  • Critical Speeds of Rotating Shafts and Mass Review

    The rotational velocity at which the vibration increases dramatically is called the quot;critical speed of the rotating mass. This characteristic for a shaft mounted mass is called quot;settling of the wheelquot;. The settling is at the velocity the axis of rotation and the shaft or mass begin to rotate around an axis through their center of gravity.

    A vibrating motor is essentially a motor that is improperly balanced. In other words, there is an off centered weight attached to the motor's rotational shaft that causes the motor to wobble. The amount of wobble can be changed by the amount of weight that you attach, the weight's distance from the shaft, and the speed at which the motor spins.
