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.

Abstract: A motor brake device includes an armature base, an armature plate, a fixing plate and at least one brake lining. The armature plate is disposed on the armature base. The armature plate is vertically movable relative to the armature base. The fixing plate is fixed on the armature base. The fixing plate and the armature base are located at two opposite sides of the armature plate. The braking assembly is arranged between the armature plate and the fixing plate, and includes a two-winged rotor hub plate, a brake friction plate and at least two elastic elements. The at least one brake lining is arranged between the armature plate and the braking assembly and/or between the fixing plate and the braking assembly.
