Document Type and Number:
WIPO Patent Application WO/2019/135293
Kind Code:
Provided is a rotary electric machine device in which it is possible to make a rotary electric machine output a torque even if one of the direct-current power sources has failed, and in which it is possible to appropriately change the characteristics of the rotary electric machine in accordance with changes in the direct-current power source voltage. This rotary electric machine device (1) comprises: a power source switching mechanism (23) that switches and outputs low-voltage direct-current power and high-voltage direct-current power; a winding connection switching mechanism (24) that switches the mutual connection of a plurality of phases of windings between a first winding connection state and a second winding connection state in which the induced voltage constant of the windings becomes lower than that in the first winding connection state; an inverter (12) including a switching element; and a control device (25) that drives the switching of the power source switching mechanism (23), drives the switching of the winding connection switching mechanism 24, and drives the switching element so as to be turned on and off.
