When system is in the operation with closed ring state, owing to causing two powers of motor, reasons such as electronic device and mechanical aspects distribute when unbalanced, for example:
Bigger than normal when No. 1 power of motor, when No. 2 powers of motor are less than normal, the big sub No. 2 rotor electric currents of the electric current of No. 1 rotor, behind differential wave comparator loop, take out the difference signal of two rotor electric currents, be input to separately signal amplifier loop respectively and carry out voltage amplification and power amplification after 2 outputs of A and B, low-potential signal of A point output, high potential signal of B point output.Because A point current potential reduces, make No. 1 motor inverter bridge inversion angle reach, No. 2 rotor electric currents are increased, motor speed increases.Because B point current potential raises, move after making No. 1 motor inverter bridge inversion angle, No. 1 rotor electric current is reduced, motor torque reduces, power decline.After No. 1 motor is equal with No. 2 powers of motor, reach poised state, belt feeder stable operation.
