Abstract
An oil leak detection device includes a pair of permanent magnets, a plurality of commutators, a coil, a pair of brushes, and a current sensor. An N-pole and an S-pole of the pair of permanent magnets face each other. The plurality of commutators are attached to an output shaft. The coil is wound onto the output shaft inside the pair of permanent magnets in the radial direction of the output shaft. The coil is electrically connected to the plurality of commutators. The pair of brushes are attached to a housing and are capable of coming into contact with each of the plurality of commutators. The current sensor detects an induction current flowing between the pair of brushes and the housing.
