PMSM controller based on profinet

The utility model relates to an electric machine the controller, concretely relates to PMSM controller based on profinet. A PMSM controller based on profinet, includes DSP treater and the photoelectric encoder acquisition circuit who is connected with the DSP treater, power bridge drive power supply, detecting element, power tube protected location and CAN communication unit, still include the profinet communication unit who is connected with the DSP treater. The utility model discloses a profinet communication technology is realized to the ERTEC200 chip, and this technique real -time is strong, the interference killing feature is strong, more preferably, the DSP treater adopts the MS320F2812 chip, realizes PMSM's space vector control, saves a large amount of control cable, practices thrift the cost.
