Abstract

A magnetic ring and sensor arrangement is provided. The magnetic ring and sensor arrangement includes a magnetic ring and a sensor sub-system. The magnetic ring includes an improved harmonic content.The sensor sub-system includes sensors coupled to the magnetic ring. Each of the sensors measures an amplitude or a direction of a magnetic field of the magnetic ring.

Description

technical field [0001] The invention relates to a high performance magnetic ring and sensor arrangement. Background technique [0002] For motor control using absolute position sensors (for example, delivering analog sine and cosines representing the angular position of the rotor), typically for geared motor generators, the accuracy requirements for the sensor output signal are increasingly important. Furthermore, mechanical torque needs to be properly controlled with the least amount of noise. The main source of inaccuracy in the sensor output is the magnetic ring itself. Because the transmitted magnetic field signal is not a perfect ( / perfect) sine wave, the magnetic ring does not provide a perfect picture of the angular position of the rotor. Contents of the invention [0003] According to one or more embodiments, a magnetic ring and a sensor arrangement are provided. The magnetic ring and sensor arrangement includes a magnetic ring and sensor subsystem. The magneti...
