    • The invention relates to a method carried out with simple means for determining the position of the rotor in a sensorless and brushless multi-phase electric motor (1) in addition to a device particularly suitable for carrying out said method. According to said method, a phase voltage (Uv) on the clamping side on said motor phase is to be detected after clamping a first motor phase (V) from the reference potentials (UZ,M) of an intermediate circuit (7) during a detection period (TE), via which the detection period (TE) determines a peak value (Uv*) of the detected phase voltage (Uv), the peak values (Uv*) are to be compared to the comparative value (Uc), and a positon signal (SP) is to be produced when the peak value (Uv*) exceeds the comparative value (U0). The comparative value (Uc) is then determined digitally such that it corresponds to the value of the phase voltage (Uv) at a zero crossing of a voltage (UVind) induced in the first motor phase (V) or an increased or lowered value in relation to a predefined correction value (DeltaQ).
    • 本发明涉及一种除了特别适用于执行所述方法的装置之外,用简单的装置确定转子在无传感器和无刷多相电动机(1)中的位置的方法。 根据所述方法,在一个中间电路(7)的基准电位(UZ,M)中钳位第一电动机相位(V)之后,将检测在所述电动机相位上的夹紧侧上的相电压(Uv) 检测周期(TE),通过其检测周期(TE)确定检测相电压(Uv)的峰值(Uv *),将峰值(Uv *)与比较值(Uc)进行比较, 当峰值(Uv *)超过比较值(U0)时,将产生位置信号(SP)。 然后,数字地确定比较值(Uc),使得其对应于在第一电动机相(V)中感应的电压(UVind)的过零点处的相电压(Uv)的值或增加或减小的值 与预定义的校正值(DeltaQ)的关系。
