Prototype for smart electric drives in industry

An important milestone in the PowerCare project: At the third advisory board meeting at the Fraunhofer Institute for Microelectronic Circuits and Systems, the prototype for intelligent electric drives in industry was presented for the first time. The innovative system is intended to enable real-time health monitoring of electric motors, thereby helping to prevent failures and increase energy efficiency.

"After 1.5 years of highly innovative, but also high-risk development work, we can make the leap into industry with this prototype and further optimize electrification and automation, avoid failures and save electricity,” explains Alexander Stanitzki, Head of the Industry business unit at Fraunhofer IMS.

AI-supported real-time analysis for maximum reliability

The PowerCare prototype combines state-of-the-art gallium nitride (GaN) power semiconductors with embedded AI to monitor motor controls in real time. This intelligent technology boosts the efficiency of electric motors and increases their reliability. An innovative PWM (Pulse Width Modulation) controller with embedded AI continuously analyzes the status of the electronics and motor mechanics. This allows potential failures to be detected at an early stage and prevented through timely maintenance.

Challenge: real data for practical AI training

One of the biggest challenges in the project is adapting the AI models to real operating conditions. As the operating data for industrial drives can be read directly from the power electronics, no additional sensor technology is required. This operating data, for example on bearing damage and the wear of GaN semiconductors, makes it possible to further train and optimize the algorithms. This so-called “mission profile” ensures that the AI also works precisely under real conditions.

 Outlook: Two platforms for industrial tests by 2026

Two test platforms will be set up by April 2026 to test the results under realistic conditions:

  1. Demo case: a portable plug-and-play test environment for industrial customers. Here, companies can test the reliability of their specific applications - such as conveyor belts, pumps or drone motors - using PowerCare technology.
  2. Industrial motor test bench at Fraunhofer IISB: Here, the efficiency and integration of the innovative vertical gallium nitride semiconductors (vGaN) in a drive converter are tested under realistic industrial conditions.

The PowerCare project shows how intelligent technologies can drive electrification in industry and save resources at the same time. The successful prototype lays an important foundation for further transfer into practice.

The PowerCare project is funded as part of the Fraunhofer-Gesellschaft's internal programs, grant number PREPARE 40-06175.
