Rotating unbalance is the uneven distribution of mass around an axis of rotation. A rotating mass, or rotor, is said to be out of balance when its center...

vibration peak gives the angle at which the unbalance exists. Amount of unbalance and angle of unbalance give an unbalance vector. Calibration is performed by...

reference rotating with angular velocity ω is: F = m ω 2 r {\displaystyle F=m\omega ^{2}r} This fictitious force is often applied to rotating devices,...

reduce vibration by cancelling out unbalanced dynamic forces. The counter balance shafts have eccentric weights and rotate in opposite direction to each other...

impending aerodynamic stall. Eccentric rotating mass (ERM) vibrators work by rotating a deliberately unbalanced weight, so the weight is eccentric. Linear...
