Sensorless Vector Control Drives

Sensorless vector control, also known as field-oriented control, outputs performance comparable to that of a motor drive using position/velocity feedback — in turn decreasing drive-system cost.

Some applications require a compact design; others in corrosive, extremely hot, or otherwise hostile environments necessitate that designs be free of additional wiring (for sensors or devices mounted on the shafts and so on.) Sensorless vector control benefits designs in both of these situations.
