DISCHARGE AMOUNT MEASURING DEVICE AND METHOD FOR ROTATIONAL ELECTRIC MACHINE |
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.
