Mechanical synchronous motor positioning structure

Abstract

The invention discloses a mechanical synchronous motor positioning structure. The structure comprises a motor body, wherein a front end of the motor body is connected with a main shaft, the front endof the motor body is covered with an outer cover, the main shaft penetrates through the outer cover and then is connected with a hand wheel, and a first sensing mechanism and a second sensing mechanism which are used for detecting the rotating speed of the main shaft are arranged in the outer cover; the first sensing mechanism and the second sensing mechanism are arranged on the main shaft of themotor main body, the first sensing mechanism and the second sensing mechanism are located on the two sides of the main shaft, the first sensing mechanism and the second sensing mechanism are connectedwith the controller, and the controller is installed on the motor main body; through arranging the first sensing mechanism and the second sensing mechanism on the main shaft of the motor main body ina linked mode, the first sensing mechanism and the second sensing mechanism are connected with the controller, the first sensing mechanism and the second sensing mechanism in different modes are usedfor measuring the speed of the main shaft of the motor body at the same time, results obtained by the two sets of sensing mechanisms are compared and displayed through the controller, and therefore the speed measuring structure is more accurate.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a mechanical synchronous motor positioning structure. Background technique [0002] A motor is an electrical device that converts electrical energy into mechanical energy and then uses the mechanical energy to generate kinetic energy to drive other devices. There are many types of motors, but they can be roughly divided into AC motors and DC motors for different occasions. [0003] The traditional driving motor needs to obtain the parameters of the rotational position, angle and steering as a reference for control. Generally, the encoder is directly installed on the motor shaft. Usually, only one set of encoders is used to sense each parameter, and one set of speed measurement is used. The structure makes it impossible to sense in time when there is an error in the speed measuring structure. Moreover, when a single group of speed measuring structure is damaged, it cannot continue...

Problems solved by technology

[0004] The purpose of the present invention is to provide a mechanical synchronous motor positioning structure to solve the above-mentioned background technology, which usually only uses a set of encoders to sense various parameters, and uses a set of speed measurement structures, so that when there is an error in the speed measurement structure, it cannot be sensed in time. Furthermore, when the single-group speed measurement structure is damaged, it cannot continue to measure, which is limited by the problem
