Position sensor e.g. for servo drive, has printed circuit board and swiveling magnetic field, its angle position assigned to position to motor shaft of electrical driving motor

摘要

The position sensor has a printed circuit board (10) and a swiveling magnetic field (12), its angle position assigned to the position to a motor shaft (14) of an electrical driving motor. On the printed circuit board two resounding sensors (16, 18) are located. A magnetic flow guide (24, 26) extends to the magnetic field. The magnetic field is a ring, which has a permanent magnet.
