![Sensorless Control during an open-phase fault](https://www.redrives.eu/en/wp-content/uploads/2015/11/sensorless_under_fault.jpg)
Most of high performance closed-loop controls require an additional sensor mechanically coupled to the rotor shaft for measuring the rotor position. Such a sensor reduces the reliability of the drive and increases its cost and complexity. We are able to control a drive in the full speed range, from standstill to rated speed and beyond […]
