What Causes Machinery Vibration?

The motor and shaft rotate around the axis of the shaft, which is supported by a bearing at each end. One key consideration in analyzing vibration is the direction of the vibrating force. In our electric motor, vibration can occur as a force applied in a radial direction (outward from the shaft) or in an axial direction (parallel to the shaft).
