ABB Files New Patent for Intelligent Motor Monitoring

Zurich, Switzerland — Global leader in industrial automation and electrification technologies, ABB Ltd., Switzerland, has filed a patent titled “Method for Monitoring a Motor” (Publication Number: CN121917962A) on October 2025.

The patent introduces an innovative method for monitoring motor condition. The method involves the following key steps:

1. Baseline Acquisition: Using a machine learning model, a baseline of monitored motor parameters is established based on a set of measured sensor values and motor parameters. The measured values come from sensors installed on the motor, while the motor parameters are obtained from the motor drive, including its configuration settings.

2. Real-Time Measurement: The monitored parameters are measured in real-time while the motor is controlled using the same drive configuration parameters as used for the baseline.

3. Comparison and Analysis: The real-time measurements are compared against the baseline.

4. Fault Detection: If any monitored parameter deviates from the baseline beyond a predefined threshold, a fault in the motor is determined.

By combining machine learning with real-time parameter monitoring, this method enables highly accurate and efficient motor fault detection. It provides reliable predictive maintenance support for industrial automation systems, helping to minimize unexpected downtime and reduce maintenance costs.
