摘要

"The drive motor of DC reversu00ecvel including a converter DC / DC and DC / DC controller of four quadrants.A reversible drive DC motor (440) includes a DC / DC converter (60) having an input (CC (66, 78),A first outlet (78) and a first voltage CC in pulses and a first value of voltage CC, a second output (102) and a second voltage CC in pulses and second value of DC voltage.And a third output (110) having a third voltage DC in wrists and third voltage value DC.The first and second outlets (78, 102) are adapted for interconnection with electrical terminals of the armature (138, 140) of a DC motor (134, 62,450) and the third output (110) is adapted for electrical interconnection with a terminal field (146) of the engine.A routine of the microprocessor (362) calculates motor speed from the armature voltage, field current and armature current of the motor.An external control loop (246) for the speed of the motor and two loops of the internal control controllable separately (250,346) for armature and field current control of the DC / DC converter responsive to the engine speed is calculated and a reference speed (352) to independently control the three values.DC voltage.
