Problems solved by technology

The existing problem is that the visual observation of the rotating blades and direction indicators requires a certain length of observation, which is likely to cause visual fatigue. At the same time, in the static state, the indication effect of the direction indicators is obvious, but in the rotating state In this case, the inspector may have visual misjudgment
The problems pointed out above make it difficult to guarantee the detection effect and efficiency of manual visual observation and judgment

Abstract

The application relates to a motor rotation detection device, which belongs to the technical field of motor detection. The device comprises a rotation mechanism and two or more than two photoelectricdetection elements. The rotation mechanism having a central shaft hole is cooperatively installed with a motor shaft, and has an arc-shaped protruding portion in the axial plane direction. The two ormore than two photoelectric detection elements are configured as follows: the photoelectric detection elements are distributed around the rotation mechanism; when the motor drives the rotation mechanism to rotate, the arc-shaped protruding part can pass through the space between a transmitting part and a receiving part of each photoelectric detection element so as to be sequentially detected by the photoelectric detection elements, and binary codes formed by signals output by the photoelectric detection elements at the same time change periodically. According to the invention, a manual visualobservation and judgment mode is replaced, and the effect and efficiency of motor rotation detection can be ensured.

Description

technical field [0001] The application belongs to the technical field of motor detection, and in particular relates to a motor rotation detection device. Background technique [0002] In related technologies for motor rotation detection, for example, the motor is judged by installing fan blades and direction indicators (eg, arrow indicators), etc., supplemented by manual visual observation of rotating fan blades and direction indicators. The existing problem is that the visual observation of the rotating blades and direction indicators requires a certain length of observation, which is likely to cause visual fatigue. At the same time, in the static state, the indication effect of the direction indicators is obvious, but in the rotating state Under the circumstances, it may cause visual misjudgment by the inspectors. The problems pointed out above make it difficult to guarantee the detection effect and efficiency of manual visual observation and judgment. Contents of the i...
