[0067] The present invention will be described in detail below in conjunction with the drawings and embodiments.
[0068] The invention provides a permanent magnet synchronous motor servo drive device, the structure is as figure 1 As shown, it mainly includes a controller 1, a power inverter 2, a current sensor 3, a position sensor 4, and a permanent magnet synchronous motor 5. The current sensor 3, position sensor 4 and power inverter 2 are respectively synchronized with the permanent magnet Motor 5 is connected. The controller 1 includes an FPGA control module 101 and a DSP control module 102, which are connected by a bus interface. The FPGA control module 101 is connected to the upper system 6 and receives the position given signal sent by the upper system 6. The FPGA control module 101 is connected to the current sensor 3 through the AD converter 7 to receive the current feedback signal, the FPGA control module 101 is also connected to the position sensor 4 to receive the po...
