NON-VOLATILE SHAFT ANGLE SENSOR Russian patent published in 2023 - IPC G01P3/44 

FIELD: instrumentation.

SUBSTANCE: non-volatile shaft angular position sensor contains a rotor, which includes a magnetic circuit, internal and external inductor coupling halves, made in the form of multi-pole magnetic rings; a stator including a magnetic core and field windings located on radially mounted stator cores; the rotor is located coaxially inside the stator; the rotor and stator are made in the form of a generator with excitation from permanent magnets, which includes a rotor magnetic circuit, permanent magnets of the internal and external inductor coupling halves, a stator magnetic circuit and field windings; printed circuit board with electronic circuit; magnetically sensitive elements made with the ability to measure the parameters of the magnetic field of permanent magnets rotating together with the controlled shaft.

EFFECT: increased efficiency and expanded capabilities of the sensor.
