The paper presents a surface mounted permanent magnet synchronous machine (SMPMSM) with distributed windings. The main focus of the paper is to provide a new calculation method of electric machine losses, including copper losses and iron losses at load. This method based on the separation of injected current in d-q axes and the developed iron loss models expressing the dependence between the fl...

Abstract—This paper proposed an estimation approach of temperature rise in stator winding and rotor magnet of a surfaced-mounted permanent magnet (PM) AC motor. By using the 3rd-order extended Kalman filter (EKF) algorithm in rotating reference frame, stator winding resistance and rotor PM flux-linkage can be estimated independently. After comparing the estimation results of resistance and flux...

Abstract Optimal design results in maximum motor performance. This type of BLDC has undergone innovations such as surface-mounted permanent magnet (SPM) with variants as: radial magnet, rectangular and bread-loaf. The position the outer rotor is a that commonly applied to electric bicycles. attached side body allows for superior torque In this paper, we present an analysis on bicycle been imple...

This article presents the process of building a hybrid analytical model (HAM) for surface-mounted permanent-magnet machines. The HAM couples reluctance network (RN) in stator region with magnetic scalar potential air gap and magnets regions. can deal slotting effect straight teeth, takes saturation into account iron material using RN model. It is calculated under open-circuit loaded conditions....

This article deals with I-f control of surface-mounted permanent magnet synchronous machine (SPMSM) drives. Conventional open-loop is poorly damped and can only operate stably positive $d$ -axis current. An a new current compensation lo...
