Electrical machine e.g. linear synchronous motor has flux-guiding element arranged transversely to movement direction of rotor to form magnetically conducting bridge between stator and rotor

摘要

The electrical machine (100) has several rotor magnets (119) or and the rotor magnetic poles provided at pole face (120) of rotor (111). A sensor unit (125) with flux-guiding element (126,127) and the magnetic sensor element (128) is provided for detecting relative position between the stator (112) and rotor. The flux-guiding element is arranged transversely to the movement direction (117) of rotor to form a magnetically conducting bridge between the stator and the rotor.
