Suspension field mill probe

The invention discloses a suspension field mill probe which comprises a motor, a current collection rotor, a current collection stator and a reference signal generation unit. The current collection rotor comprises two metal induction conductors, and the metal induction conductors are driven by the motor to be repeatedly and alternately exposed in an electric field and generate induction charges. The collector stator converts the inductive charge into a current signal. The reference signal generation unit generates a reference signal having the same frequency as the rotation frequency of the motor when the motor drives the two metal induction conductors, so as to obtain an electric field value according to the current signal and the reference signal. Consumable materials such as a conductive slip ring do not need to be adopted, the manufacturing procedures and the element usage amount of the suspension field milling probe are saved, and low cost and miniaturization of the suspension field milling probe are ach
