Abstract: A dynamoelectric machine includes: a winding; a stator core including a slot in which the winding is installed; a cover part that covers the stator core; and a crossing part that is a space formed between the cover part and the stator core, wherein, in the crossing part, an end portion of the winding in an axial direction is exposed, and a filling member is disposed between a side surface of the winding in a radial direction and an inner side surface of the cover part in the radial direction.

Abstract: An anomaly detection apparatus executes prediction processing to predict fluctuations of a normal range for a value of a parameter in a specified period, correction processing to identify an upper limit value at a local maximum point from fluctuating upper limit values of the predicted normal range, correct the upper limit values of the normal range, identify an upper limit value at a local minimum point from fluctuating upper limit values of the corrected normal range, and correct the upper limit values of the corrected normal range based on the upper limit value at the local minimum point identified, and anomaly detection processing to acquire a value of the parameter in the specified period, determine whether the value of the parameter acquired falls within the corrected normal range, and output predetermined information when determining that the value of the parameter acquired does not fall within the corrected normal range.
