This paper presents a study on brushless permanent magnet (PM) slotless motor with toroidal winding (TWSL). Herein, slotted motor with conventional winding (i.e., CWS motor), which has already been applied to the industry, is compared to the TWSL motor. A finite-element analysis is used to comprehend the operation basis of the TWSL motor, including the linkage flux, back electromotive force, and torque...
A proposed novel double-barrier design with single-layer IPMSM is well proved to be effective for reducing pulsation torque, torque ripple and cogging torque, in published work, in which the torque characteristics be sensitive to the unique "connected" double-barrier structure is generally studied. This extended paper presents a few specific models for examining the effect of design variables...
In this paper, the design methodology of a rotor for the interior permanent magnet motor (IPMSM) considering pole-arc to pole-pitch ratio and saliency parameter owing to PM and duct structure is proposed in order to improve the characteristics such as average torque, torque ripple, cogging torque and back EMF waveform. Especially, demagnetization effect due to duct design is analyzed by using the...
Interior PM synchronous motors (IPMSMs) are used in many industrial and home appliance applications due to their advantages. However, the torque ripple and cogging torque of IPMSM are generally greater than those of surface permanent magnet synchronous motor. Furthermore, the IPMSM with concentrated winding is more disadvantageous than that with distributed winding in the respects. The problems are...
A study on magnetic force is more important than other factors, because acoustic noise of motors is mainly affected by vibration of structure. Especially, harmonics of normal force are associated with resonant frequency of structure. Therefore, although cogging torque and torque fluctuation influenced by tangential force are important factors in output characteristic, the normal force is more important...
