This work is a perfect replacement for an analog tachometer. An electronic flash or stroboscope is used, which equalizes the frequency of flashes with the frequency of rotation of the rotor. In this way, the impression that the rotor has stopped during the rotation of the motor is obtained, and the obtained frequency is used to calculate the actual rotation speed of the motor.
