“…It is worth mentioning that the same cooling duct can be used for alternate cooling methods such as water cooling in the future. In addition, comparison of conventional FSMs without a cooling duct [10,24] shows that the temperature distribution in the stator of the proposed design is reduced with the addition of a cooling duct. Comparison reveals that conventional design without a cooling duct shows a stator temperature of 50 ℃, whereas the proposed design with a cooling duct exhibits a maximum of 44 ℃ in the winding portion of the stator slot.…”

Compact stator structure of flux switching machines (FSMs) encompassing both permanent magnets (PMs) and armature winding slots (AWS) attract research interest whenever high power and density are the basic requirements. However, it also results in temperature rises owing to heat generation by electromagnetic power losses degrading the electromagnetic performance and affecting machine performance. In this study, a segmented permanent magnet (SPM) consequent pole FSM (SPM-CPFSM) is developed, which provides a stator cooling channel (duct) for improved heat dissipation to avoid demagnetization of PM as well as overheating. Furthermore, this study investigates detailed electromagnetic performance analysis and prediction of temperature variation in various machine parts owing to the heat generated by iron, copper, and magnet eddy current losses utilizing coupled electromagnetic-thermal analysis accounting for magnetic flux density variation. In comparison with the 2D analysis, the developed 3D coupled-field analysis more accurately predicts electromagnetic performance and temperature distribution. Analysis reveals that a cooling duct at the stator significantly assists in stator heat dissipation in the axial direction ensuring a safe operating condition of the PMs as well as machine parts to avoid overheating.

Abstract-This paper presents a composite sliding mode control (CSMC) method for speed control of surface-mounted permanent magnet synchronous motors (SPMSMs). The proposed CSMC consists of a new sliding mode control (SMC) based on a novel hybrid reaching law and an extended sliding mode disturbance observer (ESMDO). The new hybrid reaching law is composed of two parts, a terminal reaching part and an exponential plus proportional reaching part. It can effectively suppress the chattering and reduce the reaching time, compared with the conventional constant plus proportional rate reaching law (CPRL). The ESMDO is designed based on CPRL. It can estimate the extra chattering produced by the drive system's lumped disturbance and compensate for the controller's output. Based on the proposed new SMC and ESMDO, an antidisturbance sliding mode speed controller is designed to improve the performance of SPMSM drive systems. The performance of the proposed method has been validated experimentally and compared with the CPRL-based SMC methods under different conditions.

“…Compared to the three-phase permanent-magnet synchronous motor (PMSM) drives, the dual three-phase PMSM drives have received considerable interests by the merit of lower DC-link current ripple [1], reduced torque ripples [2], and better fault tolerance capability [3][4]. The high-performance dual three-phase PMSM drives can benefit from the accurate and updated knowledge of rotor flux linkage [5][6].…”

The rotor flux linkage of permanent-magnet synchronous motor (PMSM) is of great importance for monitoring and high-performance control. However, most of the existing online estimation methods need prior knowledge of other PMSM parameters such as stator resistance and dq axis inductance, which are difficult to realize in the rank-deficient models of electrical machines. This paper proposes a simple online estimation method of rotor flux linkage for the dual threephase surface-mounted PMSM (SPMSM) drives with the assistance of injected position-offset. The independent estimation model has been developed for the rotor flux linkage by appropriate setting of positon-offset between two sets of threephase windings of dual three-phase SPMSM drives. The proposed method not only has little influence on the output torque and high signal-to-noise ratio for observation, but also offers the superior performance in estimation accuracy irrespective of the influence of VSI nonlinearity. In addition, the proposed position-offset based method is suitable for the fullspeed region including the field-weakening operation. Finally, comprehensive experimental results are presented to verify validity of the proposed method under different working conditions. 1 Index Terms-Dual three-phase SPMSM drive, rotor flux linkage, parameter estimation, position-offset, VSI nonlinearity.
