  • Method for determining a fault in an electronically commutated electric motor
    Patent number: 10162009
    Abstract: The invention relates to a method for determining a fault in an electronically commutated electric motor, in which at least one stator coil of the electric motor is connected in parallel in each motor phase, in which a motor phase is energized and the current flowing through this motor phase is measured. In a method in which a defect in the electric motor is identified reliably, the three motor phases are energized one after the other and the current occurring during this energization of the individual motor phases is measured, wherein the currents measured in the three motor phases are compared with one another and a defect in the electric motor is identified if the measured currents differ from one another.
