・Motor Shipping Inspection
We support the transition from conventional sensory inspections—such as operator-based listening checks—to automated inspection systems. By measuring motor vibration and abnormal sounds, our solution enables pass/fail judgment and can also detect internal bearing abnormalities.

・Vibration Monitoring of Motors and Pumps
By continuously monitoring motors installed in equipment, our system helps accurately determine optimal timing for parts replacement, supporting more efficient maintenance and reduced downtime. It also plays a key role in preventing unexpected failures and associated accidents.

・Tracking Analysis of Vibration and Noise in Rotating Machinery
We analyze vibration and noise generated by rotating machinery such as motors, generators, and transmissions, breaking down the frequency components according to rotational speed. This allows us to identify at which rotational speeds specific vibrations or noises become prominent. We offer a comprehensive total solution, from sensor measurement to data analysis.

We visualize motor noise and vibration issues to support improved performance and quality.
Our solutions specialize in the vibration and noise analysis of motors, which are essential components in manufacturing equipment and plant facilities. We offer a full lineup of sensors—including microphones and accelerometers—as well as measurement and analysis instruments. By utilizing FFT analysis, we contribute to anomaly detection, identification of resonance phenomena, and preventive maintenance.
In addition to motors, we also provide detailed analysis of noise and vibration from a wide range of mechanical systems, including pumps, piping, automobiles, railway equipment, home appliances, and electronic components. Furthermore, we flexibly support on-site solutions requiring FFT analysis, such as resonance and frequency response evaluation of mechanical structures using electromagnetic shakers or impulse hammers.
