US 2025/0085142 A1 · AUTOMATIC CALIBRATION OF ENCODERS BASED ON TEMPERATURE

Abstract

Novel tools and techniques are provided for implementing an encoder capable of performing a self-calibration or self-correction process, and more particularly methods, systems, and apparatuses are provided for implementing an encoder capable of performing a process to calibrate itself or correct a signal of a sensor at different detected temperatures of an environment. In various embodiments, the encoder includes an exciter and a sensor capable of detecting a position of the exciter and generating a signal based on the position of the exciter. The encoder can then perform one or more steps to calibrate itself or self-correct a signal at different temperatures and calculate one or more values to correct a signal generated by the sensor.

Dependent claims

An encoder comprising:

an exciter;
a first sensor configured to detect a first temperature of an environment;
a second sensor configured to detect a position associated with the exciter and generate a signal based on the position associated with the exciter;
and
a controller configured to:
detect the first temperature of the environment using the first sensor;
determine a first process to correct the signal has not been run for the first temperature;
based on a determination that the first process has not been run for the first temperature, running the first process to correct the signal based on the first temperature;
and
based on the first process and the first temperature, calculate a first value to correct the signal received from the second sensor.
