What Is Rotor Balancing and Why Is It Essential?

Leave a Comment

Rotors are a critical component used to convert electric or electromagnetic energy into rotational motion. For rotors to operate reliably, they must maintain even weight distribution across the rotational axis. Too much weight on one side creates uneven mass distribution known as “unbalance”. Rotating parts in any mechanical assembly can become unbalanced. Uneven weight distribution […]

How To Avoid Major Causes of Unbalanced Parts

Leave a Comment

Unbalanced components can lead to electrical motor failures that necessitate costly investigation, repairs, or replacement. The easiest way to avoid this is to properly balance the rotor during the manufacturing stage. Unbalance happens when a rotating component’s center of mass, or inertia axis, becomes unaligned with its center of rotation, or geometric axis. It causes […]
