    • The present invention relates to a method of establishing a press fit of a component with a mounting hole on a shaft. It aims at providing a method that allows exact positioning of the component to be mounted on the shaft as well as a flexible way of use. To this end, the method is so conceived that an inner surface of the mounting hole of the component and/or a circumferential surface of the shaft is/are partially fused so that calotte-shaped projections protruding beyond the inner surface of the mounting hole and/or the circumferential surface of the shaft will form, that the component and/or the shaft is/are subsequently cooled, so that the calotte-shaped projections will solidify, and that the component is then slipped onto the shaft until the mounting hole is positioned in a fastening area of the shaft. In addition, the present invention also relates to components for establishing a press fit of a shaft-hub connection.
    • 本发明涉及一种在轴上建立具有安装孔的部件的压配合的方法。 其目的在于提供一种方法,其允许将要安装在轴上的部件精确定位以及灵活的使用方式。 为此,该方法是这样构想的:部件的安装孔的内表面和/或轴的圆周表面被部分地熔合,使得突出超过安装孔的内表面的凹凸形突起,以及 /或轴的圆周表面将形成组件和/或轴随后被冷却,使得卡尔托特形状的突起将固化,并且该部件然后滑动到轴上,直到安装孔为 定位在轴的紧固区域中。 此外,本发明还涉及用于建立轴 - 毂连接的压配合的部件。

    • 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。
