Abstract:
A drive system of an embodiment includes an inverter for driving an electric motor; a detector that detects an electric current value output from the inverter; command generators that generate an electric current command value corresponding to an electric current to be supplied to the electric motor and a gate command of the inverter so that the electric current command value matches the electric current value; calculators that calculate an voltage target vector of the inverter and a rotation phase estimation value of the electric motor based on the electric current value and the voltage target vector, in an initial estimation of when activating the inverter. The electric current command value in the initial estimation is a value to supply an electric current for magnetically saturating a rotor of the electric motor, and a dynamic inductance of the electric motor used for calculating the rotation phase estimation value is a value of when the rotor of the electric motor is magnetically saturated.

Claim (Index 9):
The inverter according to  claim 7 , wherein the electric current command value comprises an electric current amplitude command and an electric current phase command, and\n when an estimation completion flag output from a host controller rises after the initial estimation is ended, and a power running flag also rises, the electric current phase command becomes a value later than the initial estimation time, and when the estimation completion flag output from the host controller rises after the initial estimation is ended, and a regeneration flag also rises, the electric current phase command becomes a value preceding the initial estimation time.
