DEVICE FOR DETECTING LEAKAGE FLUX

摘要

PURPOSE: A leakage flux detection device is provided to promptly grasp abnormality of a winding of a rotor and a position of abnormality occurrence. CONSTITUTION: A leakage flux detection device(100) includes a first detection sensor(120), a second detection sensor(130), a base unit(140) and signal comparison unit(190). The first detection sensor and the second detection sensor are arranged in both sides of a rotor with having a rotor in between and detect leakage flux generated from the winding of the rotor. The first detection sensor and the second detection sensor are inserted in the base unit and are arranged to be in the both sides of the rotor. The signal comparison unit compares received signals detected from the first detection sensor and the second detection sensor and confirms abnormality of the winding of the rotor through the compared result.
