Abstract
This paper presents a sensorless DTC of a new self-decelerating permanent-magnet (SDPM) wheel motor at full speed range. The problems in conventional DTC including large torque ripples, big d-axis current when the motor operates at light or sudden increased loads, and the poor estimation performance of rotor position at full speed range are solved. The proposed algorithm is verified with simulation results.
