| Abstract: | This paper designs a current acquisition circuit of DC motor, it solves the problem of high speed acquisition of armature current. Using the Holzer current sensor, the current data is collected and sends to PC through serial port.It can be seen by LCD, and also can be showed in Labview software interface, so this design has practical engineering significance. |
