| - | Shafted motors are ERM motors for which the eccentric mass is visible. When using shafted motors, it is important to ensure that nothing comes in contact with the eccentric mass while it is spinning. If this does occur, it could result in a large jerk instead of a smooth vibration, in addition to possibly damaging whatever came in contact with the eccentric mass.. | + | Shafted motors are ERM motors for which the eccentric mass is visible.

| Encapsulated cylindrical motors are similar to shafted motors, but they cover the rotating shaft in order to prevent interference of outside objects with the eccentric mass. | Encapsulated cylindrical motors are similar to shafted motors, but they cover the rotating shaft in order to prevent interference of outside objects with the eccentric mass. | ||
