Embodiment 1
[0028]Embodiment 1, a detection system for the rotor magnetic pole position of a spliced arc motor for a large astronomical telescope. The spliced arc motor is a self-developed multi-pole permanent magnet synchronous motor. The present invention is designed to detect the rotor magnetic pole position of the spliced arc motor The system requires fast, simple and real-time detection of the rotor magnetic pole position of the permanent magnet synchronous motor. The vector control method is used to control the three-phase current amplitude and phase of the stator winding according to the precise position of the rotor magnetic pole measured in real time, so as to ensure the large-scale astronomical The telescope drive system runs smoothly.
[0029] The system first subdivides and anti-interferences the incremental encoder signal with multiple reference points, and sends it to the encoder signal processing interface of the DSP, which is converted by the DSP into the precise posi...
