| description | The invention discloses a fault detection system based on detection coil groups, which belongs to the technical field of motors, and is characterized in that each detection coil group in the system is formed by connecting a plurality of detection coils with the same or opposite magnetic field positions in series in a positive and negative manner; the sensor is used for sensing magnetic field changes in the motor and generating voltage signals. The short circuit detection module is connected with the plurality of detection coil groups and is used for detecting, positioning and removing a short circuit fault according to the voltage signal of each detection coil group and the rotor position; and the conventional detection module is connected with the plurality of detection coil groups and is used for detecting, analyzing and reporting a preset fault according to the voltage signal of each detection coil group and the position of the rotor.
