Abstract
Disclosed is a magnetic encoder, a method and system for detecting an absolute electrical angle, and a readable storage medium. The magnetic encoder includes a magnetoresistance sensor, a magnetic field auxiliary coil and a coil current control circuit electrically connected with the magnetic field auxiliary coil, the magnetoresistance sensor being a planar component, the coil current control circuit being configured to supply current to the magnetic field auxiliary coil, to allow the magnetic field auxiliary coil to generate an auxiliary magnetic field, the auxiliary magnetic field influencing the magnetic field component in the first direction and the magnetic field component in the second direction, forming a resultant magnetic field, and the magnetoresistance sensor being configured to detect the resultant magnetic field and the component of the 2-dimension magnetic field generated by the magnet.
