Nissei Success Story

ADI OtoSense Smart Motor Sensor (SMS) Enables Predictive Maintenance Insights at Nissei Facility

Nissei uses Analog Devices smart motor for predictive maintenance of the homogenizers at the Lake Biwa Plant. The smart motor sensor collects data on motor vibration, temperatire and magnetic flux and uses AI to analyze the data. This analysis provides a clear view of the state of the motor, performing optimized diangostics for each individual units.

The Challenges

In the face of unexpected breakdowns, Nissei Co. was thrust into a critical test, safe-guarding the soul of Japan’s adored soft serve ice cream. The stakes were high: the emulsification process’s success hinges on precise temperature control—a homogenizer failure meant not just a pause, but a complete operational freeze, necessitating discards of in-process product.

The Solution

The adoption of ADI OtoSense Smart Motor Sensor was transformational, turning reactive measures into a proactive strategy that significantly boosted reliability and throughput of the production line. The SMS' AI-driven vigilance over temperature, vibration, and magnetic flux preemptively spots and addresses potential faults, preventing interruptions or quality lapses. By comparing real-time data to a ‘digital normal,’ the system proactively signals deviations, prompting immediate corrective action. This predictive approach reduces wastage, ensures uninterrupted production, and preserves product excellence—factors that are instrumental in fortifying Nissei’s market position and operational superiority

Implementation

ADI OtoSense SMS helps continuously monitor homogenizers at Nissei’s Lake Biwa factory, so Nissei can take a proactive approach to maintenance and ensure efficient, high-quality production of its product. While traditional indicators like temperature and vibration anomalies can serve as precursors to imminent failure, the Smart Motor Sensor takes early intervention to the next level by comparing real-world data to an AI model of the system in its optimal operational state. This advanced approach ensures that problems are addressed well before they escalate, effectively averting operational disruptions. This approach also liberates technicians from the monotonous task of continuous monitoring. As a result, they can redirect their expertise towards resolving identified issues promptly and effectively, contributing significantly to overall operational excellence.

Overall, implementing the Smart Motor Sensor significantly boosted critical machinery uptime and continuous motor monitoring for peak performance, resulting in a substantial reduction in downtime.
