What's the name of the part that's placed on axis of a motor that has weight off-center, to create vibrations? Say, phone vibration motors have that.

2Do you mean the weight itself, the eccentric rotating mass (ERM)?– user230Nov 21, 2014 at 19:51

1@snailboat is correct - the part is the eccentric rotating mass or ERM, although sometimes it is referred to as just the "eccentric mass" when the context makes it clear that it's part of a vibration motor.– ColleenVNov 21, 2014 at 21:31

@snailboat: Just the technical element with the mass. (without the motor).– SF.Nov 21, 2014 at 22:20

I believe ERM is the answer. Anyone up to posting it for easy +15 points?– SF.Nov 23, 2014 at 15:28

I believe you mean the eccentric rotating mass (ERM), sometimes called simply the "eccentric mass", as ColleenV notes in her comment.
