Fig.14 Example of rotor vibration function and spectrum

Application of the Fourier transform to the analysis of vibration signals.

Andrei Shelkovenko. One of the developers and founder of Vibromera. The translation of the article may contain inaccuracies. Fourier transform and signal spectrum In many cases the task of obtaining (calculating) the spectrum of a signal is as follows. There is an ADC, which with sampling frequency Fd transforms continuous signal, which comes to its input during time T, into digital samples – N pieces. Then this array of samples is fed to some program (for example FourierScope) which outputs N/2 some numeric values. To check if the program works correctly, we form an array of samples as a sum Read more

Simple Balancing Stands for Rotors: Design and Application

Simple Balancing Stands for Rotors: Cost-Effective Tools for Precision Balancing Simple Balancing Stands for Rotors: Cost-Effective Tools for Precision Balancing Problem: Do you have machinery that shakes or vibrates due to imbalanced rotors? An unbalanced rotor can cause excessive vibration, leading to noise, wear, and even premature failure of bearings. This means more downtime and costly repairs. Ensuring rotors are properly balanced is crucial: it minimizes vibration, reduces bearing wear, and improves the equipment’s efficiency and lifespan. Solution: High-end dynamic balancing machines exist, but they are expensive and complex. Fortunately, there’s a simpler, low-cost solution. Simple balancing stands allow you Read more

Electric motors rotors balancing

The Issue: Balancing Rotors After Repair Enterprises specializing in electric motor repair often face a daunting task: achieving precise rotor balancing following the repair process. The implications of not balancing a rotor correctly are far-reaching, from escalated vibration levels to eventual mechanical failure. This article elaborates on a budget-friendly method that involves specialized balancing equipment and a straightforward stand design. Why Balancing Matters Balancing is far from a mere quality check; it’s an operational imperative. A rotor out of balance can result in: Heightened Vibration: Leading to accelerated degradation of motor components. Inflated Energy Use: Unbalanced motors consume extra energy, Read more

Assembled vacuum pumps rotors balancing.

Introduction At the factory, with our assistance, stands have been developed and implemented for the balancing of assembled rotors in high-speed vacuum pumps. These rotors must meet stringent quality requirements for balancing, adhering to the first-class standards as per GOST 22061-76, given that their operating frequency ranges from 42,000 to 60,000 RPM. Technological Process First Stage: At this stage, when the rotation speed of the rotor does not exceed 8,000 RPM and the rotor remains rigid, the primary components of its force and torque imbalances are compensated for. With our devices, a stable residual vibration level below 0.01 mm/s is Read more

Balanset-1 for coolers balancing

Coolers are an integral part of modern electronic devices, ranging from personal computers to specialized medical equipment. One of the key performance indicators for these coolers is their vibration and noise levels, which can directly affect the quality and reliability of the electronic equipment in which they are installed. Lower levels of vibration and noise are particularly crucial for medical equipment, where even the slightest imbalance can have significant implications. The Project Overview Recently, we received an order from a manufacturer of medical equipment to balance a batch of 100 coolers. This was a high-stakes assignment, given that the coolers Read more
