Abstract:
    The invention relates to a magnetic suspension flywheel direct-current non-brush motor controlling system, wherein it comprises FPGA system, direct-current detecting feedback module, positioning sensor interface circuit, and power module; the FPGA module obtains request rotation speed from super machine, via sensor interface circuit and feedback module to obtain position signal and current signal, and the control algorism of FPGA, to calculate out the control value, and process reduction chopper PWM modulation, and amplify via amplifying module to generate the needed control current, and realize control accurately. The invention has low power consumption and high reliability.
