Claim:
A speed-controlled dynamo-electric compound system, comprising: at least one primary dynamo-electric unit (E 101 ) arranged to rotate a shaft (S 104 and/or S 105 ); a first centrifugal clutch (FC 101 ) having a driving side connected to the shaft (S 104 and/or S 105 ) and a driven side connected to an engine (ICE 101 ), wherein rotation of said dynamo-electric unit at a preset speed causes said driving side of the first centrifugal clutch (FC 101 ) to engage said driven side and thereby connect said engine (ICE 101 ) to said shaft (S 104 and/or S 105 ); a load connected to said shaft (S 104 and/or S 105 ) through an output device; a second centrifugal clutch (FC 102 ) arranged to engage said load when said first centrifugal clutch (FC 101 ) transmits power from said primary dynamo-electric device (E 101 ) to said engine (ICE 101 ) and a speed of said engine (ICE 101 ) is above a preset value, and to disengage said load when a speed of said engine (ICE 101 ) is below a preset value; a one-way transmission mechanism (SWC 101 ) arranged to transmit the rotary kinetic energy between said engine (ICE 101 ) and said load, and installed in a selected position of the transmission chain formed between engine (ICE 101 ) and the shaft (S 104 ) through the first centrifugal clutch (FC 101 ) and the second centrifugal clutch (FC 102 ); and to disengage said load when a speed of said engine is below a speed of the load side; and a secondary dynamo-electric unit (E 102 ) coupled to said engine (ICE 101 ), said engine driving the secondary dynamo-electric unit (E 102 ) to supply power to said primary dynamo-electric unit (E 101 ) and the electrical energy storage device (ESD 101 ) to jointly drive the primary dynamo-electric device (E 101 ) by the power from said electrical energy storage device (ESD 101 ) when power reverses of said electrical energy storage device (ESD 101 ) are above a preset value; and the secondary dynamo-electric unit (E 102 ) generates electricity to charge the electrical energy storage device (ESD 101 ) when the power reverses of said electrical energy storage device (ESD 101 ) are below the preset value.
