Abstract：The flatness measurement and control are the key technology to improve the flatness quality of the cold rolling strip. The structure and size of the flatness measurement rollers of different rolling mills are quite different，and the electric drive of the flatness meter may be active or passive. An unreasonable electric drive of the flatness meter may cause the slippage between strip and roller，which may scratch the strip. To solve the above problem，the overall selection criteria of active and passive schemes are elaborated firstly. Then，the concept of the skidding safety factor is put forward，and the main factors causing skidding are analyzed. The skidding safety factor is taken as the criterion for selecting the electric drive scheme of the new flatness meter. Aiming at the passive scheme，the specific measures for increasing skidding safety factor are put forward. Aiming at the active scheme，specific motor selection theory is established. Finally，different electric drive schemes are verified through two sets of industrial flatness measurement meter.
