As an alternative of estimating the magnetic state by exterior alerts, COBROS™ straight measures the magnetic fields (B-fields) contained in the motor, each for the stator and the rotor fields.
Lisle, IL – September 23, 2025 – CTS Company, a worldwide chief in sensing and movement management applied sciences, at this time introduced the launch of COBROS™, a revolutionary new platform for electrical motor management. Developed over seven years of intensive analysis and improvement, COBROS™ introduces a basically new method to motor management through the use of real-time, in-situ magnetic subject sensing.
Historically, vector-controlled motors depend on oblique measurements to estimate the magnetic state contained in the motor. These strategies usually contain separate sensors for rotor place, akin to encoders or resolvers, and present sensors like shunt resistors or Corridor-effect units. Whereas efficient, these parts add price, complexity, and introduce limitations in accuracy and system integration.
COBROS™ affords a brand new answer.
As an alternative of estimating the magnetic state by exterior alerts, COBROS™ straight measures the magnetic fields (B-fields) contained in the motor, each for the stator and the rotor fields. A customized PCB sensor is embedded contained in the motor, comparable in type to a regular inductive place sensor, however can seize the total magnetic subject information in actual time. This eliminates the necessity for 3 discrete present sensors and a place sensor, permitting for simplified design, weight discount and extra exact management.
COBROS™ represents a step change in how we management electrical motors,” mentioned Javier Bilbao, Director of Product Administration at CTS Company. “By shifting from oblique estimation to direct measurement of the magnetic subject, we are able to considerably enhance accuracy and dynamic efficiency whereas additionally decreasing system complexity and price. This innovation permits a brand new stage of integration for our prospects in automotive, industrial, and robotic purposes.”
The COBROS™ sensor expertise relies on superior magnetic sensing components akin to Corridor and TMR (Tunnel Magnetoresistance). These mixed with a brand new sign processing structure, allow multidimensional decomposition of the motor’s magnetic subject. The compact, PCB-based design integrates simply into normal motor architectures, offering a seamless improve path for OEMs and system builders.
With COBROS™, CTS delivers a brand new normal in electrical motor management. Prospects profit from improved effectivity, diminished system price, and simplified integration; all by a wiser, extra exact method to motor sensing.
