Design and analysis of double-stator permanent magnet brushless motor for hybrid electric vehicles

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. By using finite element analysis, the field distributions of the DSPMBL motor are obtained. The static characteristics of the proposed motor are also deduced. Based on these characteristics, the system mathematical model can be established. Hence, the evaluation of system performance is conducted by computer simulation.
