| Abstract: | A kind of driving and decoding circuit based on AD698 is main designed,the circuit structure is simple, the excitation signal for resolver is produced by using the AD698 signal disposal added simple external components.The signal decoding uses AD698 chip A channel as the main control port,the B channel as a signal conditioning port,the angle signal is collected through the signal demodulation,and the standard signal is collected by A/D acquisition card.The driver decoding circuit board has been successfully used in a test of steering gear brushless DC motor for speed measuring devices. |
