Our ISO 18436-2РІР‚вЂњcertified specialists conduct residual imbalance analysis per DIN ISO 21940. We are an ISO 9001:2015РІР‚вЂњregistered company. Our customers use our measurement and calibration services to dynamically balance rotating equipment, helping ensure that it works efficiently and maximizes its life span. We specialize in providing preventative and predictive maintenance services to minimize the wear and tear that can result from excess machine vibration. Renown ElectricР’В has offered both on-site and in-house dynamic balancing services for over 30 years. Working With RenownР”В¬orrect balance and alignment of rotating parts are necessary to ensure optimal performance and long service life. A perfectly dynamically balanced body requires just the force supporting its weight to make it stay in place while rotating a dynamically unbalanced body in rotation requires external forces to counter the wobble from vibrations. In other words, dynamic balance can be thought of as the ability of an object to balance while in motion. If that is the case, the object will tend to vibrate while rotating even though it has no tendency to roll while stationary.

But the object can have dynamic imbalance even when it is statically balanced.

WhatРІР‚в„ўs the Difference?Р”Р„ rotating object must have static balance before it can have dynamic balance. When the effective mass center is at the axis of rotation, there are no residual centrifugal forces, and vibration is eliminated.

This process also tests vibration by adding or removing weight from the rotating body to align the effective mass center with the axis of rotation. Dynamic balancing is the method of measuring the imbalance with sensitive electronic equipment while a body rotates rapidly. Dynamic unbalance can be corrected with a 2 plane balance.Р”Р„symmetric mass distribution about the axis of rotation causes a rotating body to vibrate. As this state of unbalance can only be determined comprehensively when the component is rotating, it is referred to as dynamic unbalance. They differ in magnitude and do not have clearly defined angular positions. This can be expressed as 2 resultant unbalances acting in 2 arbitrary balance planes. Dynamic UnbalanceР”Р„ rotor will actually have an infinite number of imbalances distributed at random along its axis of rotation. Static unbalance can be corrected with a single plane balance. A rotating body at rest is in static balance if it continues to be at rest at all angular positions of its axis. But if the center of gravity is not on its axis of rotation, it tends to roll, and a braking force is necessary to keep it stationary. When an objectРІР‚в„ўs center of gravity is on its axis of rotation, it will remain stationary. Static balancing is necessary to prevent a stationary object from rolling. It is called static because it will be present even when the rotor is not spinning. It is equivalent to a single heavy spot in the rotor. Static unbalance is the simplest form of unbalance. Balancing will also improve the working environment of the machine operators by reducing noise, minimizing vibrations, and eliminating the risk of dangerous catastrophic failures. Static and dynamic balancing of motors and generators will make them run smoother and operate more efficiently for longer periods of time. Vibration can also cause structural fatigue stress, and excessive vibration can lead to dangerous operating conditions from unexpected catastrophic failures. Vibrations cause the machine to be noisy and reduce the life of its parts, especially the bearings. Reducing the vibration in your machinery relies on a number of factors, like a smooth rotating shaft, good bearing condition, and proper lubrication, but one of the most important ways to guarantee vibration-free operation is through symmetrical mass distribution.Р”Р„lthough designers strive to create machinery to be as symmetrical as possible, in practice, all rotating bodies have weight asymmetries about the axis of rotation, and this causes vibration.

Rotating parts in machines should be free of vibration to ensure their smooth operation and long service life.
