POWER TRANSMISSION DEVICE

摘要

PROBLEM TO BE SOLVED: To enable driving of load while controlling an operation status of a motor without causing complication of a configuration and high cost of a power transmission device.

SOLUTION: A rotating magnetic field is generated by flowing an induced current to a rotor coil 30 caused by occurrence of rotation difference between an input side rotor 28 and an output side rotor 18 and torque acts between the input side rotor 28 and the output side rotor 18. A rectifier 93 rectifies AC power from the rotor coil 30 taken out through a slip ring 95 and a brush 96, and a boosting converter 94 boosts and outputs the power rectified with the rectifier 93. An electronic control unit controls a boosting ratio in a boosting converter 94 so as to make a rotation speed of the engine to nearly meet a target rotation speed based on the engine torque.
