Example Embodiment

[0012] As shown in the figure, the present invention includes DSP, drive circuit, current acquisition circuit, encoder, brushless DC motor, inverter bridge, rectifier filter circuit, power supply, LED display, DSP and drive circuit, current acquisition circuit, encoder The LED display is connected, the brushless DC motor, the inverter bridge, the rectifier filter circuit, and the power supply are connected in sequence, and the inverter bridge is respectively connected with the drive circuit and the current acquisition circuit.

[0013] The model of the DSP is TMS320LF2812. In addition to realizing signal acquisition, calculation processing and control algorithm execution, DSP is also responsible for real-time communication with the host computer and completes other control functions of the system. The A / D module converts and processes the phase current signal as the feedback signal of the current loop. In this system, a photoelectric encoder is used instead of the Hall sensor t
