Abstract
The high torque peaks commonly found in single-phase brushless dc motors can be compressed by different driving methods, which are proposed and studied based on finite-element analysis (FEA). It is concluded that one dead-zone can be added into the driving signals to improve current waveforms and torque envelope. The test results show that the noise level and performances are greatly improved when one proper dead zone is implemented
