Abstract

The invention belongs to the technical field of motor accessories, and particularly relates to a servo motor encoder and a signal generating method. The technical problem that the precision is poor in the prior art is solved. The servo motor encoder comprises a shell. A photoelectric encoder and a rotating coded disc working in cooperation with the photoelectric encoder are arranged inside the shell. When the rotating coded disc rotates, a first set of signals can be generated by the photoelectric encoder, and a magnetic sensor chip and a rotating magnet working in cooperation with the magnetic sensor chip are arranged inside the shell; when the rotating magnet rotates, a second set of signals can be generated by the magnetic sensor chip. The signal generating method comprises the following steps of A signal generation and B differential signaling. The servo motor encoder and the signal generating method have the advantages that the design is more reasonable, precision is high, the cost is low, and practicability is high; the structure is simple, and manufacturing is easy; the signal stability is good, the service life is long, and the servo motor running stability is further improved; the method is simple, easy to control and low in running cost.

Description

technical field [0001] The invention belongs to the technical field of motor accessories, and in particular relates to a servo motor encoder and a signal generating method. Background technique [0002] An encoder is a device that compiles and converts a signal (such as a bit stream) or data into a signal form that can be used for communication, transmission, and storage. Encoders applied to servo motors usually use a combination of a photoelectric encoder and a rotary code disc to collect signals, or a combination of a rotating magnet and a magnetic sensor chip to collect signals. However, when the servo motor is used in occasions with high control precision and poor working environment, there are servo motor encoders composed of photoelectric encoders and rotary code discs, and servo motor encoders composed of rotating magnets and magnetic sensor chips. Certain deficiencies. Although the servo motor encoder composed of a photoelectric encoder and a rotary code wheel can ...
