Angular displacement measuring arrangement, angular displacement measuring system and electric motor
Abstract:
A rotary angle measuring arrangement includes a shaft, and a rotary angle measuring system which detects a rotary shaft movement. The rotary angle measuring system includes an excitation unit connected to the shaft which generates a magnetic field, a magnetic field sensor, a PCB arrangement, and an evaluation electronics arranged on the PCB arrangement and electrically connected to the magnetic field sensor. The PCB arrangement includes a first PCB section arranged perpendicular to a longitudinal axis of the shaft, and a second PCB section angled with respect to the first PCB section and electrically connected thereto. The magnetic field sensor is arranged on the first PCB section. The magnetic field is detectable via the magnetic field sensor. A parallel projection of the second PCB section onto a longitudinal plane parallel to the longitudinal axis and a parallel projection of the excitation unit onto the longitudinal plane at least partially overlap.
