Abstract
A rotating electrical machine apparatus comprising a motor generator 10 having a stator (11) to which a plurality of coil groups are provided and a rotor (12), and a control apparatus (30) which controls a current supplied to the coil groups of the stator (11), wherein the stator (11) is provided with a stator friction portion (21) and the rotor (12) is provided with a rotor friction part (19), and the rotor (12) is movable between a connection position, in which the stator friction portion (21) and the rotor friction portion (19) are in contact with each other and the rotor (12) and the stator (11) are connected with each other, and a separation position, in which the stator friction portion (21) and the rotor friction portion (19) are separated from each other, and is constituted to move to the connection position when at least two coil groups among the plurality of coil groups are simultaneously excited, and the control apparatus (30) controls a current supplied to the coil groups so that at least two coil groups among the plurality of coil groups are simultaneously excited when prescribed connection condition is fulfilled.
