ROTARY MACHINE WITH POSITION SENSOR

The invention relates to a rotary machine (1), in particular an electric motor (1), having a position detection means (4) for detecting a rotational position of a pole rotor (2) that can be rotated about an axis of rotation, wherein the pole rotor has a periphery (22) and wherein the position detection means (4) has at least one first position sensor (42) for detecting a change in the magnetic field (H) and at least one magnetic element (44) is arranged on the pole rotor, and wherein the position detection means further has at least one printed circuit board (6), electronic components are arranged on the printed circuit board, and the first position sensor (42) is also arranged at least indirectly on the printed circuit board. According to the invention, the first position sensor (42) extends at least partially into the space of the pole rotor surrounded by the periphery (22). 本发明涉及一种旋转机器（1）、尤其是电动马达（1），具有用于对能够围绕着旋转轴线旋转的磁极转子（2）的旋转位置进行检测的位置检测机构（4），其中这个磁极转子具有周缘（22）并且其中这个位置检测机构（4）具有至少一个用于对磁场（H）的变化进行检测的第一位置传感器（42）
