Abstract:
    The invention involves in a kind of electrical power equipment. It consists of a speed control unit (SC), two currency control units (CC), two PWM generation units (PG), two reverser units (RV), two current testing units (CT) and a position-testing unit (PT). SC produces the current references for the torques of two motors respectively. CC produces the control voltage reference. PG produces the driving signal for RV. RV drives the permanent magnetic synchronous motor. CT is used for currency feedback. PT is used for speed position feedback. This vector control system of differ- frequency supply permanent magnetic synchronous motor is an effective control means for corresponding two co-axis permanent magnetic synchronous motors. The invention can be used for controlling special motors with hi power density twin stator and twin rotator.
