초록

This study proposes the mitigation method of shaft voltage by varying the parasitic capacitance. First, the shaft voltage explained. Second, the parasitic capacitances causing shaft voltage are analyzed respect to geometry of motor and windings. Then, the equivalent circuit is established to obtain the shaft voltage and output torque characteristic and develope appropriate motor structure. Finally, simulation and experiment are conducted to verify that modified motor suppress the shaft voltage. This novel model does not require additional hardware.
