An efficient method for single-plane rotor balancing which requires some components of the electric signal spectrum from each phase of the electric motor to which it is directly coupled is developed. The signal readings, which are scalar quantities that reflect residual complex values (offset with magnitude and phase) when there is no imbalance, produce a nonlinear behavior of the data with respect to the unbalanced forces. This requires an algorithm to determine, based on readings of residual values for the balanced condition, and the imbalanced rotor, the complex values that directly relate to the imbalance. The signal errors that are present in the readings, more pronounced in these Hall-type sensors, are decreased by means of a system of equations of perturbations and compatibility relations that are applied to these data. This algorithm was verified by running several study cases, with the same order of precision of the traditional balance method that uses vibration data. The alternative approach presented in this paper may offer an advantage in recording and monitoring of the rotor imbalance
