Abstract

The invention provides a motor rotating speed measuring device comprising a signal detector used for collecting a motor state signal; the controller is connected with the signal detector and is used for calculating the motor state according to the motor state signal acquired by the signal detector; the signal detector comprises a first signal detector arranged along the X axis, a second signal detector arranged along the Y axis and a third signal detector arranged along the Z axis. A plurality of signal detectors are arranged in the X-axis direction, the Y-axis direction and the Z-axis direction to point to different directions, measurement can be carried out in any direction, a magnetic field in any direction can be measured, the signal detector on the side detects a motor state signal, the waveform of the signal and the rotating phase of the motor are synchronous, the rotating speed of the motor can be calculated according to the frequency of the waveform, and the measurement accuracy is improved. The rotating speed of the motor can be effectively measured.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of motor detection, and in particular, to a device for measuring the rotational speed of a motor. Background technique [0002] In various motor applications and manufacturing occasions, it is necessary to measure the speed of the motor. The traditional methods include photoelectric method, stroboscopic light source reflection observation method and so on. The principle of the photoelectric method is to use a pair of luminescent tubes and photosensitive receiving tubes to count the received reflective signals against a certain reflective mark 43 provided on the turntable 42 above the rotating motor 41, and then the motor can be measured. Rotational speed, this method must have an optical mark linked to the rotating part of the motor, and the measuring device must illuminate the observation mark in a small range of directions (see figure 1 ). Another method that is slightly more compli...
