Problems solved by technology

[0002] At present, most smart motors in the society do not have a tachometer function. Even if there is a tachometer function, most of them are calculated according to the current power input frequency, not the real value of the motor speed.

Embodiment Construction

[0008] attached below figure 1 A smart motor with a tachometer of the present invention will be described in detail below.

[0009] as attached figure 1 As shown, an intelligent motor with a tachometer of the present invention is composed of a motor rotor (1), a grid plate (2), a photoelectric switch (3), a display screen (4) and a single-chip microcomputer 5), and the grid plate (2) It is connected with the motor rotor (1) and the photoelectric switch (3), and the single-chip microcomputer (5) is connected with the photoelectric switch (3) and the display screen (4).

[0010] An intelligent motor with a tachometer uses the grating cutting pulse principle to calculate the speed. The grid plate is synchronized with the motor rotor. When the motor rotates, the grid plate cuts the photoelectric switch to generate a pulse signal. The single-chip computer calculates the motor speed according to the pulse frequency. Display the motor speed, and can provide the speed value to the u...

Abstract

The invention provides a smart motor with a tachometer. The smart motor consists of a motor rotor, a grating plate, a photoelectric switch, a display screen and a single-chip microcomputer, and is characterized in that the grating plate is connected with the motor rotor and the photoelectric switch; and the single-chip microcomputer is connected with the photoelectric switch and the display screen. The smart motor has the beneficial effects that the rotating speed is calculated by the tachometer according to the principle of pulse cutting through a grating; the grating plate is synchronous with the motor rotor; when the motor rotates, the grating plate cuts the photoelectric switch to generate a pulse signal, and the single-chip microcomputer calculates the rotating speed of the motor according to pulse frequency; and when the motor works, the rotating speed of the motor can be displayed in real time, and a rotating speed value can be read by an upper computer or a lower computer to be applied to data analysis of a motor driven object.

Description

technical field [0001] The invention relates to a motor, in particular to an intelligent motor with a tachometer. Background technique [0002] At present, most smart motors in the society are not designed with a tachometer function. Even if there is a tachometer function, most of them are calculated based on the current power input frequency, not the real value of the motor speed. Contents of the invention [0003] In view of the deficiencies in the prior art above, the present invention provides an intelligent motor with a tachometer. The tachometer uses the principle of raster cutting pulses to calculate the speed. The grid is synchronized with the motor rotor. When the motor rotates, the grid cuts the photoelectric switch to generate Pulse signal, the single-chip microcomputer calculates the motor speed according to the pulse frequency, and the motor speed can be displayed in real time when the motor is working, and the speed value can be provided to the upper computer...
