Title:
SYNCHRONOUS MACHINE DRIVE CONTROL DEVICE, AND VEHICLE EQUIPPED WITH SYNCHRONOUS MACHINE SUBJECTED TO DRIVE CONTROL BY SAID SYNCHRONOUS MACHINE DRIVE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/202625
Kind Code:
A1
Abstract:
Provided is a synchronous machine drive control device that can detect a rotation angle correction amount and enables the detection of the rotation angle correction amount in a wide range, even if a synchronous machine operates at a high rotation speed. An inverter control device (19) is provided with a rotation angle correction amount calculation unit (19h) that calculates a correction amount for a rotation angle of a synchronous machine (12). A three-phase short circuit is executed while the synchronous machine (12) is rotating, and the correction amount of the rotation angle is calculated on the basis of the current detected by a current sensor (20).
