  • Purpose – The purpose of this paper is to derive a force‐velocity characteristic for an eddy current brake with minor computational effort.

    Design/methodology/approach – The speed range is split into two domains. While in the low‐speed domain it is possible to achieve a closed form expression for the force‐velocity characteristic in the high‐speed region approximations have to be introduced.

    Findings – The derived relation for the force‐velocity characteristic has been compared with measurement results. The comparison shows that the approach yields good results for not too large air gaps.

    Originality/value – A combination of analytical and approximative methods has been used for the determination of the force‐velocity characteristic of an eddy current brake with two pole pairs.
