Abstract: The principle of twin-rotor permanent magnet brushless DC motor was researched in the paper,then the position detect method was analyzed in detail.On the basis of the preceding study,the motor controller which made use of digital signal controller as the core chip and CPLD as the auxiliary processor was designed,ultimately the close-loop speed regulation of twin-rotor permanent magnet brushless DC motor was realized.Mostly the hardware design part was expatiated in the paper.
