Abstract :
For the reduction of acoustic noise and vibration generated in self-sensing brushless dc motor operation, a self-sensing quasi brushless DC drive (QBLDC) mode is presented. The structure of the drive and the related algorithms are introduced in detail in the paper. The drive can be implemented on field programmable gate arrays (FPGA). The performance of the drive presented has been confirmed by the testing results of the spindle motor used in hard disk drive.
