Briefly

The real-time VFD monitoring system detects issues with Variable Frequency Drives (VFDs) in Amazon fulfillment centers, potentially preventing thousands in equipment damages and operational disruptions. It monitors over 500 VFDs every two seconds, processes data for effective alerts, and minimizes false positives. Alerts are sent to the PDM team, allowing quick interventions. The system is designed to ensure efficient maintenance with long-term data storage in AWS S3, all while costing approximately $0.06 per month operationally. This innovative solution significantly enhances VFD health visibility and reduces unnecessary downtime.
The real-time VFD monitoring system monitors over 500 VFDs every two seconds, enabling timely responses to potential failures and significantly reducing downtime and maintenance costs.
By filtering out false positives and providing focused alerts, the system ensures that technician responses are both efficient and effective, ultimately saving valuable time and resources.
Operating at a cost of approximately $0.06 per month, the monitoring system demonstrates how advanced technology can be implemented cost-effectively to prevent failures and maintain operational efficiency.
The monitoring app sends alerts directly to the PDM team, allowing for prompt action on overload situations and reducing the risk of significant equipment damage.
