When the motor rotates, the particle in the center of the eccentric wheel is not in the center of the motor, which makes the motor constantly lose its balance and vibrate due to the action of inertia. The reason why the cell phone vibrates is that the motor makes it vibrate (1) caused by the eccentric rotation of the metal bar.
Coin vibration motors have a relatively high start voltage (compared to cylinder pager vibration motors) which must be considered in designs. Typically this is around 2.3v (all coin vibration motors have a nominal voltage of 3v), and failure to respect this could result in motors not starting when the application is lying in certain orientations.

A drive consisting two unbalance motors rotating in opposite directions generates a linear (straight line) vibratory movement. This type of motion is used when it is required to transport the material horizontally i.e. with vibrating conveyors, feeders or when it is necessary to control the feed rate by variable speed controllers.
A given motor speed change is associated with a given playback time interval; for the example in FIG. 4, for instance, the first change to a new vibrator motor speed occurs at time 0.7 sec, when the motor speed value changes from zero to 121, signaling a motor speed increase from zero to about 12.1% of full motor speed.
Stepper motor selection. Stepping angle: It is necessary to select the stepping angle of motor according to the requirements of load precision. The least resolution ratio of the load is generally converted to the motor shaft, pay attention to the angle for each resolution ratio and the stepping angle of motor should be equal to or smaller than the angle.In general, the stepping angle of 2 ...
