Requirements for positioning accuracy and speed ripple are quite high in modern servo drives. To overcome these challenges, the whole feedback path should be carefully designed and the right sensors selected. Position sensors should be able to provide, at the same time, accurate and frequent information updates. Traditional incremental encoders or resolvers are inadequate in […]

Sensorless Control
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 […]
