Self-Sensing Sinusoidal Drive for Spindle Motor Systems

Traditionally, spindle motor systems are driven with Brushless DC (BLDC) drive. This drive, however, suffers from torque pulsations which is undesirable from the perspective of motion control and acoustics. In this paper, a self-sensing sinusoidal drive for spindle motor systems is proposed. The dri...

Description
Summary:Traditionally, spindle motor systems are driven with Brushless DC (BLDC) drive. This drive, however, suffers from torque pulsations which is undesirable from the perspective of motion control and acoustics. In this paper, a self-sensing sinusoidal drive for spindle motor systems is proposed. The drive comprises of (1) an optimal angle sinusoidal drive, (2) an innovative lossless current sensing for self-sensing methodology, (3) a self-sensing sinusoidal drive. The drive introduced was implemented on FPGA and its results are presented.
