摘　　要：提出了一种井下PMSM电机轴角测量系统,该系统采用数字信号处理器TMS320F21812将旋转变压器输出的模拟信号转化为数字信号,给出了系统测量原理和设计方案。试验结果表明:该方案解算精度高,系统运行稳定,完全满足井下仪器对电机轴角测量的技术要求。-A method of detection the rotor position of the downhole permanent magnet synchro- nous motor is presented and the digital signal processor TMS320LF2812 is introduced to trans form analog signals of resolver to digital signals. The measuring principle is particularly analyzed and the design of system circuit is also given. The experiment show that the system has high relia bility,it can efficiently realize the position control with stable running of whole system, and can satisfy requirements of high accurate measuring system of Shaft Angle of petroleum downhole tools.
