Insights
CTS's new COBROS platform represents a significant innovation in motor control, eliminating components while improving performance and reducing costs.
CTS Corporation's COBROS platform introduces a fundamental shift in electric motor control technology by directly measuring magnetic fields inside motors rather than relying on traditional estimation methods. This breakthrough eliminates the need for separate position and current sensors, which reduces system complexity, weight, and cost while simultaneously improving control accuracy.
The technology's core innovation lies in its ability to capture real-time B-field data for both stator and rotor using embedded PCB sensors with Hall and TMR (Tunnel Magnetoresistance) elements. By moving from indirect estimation to direct measurement, COBROS addresses key limitations in conventional vector-controlled motors.
From a technical perspective, this approach offers significant advantages. Traditional systems require separate encoders or resolvers for position sensing and current sensors for field estimation – each adding complexity, cost, and potential points of failure. COBROS integrates these functions into a single sensing solution that provides more precise data directly from the magnetic source.
For CTS's customers in automotive, industrial, and robotics sectors, this technology enables simpler designs with better performance characteristics. The PCB-based implementation ensures compatibility with standard motor architectures, creating a straightforward upgrade path that minimizes adoption barriers for OEMs.
After seven years of R&D investment, this product represents a meaningful extension of CTS's core capabilities in sensing and motion control. By delivering improved efficiency with reduced system cost and complexity, COBROS addresses critical industry pain points while strengthening CTS's competitive position in the electric motor control market.
LISLE, Ill., Sept. 23, 2025 (GLOBE NEWSWIRE) -- CTS Corporation, a global leader in sensing and motion control technologies, today announced the launch of COBROS, a revolutionary new platform for electric motor control. Developed over seven years of intensive research and development, COBROS introduces a fundamentally new approach to motor control by using real-time, in-situ magnetic field sensing.
Traditionally, vector-controlled motors rely on indirect measurements to estimate the magnetic state inside the motor. These methods typically involve separate sensors for rotor position, such as encoders or resolvers, and current sensors like shunt resistors or Hall-effect devices. While effective, these components add cost, complexity, and introduce limitations in accuracy and system integration.
COBROS offers a new solution.
Instead of estimating the magnetic state through external signals, COBROS directly measures the magnetic fields (B-fields) inside the motor, both for the stator and the rotor fields. A custom PCB sensor is embedded inside the motor, similar in form to a standard inductive position sensor, but can capture the full magnetic field data in real time. This eliminates the need for three discrete current sensors and a position sensor, allowing for simplified design, weight reduction and more precise control.
“COBROS represents a step change in how we control electric motors,” said Javier Bilbao, Director of Product Management at CTS Corporation. “By moving from indirect estimation to direct measurement of the magnetic field, we can significantly improve accuracy and dynamic performance while also reducing system complexity and cost. This innovation enables a new level of integration for our customers in automotive, industrial, and robotic applications.”
The COBROS sensor technology is based on advanced magnetic sensing elements such as Hall and TMR (Tunnel Magnetoresistance). These combined with a new signal processing architecture, enable multidimensional decomposition of the motor’s magnetic field. The compact, PCB-based design integrates easily into standard motor architectures, providing a seamless upgrade path for OEMs and system developers.
With COBROS, CTS delivers a new standard in electric motor control. Customers benefit from improved efficiency, reduced system cost, and simplified integration; all through a smarter, more precise approach to motor sensing.
