PROBLEM TO BE SOLVED: To enable voltage control in a motor-generator apparatus that includes a motor-generator using a permanent magnet for a field.SOLUTION: A motor-generator apparatus 1 includes: a drive source; first and second motor-generators 3, 4 each using a permanent magnet for a field; and a planetary gear mechanism 2 that includes a ring gear 17 coupled to a first rotor 27 being a rotor of the first motor-generator; a sun gear 16 coupled to a second rotor 37 being a rotor of the second motor-generator; and a planetary carrier 18 coupled to the drive source. Further, in order to control a voltage generated by one of the first and second motor-generators, at least one of a rotation speed of the other of the first and second motor-generators and a rotation speed of the drive source is changed so as to control a rotation speed of the one of the first and second motor-generators. |
