IPMSM with more than 10KW, which is used for HEV, has lower Ld-Lq since a groove was made on the Q-axis flux path of the rotor to reduce the eddy current loss in the permanent magnets. Therefore, a high reluctance torque and wide operating range can't be expected. Also in the winding layout, concentrated winding may widen the operating range; however this is needed the fractional slot or leads to...
The performance of hybrid motor directly affects hybrid vehicle performance and fuel economy. In this paper, doubly salient permanent magnet motor is selected as vehicle motor of small displacement ISG mild hybrid. Magnet field superposition method is proposed to analyze the static characteristics of doubly salient permanent magnet motor. Namely, the "partition method" is adopted to analyze...
Flux-switching permanent magnet (FSPM) motor is a relatively novel brushless machine having magnets and concentrated windings in the stator instead of the conventional rotor-PM topology, which exhibits inherently sinusoidal PM flux-linkage, back-EMF waveforms and high torque capability. However, since the airgap field is produced by the stator-magnets alone, it is difficult to be regulated. Hence,...
This paper presents the design and analysis of a new double-stator permanent brushless (DSPMBL) motor for hybrid electric vehicles. The corresponding output power equation is analytically derived. The initial calculation of motor dimensions and parameters, including the core diameter, stack length, permanent magnet size and winding connection modes, are also discussed. A DSPMBL motor is designed....
