| Abstract: | A scheme of the chopper constant torque driver is presented in this paper which is based on a single chip and multi- channel DAC breakdown for 4 lines two-phase stepper motor. Sub-control strategy is specified and the hardware implementation of drive circuit about the chopper constant current is mainly discussed. Then the function diagram of hardware and software design is presented. This method can be applied to the numerical control electric pan&tilt to drive professional camera which can smooth the filmi... |
