HLU Industrial Seminar: Semiconductor solutions for motor phase current sensing in industrial robots
Study, Events |
Date: 13 November, Thursday, 2025 17:00 – 19:15;
Speaker: Martin Staebler, System Engineer, Texas Instruments;
Location: TUM Main Campus Room 1100.
Participants: All students are welcome.
Introduction
Industrial drives are used in various applications to control the torque, speed, and position of electric motors, such as multi-axis robots, in factory automation. Join us for an introduction to industrial robotics drives and learn about the design challenges associated with motor phase current sensing, as well as how they are solved in industry. We close with a live motor control demo to compare four different current sense topologies based on shunt and in-package Hall sensors.
Agenda
- Introduction to industrial drive systems
- Motor current sensing in 3-phase inverters
- Where to measure and how to sense (shunt or magnetic)
- How to convert from analog to digital?
- How system requirements impact the current sense signal chain selection
- Discussion
Speaker
Martin Staebler graduated 1994 at the University of Stuttgart as Dipl.-Ing. in electrical engineering. In 1995 he joined Texas Instruments in Freising. Since 2014 he is a system engineer and senior member technical staff in the industrial systems motor drive team, where he specifies and develops reference designs for use in industrial drives.
