Abstract

The invention provides an encoder, a motor and automation equipment. The encoder comprises a circuit board and a magnetic part capable of moving relative to the circuit board. The circuit board comprises: at least three magnetic induction modules used for inducing changes of magnetic signals of the magnetic part to generate two kinds of magnetic coding signals, and according to the two kinds of magnetic coding signals, obtaining the running direction, the turn value and the absolute position of the encoder at the current moment; at least one light sensing module used for sensing the change of the light signal of the encoder to generate a light encoding signal so as to obtain the relative position of the encoder at the current moment; and a signal processing unit connected with each module so as to determine the position information of the encoder at the current moment according to the running direction, the turn value, the absolute position and the relative position of the encoder at the current moment. The problem that a photoelectric encoder or a magnetoelectric encoder in the prior art cannot meet the requirements of high precision and interference resistance at the same time is solved.

Description

technical field [0001] The invention relates to the technical field of encoders, in particular to an encoder, a motor and automation equipment. Background technique [0002] The photoelectric encoder includes a photoelectric code disc. The center of the photoelectric code disc is sleeved on the rotating shaft. The photoelectric code disc is provided with annular light and dark engraved lines. The photoelectric encoder also includes a light emitting device and a light receiving device to pass through the light. The receiving device reads the optical signal sent by the light emitting device and converts it into an electrical signal, which is mainly used to measure displacement or angle. It has a simple structure and high precision, but its anti-interference ability is weak. In addition, since the photoelectric encoder calculates the accuracy through the engraved lines on the code disc, the higher the accuracy, the larger the code disc and the larger the total volume of the enc...
