Avnet Spartan-6 FPGA马达控制开发方案(AES-FMC-MC1-G)

Avnet Spartan-6 FPGA马达控制开发方案(AES-FMC-MC1-G)

FMC模块是和Xilinx Spartan-6 LX75T FPGA基板一起使用的,具有低引脚数,能直接插入Avnet 或Xilinx的FMC平台,能驱动步进马达,有刷DC马达(BDC),无刷DC马达(BLDC)和永磁同步马达(PMSM),集成了TI公司的马达驱动器和高精度检测的Delta-Sigma ADC,主要用于工业自动化,消费类电子,医疗诊断和机器人.本文介绍了马达控制模块主要特性,方框图,电路图和材料清单。High demands are being placed on motors used for industrial automation, consumer electronics, medical diagnostics and robotics. Xilinx FPGAs deliver the performance and integration required to execute complex motor control algorithms, increased efficiency, integration and custom safety features, often outside of the capabilities of traditional MCUs.As a companion to the Xilinx Spartan-6 LX75T FPGA base board, Avnet’s Motor Control FMC Module features the Low Pin Count (LPC) form factor, enabling attachment to any Avnet or Xilinx FMC-enabled platform. Each Avnet Motor Control FMC can drive one Stepper, two Brushed DC (BDC), two Brushless DC (BLDC) or two Permanent Magnet Synchronous Motors (PMSM).The Avnet Spartan®-6 FPGA Motor Control Development Kit is an ideal platform for designers seeking to experiment with proven reference designs and develop custom control integrated with flexible peripheral functions like Ethernet, PowerLink and PCI Express. The Motor FMC module implements Texas Instruments integrated motor drivers and high precision Delta-Sigma modulators for voltage and current sense. Designers also have the option to use the Xilinx XADC integrated 12-bit data converter available in new 7 Series devices for the ultimate integrated design. A prototyping area for experimenting with alternate front end circuitry is also provided. Stepper, Brushed DC (BDC), Brushless DC (BLDC), and Permanent Magnet Synchronous Motors (PMSM) can be driven by the FMC module, under control of the Spartan-6 LX75T FPGA on the baseboard. The included reference designs provide great demonstrations and starting points for your own design.图1.马达控制模块外形图马达控制模块主要特性ow Pin Count (LPC) form factorPlugs into any Avnet or Xilinx FMC-enabled platformDrive Stepper, Brushed DC (BDC), Brushless DC (BLDC) and Permanent Magnet Synchronous Motors (PMSM)Spin two motors (12-24V) simultaneously under FPGA controlTexas Instruments Integrated Motor DriversTexas Instruments Delta-Sigma ADCs for high precision sensingXilinx XADC header enables low-cost 7 Series FPGA integrationHall Sensor/Encoder and GPIO portsUser prototyping areaPowered from FPGA baseboard or external sourceIncludes 1 Portescap BLDC and 1 Stepper motor图2.马达控制模块方框图图3.马达控制模块电路图(1)图4.马达控制模块电路图(2)图5.马达控制模块电路图(3)图6.马达控制模块电路图(4)图7.马达控制模块电路图(5)图8.马达控制模块电路图(6)图9.马达控制模块电路图(7)图10.马达控制模块电路图(8)图11.马达控制模块电路图(9)马达控制模块材料清单(BOM):
