Abstract
There is provided herein an electrical motor and associated motor drive. The motor comprises an output shaft, and a speed sensor configured to measure the speed of the output shaft. The motor drive comprises a controller configured to output a current demand for the motor based on a speed error between a desired speed of the output shaft and the measured speed of the output shaft, and a feedback signal of the output current demand scaled by a first gain.
