Miniature servo for detecting angle by utilizing magnetic sensor and detection method of miniature servo

Abstract

The invention belongs to the technical field of servo detection and relates to a miniature servo for detecting an angle by utilizing a magnetic sensor. The miniature servo comprises a shell, a front cover and a rear cover; the shell, the front cover and the rear cover are fixedly connected with one another through a plurality of screws; a plurality of first screws are uniformly arranged on one side of the outer surface of the rear cover; a rotating shaft is fixedly mounted at one end of each worm and gear transmission mechanism; permanent magnets are fixed onto the end surfaces of the rotatingshafts through AB glue; a plurality of pressing blocks are fixedly installed on one side of the outer surface of the front cover; a main control PCB is fixedly installed on one side of the front cover through a plurality of third screws; a plurality of pressing plates and second grub screws are evenly and fixedly connected between the main control PCB and the front cover; and the pressing platesare fixedly connected to the main control PCB through a plurality of second grub screws. With the miniature servo for detecting the angle by utilizing the magnetic sensor adopted, the rotating angle of an output shaft can be detected more accurately and reliably; an angle control capacity is improved with the integration of the servo not affected; and the steering performance of a flying body is improved.

Description

technical field [0001] The invention relates to the technical field of steering gear detection, in particular to a miniature steering gear using a magnetic sensor to detect an angle and a detection method thereof. Background technique [0002] The traditional steering gear uses a carbon film potentiometer to detect the rotation angle of the output shaft, and the control board controls and maintains the angle of the output shaft according to the signal of the positioner. The traditional carbon film potentiometer has nonlinearity, weak moisture resistance, large current noise, and low resistance value. The shortcomings of relatively poor stability and poor anti-interference ability of the output analog signal make it difficult to meet the precise control requirements in special environments. [0003] With the promotion of application fields, the requirements for sensors are getting higher and higher. The invention adopts the magnetic sensor to detect the rotation angle of the...
