  • Encoder, motor and controlling method of encoder
    Patent number: 11342818
    Abstract: A controlling method of an encoder includes: detecting a rotation angle of a rotor of a motor coupled to the encoder to generate a first counting trigger signal and a second counting trigger signal so as to perform a turn number counting procedure; determining whether a period that an operating voltage of a driving circuit of the motor is smaller than a threshold voltage exceeds a preset time; and when the period exceeds the preset time, controlling a switching unit of the encoder to allow a battery of the encoder to provide a backup voltage to the encoder such that the encoder enters a low power processing procedure.
    Type: Grant
    Filed: November 23, 2020
    Date of Patent: May 24, 2022
    Assignee: DELTA ELECTRONICS, INC.
