<P>PROBLEM TO BE SOLVED: To provide a power transmission device that has a voltage regulation function of keeping a substantially constant DC voltage generated in the process of power transmission and output externally. <P>SOLUTION: A power transmission device 1 having power generation means 4 disposed on a driving rotary shaft 2 to generate an alternating current with rotation of the driving rotary shaft 2, an inverter 6 for rectifying the alternating current generated by the power generation means 4 once to a direct current, and then outputting a frequency conversion thereof, and motor means 5 for receiving the alternating current from the inverter 6 to generate a rotative driving force on a follower rotary shaft 3 includes: a DC supply section capable of externally outputting the direct current in the inverter 6; a voltage measurement section 8 for measuring a DC voltage in the inverter 6; and a frequency adjustment section 10 for changing the conversion frequency in the inverter 6 such that the value measured by the voltage measurement section 8 remains constant. <P>COPYRIGHT: (C)2013,JPO&INPIT |
