Comparison of Different Winding Configurations for Dual Three-Phase Interior PM Machines in Electric Vehicles

Abstract

In this paper, two dual three-phase winding configurations are compared based on the Toyota Prius 2010 interior permanent magnet (IPM) machine. It is found that the winding configuration with single-layer full-pitched (SF) windings can improve average torque and reduce torque ripple in constant torque range. The winding configuration with double-layer short-pitched (DS) windings has better torque performance in a constant power range. The electromagnetic performances of the two winding configurations when one winding set is excited and the other one is open-circuited are also compared. The DS winding configuration shows much better performance under this condition. Overall, the dual three-phase winding configuration with DS windings is preferred for dual three-phase IPM machines in electric vehicles. A Toyota Prius 2010 IPM machine equipped with DS windings was manufactured to verify the analyses presented in this paper.

Review of Electric Vehicle Charging Technologies, Standards, Architectures, and Converter Configurations

“…In two-stage chargers, the battery powers the traction machine through an inverter and a PFC circuit and AC-DC converter are implemented between the motor and the electricity grid. A comparison of different winding configurations in EVs is presented in [184] and hairpin winding for electric motors are evaluated in [185]. The fast three-phase charging has been proposed in [186] which AC three-phase mains are linked to the middle point of each motor winding through an EMI filter and protection component.…”

Comparative Study of Permanent Magnet, Conventional, and Advanced Induction Machines for Traction Applications

“…For a fair comparison, the Toyota Prius 2010 IPM machine is directly adapted by applying the optimal specifications [21,32], and the IMs are designed with the same geometric dimensions and pole number. It is worth mentioning that Toyota Prius 2010 IPM machine has been used since all specifications and data for the Prius 2010 are fully available.…”

“…However, other models are still not available because of the confidential issues of the company. On the other hand, some essential geometric and operating design specifications of electrical machines for traction applications can be found in [21][22][23][24][25][26]. Furthermore, the IPM machine and the CIM share the identical stator slot/pole number combination (48S/8P) and winding layout with 5-slot pitch single-layer windings.…”

Multiphase Stator Winding: New Perspectives, Advanced Topologies, and Futuristic Applications

“…The proposed method has been validated by generating optimal winding configurations for five-phase 50-slot/48-pole SPM machine. Finally, In [88], the performances of a 48-slot/8-pole IPM machine with several six-phase winding configurations; namely, single-layer full-pitched (presented in Section II. A) and double-layer short-pitched (presented in Section II.…”
