tester range to X1 in resistance
 settings then connect the both probes to each terminals, polarity doesn't matter here for the motor will rotate clockwise if its in the right polarity. and rotates counter clockwise when not in each corresponding polarity.
A good and working vibration motor will then rotate and a bad or busted one will not.

    Does the mobile phone send constant 3V to the vibrator ? or does it send pulses. some where I read that i sends pulses and in that case wouldn't the vibrations be a bit intermittent ?
