First-ever sensorless motor commutation
technology for applications seeing high
torques at low/zero speeds
First-ever sensorless motor commutation technology for applications seeing high torques at low/zero speeds

Proven, Fundamental Technology
In use in over 1 million vehicles for a traction application. Deployment since Mar 2018
Legacy Sensorless Motor Control
- Back-emf based. In use for decades.
- Useful for applications seeing low torques at low speeds e.g., fans, blowers, compressors.
- Not suited for applications requiring high torque at low/zero speeds e.g., vehicular traction, power tools, power steering.
SEDEMAC Sensorless Motor Control
- Leverages physics different from that of back-emf at low/zero speeds.
- Enables all speed sensorless commutation.
- Suitable for all electric machine driven applications including those requiring high torques at low/zero speeds.
