Beschreibung
Zusammenfassung:	The utility model provides a magnetic encoder, which comprises a magnetic drum, magnetic signal detection elements and a magnetic signal processing output element, M monopole magnetic rings are arranged on the peripheral wall of the magnetic drum along the axial direction of the magnetic drum, n magnetic signal detection elements are arranged in the magnetic field range of each monopole magnetic ring along the circumferential direction of the monopole magnetic ring, protrusions and grooves are sequentially and alternately arranged on the outer circumferential faces of the single-pole magnetic rings in the circumferential direction of the single-pole magnetic rings, the central angle corresponding to the protrusions is alpha, the central angle corresponding to the grooves is beta, the deflection angle of the protrusions of every two axially adjacent single-pole magnetic rings in the circumferential direction of the magnetic drum is A, and the deflection angle of the protrusions of every two axially adjacent si
