Axially multi-pole magnetized magnet, device with magnetically multipole magnetized magnet, use of the device for detecting the rotation angle and use of the device for electrical commutation in electric motors
Axial multi-pole magnetized magnet (10, 40, 100) having at least in a radial region a thickness D (φ) varying over the angle of rotation (φ), the thickness D (φ) resulting from the addition of a constant D and the magnitude a sum of cosine functions having a fundamental and its odd harmonics, comprising at least terms up to the fifth harmonic, where N is a predetermined positive integer, DNull or a positive, the quotient D / your is negative, and the quotient D / is your positive value, ABS ( D) ≥ABS (D) ≥ABS (D) and where ABS [] and ABS () respectively denote the respective amount of the number enclosed by the bracket.
