Abstract

The invention provides a motor and a rotating speed measuring device thereof. The rotating speed measuring device of the motor comprises a coupling arranged on an output shaft of the motor, a Hall element and a control unit, wherein the front surface of the coupling is provided with a first hole site, and the first hole site is provided with a magnet; the Hall element is used for detecting the magnet and outputting a corresponding level signal; and the control unit is connected with the Hall element and used for measuring the rotating speed of the motor according to the level signal. According to the motor rotating speed measuring device, the measuring accuracy is high, manual frequency modulation and marking are not needed, and a lot of manpower resources are saved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor speed measuring device and a motor. Background technique [0002] In related technologies, the method of measuring the motor speed is to use a stroboscope to measure the speed of the motor, which not only requires manual frequency adjustment, but also requires manual marking on the motor, which is easily affected by external factors, such as light and other factors. Therefore, the measured The accuracy is low, and it needs to consume a lot of human resources. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a motor speed measuring device, which not only has high measurement accuracy, but also does not need manual frequency modulation and marking, which saves a lot of human resources. [0004] The technical scheme that the present invention adopts is as follows: [0005] A motor speed measuring device, com...
