In one embodiment, the current sampling circuit 20 includes a current transformer CT1, a resistor R2, a rectifier bridge D2, an electrolytic capacitor EC4, a capacitor C5, a resistor R4, a resistor R1, a capacitor C1, and a rectifier bridge D1. When current flows through the live wire L, the current running current of the motor 10 can be sampled through the current transformer CT1, that is, the current transformer CT1 converts a large primary-side current at the L end of the live wire into a small secondary-side current according to the electromagnetic induction principle, the product of the small secondary-side current and the resistor R2 is the current running voltage of the motor 10, the passing alternating current is converted into direct current through the rectifier bridge D2, then the electrolytic capacitor EC4 and the capacitor C5 stabilize the voltage of the collected electric signal and eliminate high-frequency interference, the resistor R1 and the capacitor C1 form an RC filter circuit, which also plays a role in attenuating high-frequency signals, the controller 30 receives the electric signal output by the current sampling circuit 20 and performs signal processing on the received electric signal, so that the electric signal is converted from an analog signal into a digital signal, and the current running current of the motor 10 is obtained.

The preset average value, the preset variance and the preset current value can be flexibly set according to actual conditions.
It should be noted that, according to the unstable characteristic of the operating current curve of the motor when the dynamic balance of the motor is damaged, a plurality of position points are selected from the operating current curve at random or at intervals of a preset time, a difference between every two adjacent operating currents on the operating current curve is determined to obtain a plurality of current difference values, and when the average value of the plurality of current difference values is greater than or equal to the preset average value, the variance of the plurality of current difference values is greater than or equal to the preset variance, and/or the maximum current difference value of the plurality of current difference values is greater than or equal to the preset current value, it is determined that the dynamic balance of the motor is damaged. The automatic detection of the dynamic balance of the motor operation is realized, when the dynamic balance of the motor is damaged, the performance of the cigarette machine is determined to be attenuated, and the accuracy and the intelligence of the performance attenuation detection of the cigarette machine are improved.
