    • In a method for measuring the speed of an electrical machine having a stator, a rotor and a winding, in particular of an electronically commutated motor, a speed-measurement signal ω is sampled, in that a measured speed value ω(k) for the rotor is determined for each of a series of sampling instants. Moreover, a moment of inertia value for the mass moment of inertia of the rotor is determined. In addition, a current signal I is sampled, in that a current value I(k) for the electrical current in the winding is determined for each of the sampling instants. An estimated value ωs(k) for each of the measured speed values ω(k) is determined from a measured speed value ωk(k−1) assigned to an earlier sampling instant, from the current signal I and from the moment of inertia value. A tolerance band containing the estimated value ωs(k) is assigned to this estimated value ωs(k). If the measured speed value ω(k) lies outside of the tolerance band, the measured speed value ω(k) is replaced by a speed value ωk(k) that is within the tolerance band.
    • 在用于测量具有定子,转子和绕组(特别是电子换向电动机)的电机的速度的方法中,对速度测量信号ω进行采样,其中测量的速度值ω(k)用于 为一系列采样时刻中的每一个确定转子。 此外,确定转子的质量惯性矩的惯性矩值。 此外,对每个采样时刻确定绕组中的电流的电流值I(k),对电流信号I进行采样。 根据分配给一个测量速度值ω(k)的测量速度值ωk(k-1)来确定每个测量速度值ω(k)的估计值ωmax(k) 早期采样瞬间,从当前信号I和惯性矩值。 包含估计值ωga(k)的公差带被分配给该估计值ωga(k)。 如果测量的速度值ω(k)位于公差带之外,则测量的速度值ω(k)被公差带内的速度值ωk(k)代替。
