Abstract :
This paper presents the design, analysis, and sensorless control of a new self-decelerating permanent-magnet (PM) machine based on magnetic-gear. The key is to integrate the magnetic gear with the PM machine while removing the gear inner rotor. Hence, the proposed motor can achieve the low speed high torque output and high speed compact design requirements as well as high torque density with a simple structure. By using the finite element analysis (FEA), the static characteristics of the proposed motor are analyzed. In order to resolve the problems of using the mechanical sensors, various sensorless control algorithms for estimating rotor speed have been proposed. A method of model reference adaptive system (MRAS) for sensorless control of this new self-decelerating PM motor is described, and the simulation results demonstrate the validity of this proposed algorithm.
