Embodiment Construction

[0010] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0011] Such as figure 1 and figure 2 As shown, a fixed structure for motor speed signal output, including a pulse wheel 2 on the motor shaft 1, a finger sensor 3 coupled with the pulse wheel 2, and a fixed finger sensor 3 on the motor shaft 1 Radial device, the above-mentioned finger sensor 3 is: the front end of the finger sensor 3 is a slender cylinder, and the rear end is connected with an output cable and a mounting screw hole. The finger sensor 3 is L-shaped as a whole, for example: SNDH produced by HONEYWELL The -T4L-G01 sensor belongs to this structure. The finger sensor 3 can be coupled with the toothed pulse wheel 2 to output the speed signal to the controller, thereby realizing the speed control of the motor. The radial device includes an end cover 4 fixedly arranged on the motor shaft 1 below the pulse wheel 2, a baffle plate 5 integrally formed...

Abstract

The invention discloses a part in the field of motors, in particular to a fixed structure of motor speed signal output for feeding back and controlling the motor speed. The fixed structure is characterized by comprising a pulse wheel on a motor shaft, a finger-shaped sensor coupled with the pulse wheel and further comprising a radial device for fixing the finger-shaped sensor and arranged on the motor shaft. The radial device comprises an end cover which is arranged on the motor shaft and fixedly arranged below the pulse wheel, a retaining board which is arranged outside the pulse wheel and integrally molded and a hole corresponding to the finger-shaped sensor in size and shape at the radial position of the end cover. A certain distance is left between the finger-shaped sensor and the pulse wheel, and a semi-closed cavity is formed by the end cover and the retaining board arranged above the end cover. The fixed structure of motor speed signal output is free of abrasion, convenient to install and convenient to daily maintain, and saves cost.

Description

technical field [0001] The invention relates to a component in the field of motors, in particular to a fixed structure for outputting motor speed signals for feedback and control of the motor speed. Background technique [0002] At present, in the field of motors, the equipment used to control the speed of rotation of the motor mainly uses sensor bearings. However, sensor bearings are moving parts and are easily damaged. Once damaged, it is very inconvenient to disassemble, replace and repair the whole machine. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a fixed structure for motor speed signal output without wear, convenient for installation and daily maintenance, and cost-saving. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a fixed structure for motor speed signal output, which is characterized in that it includes a pulse wheel on t...
