(57) Abstract :
The present invention discloses a control system for making an input power vary with load and rotating speed concurrently by
dragging multiple motors with one inverter bridge, which is consisted of a stator voltage-regulating unit, an electric motor unit, a
rotor speed-regulating unit, an inverter bridge unit, a controlling and driving unit and a signal processing unit. In the invention, by
setting a power factor sensor, the phase voltage and phase current of a motor stator are collected as a control signal to regulate an
input power and make it vary with the load; at the same time, by setting a voltage sensor and a current sensor, the motor rotor
phase voltage, the rectifier output voltage, the over voltage protection current and the chopper working current are respectively
collected as a control signal to regulate the input power and make it vary with the rotating speed. In the invention, a plurality of
microprocessors are employed for operating and controlling, a structural design of shunting function-modularized circuit is
developed, the interface standard and the interpolated signal processing technology are specified, therefore, by combining simple
and clear mechanical structures and system software, the effective feedback of energy can be realized, and the object of saving
power sources can be obtained.
