Oscillation period is about 40-50uS (frequency is about 20-25KHz), that is to say, a square wave pulse is output every 45 microseconds or so. Due to component accuracy errors, the frequency can only be within a certain range;
|
|
|
5
|
Duty cycle (that is, the proportion of the entire cycle when the output is high) is about 5% -95%;
|
|
|
6
|
The output voltage amplitude is affected by the “555” chip voltage drop, which is slightly lower than the input voltage by about 2V;
|
|
|
7
|
The output terminal “-” and the input terminal “-” are grounded together.

This module can be matched with our shop’s AQMH3615NS to realize the speed regulation of the potentiometer. The wiring is shown in the figure below.
Among them, F1 and F2 are fuses, it is recommended to use 15A; M is the motor; the motor rotates forward when B1 is pressed, the motor reverses when B2 is pressed, and the motor brakes when B1 and B2 are both raised; Speed.
