3、 generally the power the situation, is also widely applied in the precision machinery and so on needs the high performance electric drive in the equipment, with controls the position, the speed, the acceleration, the pressure, the tensity and the torque and so on. What this article elaborates is “V-

4、M double closed loop irreversible cocurrent velocity modulation systems design”. The main circuit design is rests on the thyristor - electric motor (V-M) the system composition, Its system by rectification transformer TR, the thyristor rectification speeder, flat wave reactor L and the electric motor - power set and so on is composed. After rectification transformer TR and the thyristor rectification speeders function is the alternating current rectification which, inputs turns the direct cu
