摘要： PROBLEM TO BE SOLVED: To improve a torque transmission capacity of a power transmission device. SOLUTION: A rotation difference is generated between a first and a second rotor 28, 78 and a third rotor 18, which causes a rotary magnetic field due to an induced current flowing in a first rotor winding 30. This causes a torque functioning between the first rotor 28 and the third rotor 18. The rotary magnetic field generated by the induction current flowing in a second rotor winding 80 functions on a second stator 66, which in turn generates an induced electromotive force in a second stator winding 70. The induced electromotive force is supplied via a phase adjustment circuit 43 to a first stator winding 20, which generates a rotary magnetic field and causes torque functioning between the first stator 16 and the third rotor 18. The rotary magnetic field generated by the second rotor winding (80) and the induced current flowing in the second stator winding (70) cause a torque functioning between the second stator (66) and the second rotor (78).

摘要： PROBLEM TO BE SOLVED: To provide a brush abnormality detector for a rotary electric machine that can detect abrasion of a brush by using an existing electrical circuit.SOLUTION: When a brush 5a is abrading away, a moving contact point 7a fixed to the brush 5a approaches to a slip ring 4a, and finally comes into contact with the slip ring 4a. When a switch 10 and a switching element S4 are turned on under this state, current from a battery 9 successively flows through the switch 10, the moving contact point 7a, the slip ring 4a, the brush 5a, an output terminal Pu and the switching element S4. At this time, the current is detected by an ammeter 11, and the detection value is transmitted to ECU 13. Upon the current detection of the ammeter 11, ECU 13 determines that any one of brushes 5a, 5b, 5c is worn, and actuates an alarm device 14.
