The purpose of a Pager Motor is to vibrate the pager / cell phone as a signal to its user, either instead of or in addition to making some kind of tone / music / ring.

The vibrating is caused by a tiny rotary electrical motor, with an off-center weight attached to the drive shaft.

When it spins, like a washing machine with an off-center load, it shakes the cell phone or pager.
