<p>The machine (1) has a sensor device (5) for detecting a relative position between a stator (2) and a rotor (3). The sensor device has a magnetic sensor element e.g. Hall sensor (7), and a flux guiding element (6), which guides magnetic flux of rotor and/or main magnets (4) to the sensor element. The guiding element has pole sections (6a, 6b) for forming a back iron and a bar (6c) that connects the pole sections. The sensor element is positioned adjacent to the bar, and is arranged at a distance to the rotor. Air gap between the sensor element and the rotor is bridged by the guiding element.</p> |
