| Abstract |
Nonlinear current measurement errors producing torque ripple in direct torque controlled (DTC) permanent
magnet synchronous motor (PMSM) drives are analysed. In this paper the focus is on the
nonlinearity of Hall-effect current sensors and its effect on torque ripple. It is demonstrated that
nonlinear current measurement errors produce harmonics in the torque. |
