摘要： An electric motor has a stator and a rotor (14) which can rotate about a rotation axis (85). This has a sensor magnet (82) with an even number of sensor poles (71, 72, 73, 74). The sensor magnet (82) is designed to produce a magnetic flux with a magnetic flux density which has a sinusoidal profile over the rotation angle. Furthermore, at least two analogue rotor position sensors (460, 465) are provided in order to produce analogue rotor position signals (B_S1, B_S2) which characterize the magnetic flux density of the magnetic flux acting on the respective sensor (460, 465) from the sensor magnet (82). These analogue rotor position sensors (460, 465) are arranged in the area of the circumference of the sensor magnet (82) on a common planar mount arrangement (468), which is essentially parallel to the rotation axis (85) of the sensor magnet, where the mount arrangement (468) is intersected by a first plane (470) that is at right angles to the rotation axis (85). These analogue rotor position sensors (460, 465) are arranged at such a distance from one another on the mount arrangement (468) that they produce two sinusoidal signals (B_S1, B_S2) with a phase shift of 90° during operation. A signal generator (90) is used to produce at least one pulsed signal (A, B) from these two sinusoidal signals (B_S1, B_S2) which have been phase-shifted through 90°. The instantaneous rotation speed can be determined accurately from this pulsed signal.

摘要翻译： 电动机具有可绕旋转轴线（85）旋转的定子和转子（14）。 这具有传感器磁体（82），其具有偶数个传感器极（71,72,73,74）。 传感器磁体（82）被设计成产生具有在旋转角度上具有正弦曲线轮廓的磁通量密度的磁通量。 此外，提供至少两个模拟转子位置传感器（460,465）以产生表征作用于相应传感器（460）上的磁通量的磁通量密度的模拟转子位置信号（B'，S1，B'，S2） ，465）与传感器磁体（82）分离。 这些模拟转子位置传感器（460,465）在传感器磁体（82）的圆周区域中布置在共同的平面安装布置（468）上，所述平面安装布置基本平行于传感器磁体（82）的旋转轴线 ，其中安装装置（468）被与旋转轴线（85）成直角的第一平面（470）相交。 这些模拟转子位置传感器（460,465）在安装装置（468）上彼此间隔这样的距离布置，使得它们在操作期间产生具有90°相移的两个正弦信号（B'，B'，B'，B'） 。 信号发生器（90）用于从已经相移90°的这两个正弦信号（B'，S1，B'，S2）产生至少一个脉冲信号（A，B）。 瞬时转速可以从该脉冲信号准确地确定。
