What are Rigid Rotors?

Rigid rotors are rotating parts that do not exhibit flexibility at operating speeds, meaning they do not change shape. These rotors operate stably because their operating speeds remain below their natural resonant frequencies. Unlike flexible rotors, the unbalance occurring in a rigid rotor remains constant regardless of rotational speed. This allows balancing to be performed at a single speed, eliminating unbalance across the rotor's entire operating range. This feature makes them ideal for many industrial applications, such as pumps, motors, and fans operating at low and medium speeds. The stable structure of rigid rotors simplifies the dynamic balancing process and ensures more reliable results.

Rigid rotors are excellent candidates for single-plane or two-plane balancing operations. At MBS Balans Sanayi, we offer balancing machines that can correct unbalances in these types of rotors with high precision. Balancing a rigid rotor is typically accomplished by measuring the mass distribution imbalance at the mounting position and adding or removing appropriate correction weights. This process minimizes vibration and noise while increasing the machine's overall efficiency, bearing life, and operational reliability. This stable structure of the rigid rotors reduces maintenance costs and the risk of failure.
