Abstract:
A control device of a synchronous electric motor includes: the synchronous electric motor with three-phase stator windings Y-connected; a detection unit that detects a neutral point potential which is a potential at a Y connection point; and an inverter that drives the synchronous electric motor. The control device of the synchronous electric motor which controls the synchronous electric motor using the inverter, includes a measurement mode in which the neutral point potential is detected in a state in which the synchronous electric motor is energized by an AC current and controls the synchronous electric motor based on a value of the neutral point potential detected in the measurement mode.

Claim (Index 11):
The control device of the synchronous electric motor according to  claim 1 ,\n wherein during driving when the synchronous electric motor is normally driven after the neutral point potential is detected in the measurement mode, the neutral point potential is detected to detect the neutral point potential by applying a voltage pulse for neutral point potential detection by the inverter, a rotation position of the synchronous electric motor is estimation-operated from a value of the detection and a value of the detected neutral point potential in advance, and the synchronous electric motor is driven based on the rotation position.
