摘要： An electric rotating machine includes a rotor, a stator in which a coil is so wound as to have an coil end, and a coolant supply pipe. The coolant supply pipe lies with a length thereof extending substantially parallel to an axis of rotation of the rotor and is disposed above the stator in a direction of gravitational force. The coolant supply pipe has a first and a second coolant outlet through which coolant is to be emitted to the coil end. The first and the second coolant outlets are so oriented as to direct streams of the coolant to a first area and a second area of the coil end which are different in location from each other. This enables the coolant to be emitted to almost the whole of the coil end even when the electric rotating machine is titled in a direction in which the rotor turns.

摘要： An electric rotating machine is provided which includes a stator in which a coil is so wound as to have an coil end and a coolant channel. The coolant channel has defined therein a flow path through which coolant flows and a flow separator disposed in the flow path and a first and a second coolant outlet. The flow separator works to separate a flow of the coolant into at least a first and a second coolant streams. The first coolant outlet communicates with the first coolant stream, while the second coolant outlet communicates with the second coolant stream. The first and second coolant outlets drain the coolant to different portions of the coil end, thereby cooling almost the whole of the coil end even when the electric rotating machine is tilted undesirably.

摘要： A discharge amount measuring device includes a power source, first and second sensors, a calibration wire, and a measuring portion. The power source applies a voltage to a coil of a rotational electric machine. The first sensor detects a current flowing through the coil. The calibration wire has an end connected to the coil. The second sensor detects a current flowing through the calibration wire. The measuring portion forms a calibration line based on a first waveform detected by the first sensor and a second waveform detected by the second sensor. The measuring portion calculates a discharge amount based on the calibration line.
