Abstract
A low-profile motor arrangement for accomodation in a low-volume electronic device such as a radio pager. The motor is designed to provide a vibrating action for silent alerting that does not require any additional add-on parts, but effects the required vibrator action by a designed-in unbalance in the rotating internal parts.
