| Abstract |
This work presents a new torque calculator for winders with AC motor. A precise torque with a defect lower than 1 % is often required for an axial winder in the paper or iron- and steel industry. These demands are hard to please and at the moment realised only with DC- drives. The reasons to use AC motors in winders are their higher qualities with respect to robustness and maintainance. The implementalion of an exactly torque computation for an AC motor is more difficult than for a DC motor because there exist more variablt machine parameters (inductances and resistances). This paper shows a torque calculator with a robust flux observer, which permits to compute the torque with a precise statical and good dynamical behavoir. |
