The BLDC Motor Efficiency Improvement by Electronical Correction of the Power States Indications

In this paper an electronic correction of the symmetry of the states is proposed that determines the angular position of the BLDC motor shaft. The results illustrating the measurements of the asymmetry of the states of the Hall effect sensors determining the position of the motor shaft following from the adopted measuring system are presented. The improvement in efficacy by improving the symmetry of the power supply of the motor windings tested resulting from eliminating the asymmetry of signals from the sensors is shown.
