Driving range evaluation of a multi-phase drive for low voltage high power electric vehicles

Reduced-Order Model of Rotor Cage in Multiphase Induction Machines: Application on the Prediction of Torque Pulsations

“…According to the Table A 3 in Appendix C, the 10 most important space harmonics (excited by the sequence "u = 1") regarding their amplitudes in the winding function are: v = 1, 5,7,11,13,17,19,23,35,37. An interaction between two of these harmonics is considered important regarding the amplitude of torque pulsation.…”

“…Thanks to the aforementioned advantages, multiphase induction machines are becoming attractive in several sectors especially aeronautics [15], naval [16], and automotive industries [17]. With these increasing demands on multiphase induction machines, the design rules and theories, classically developed for the case of three phases, must be reconsidered.…”

An Induction Machine with Wound Independently-Controlled Stator Coils

“…As already underlined in Section I, the topology of the WICSC machine exhibits the inherent ability of changing the number of poles and active phases during operation. Therefore, by properly adjusting the number of poles or/and phases at different operating speeds, optimum efficiency can be achieved over the entire torque-speed envelope [10].…”

48-V Traction Battery — More than a Matter of Cell Configuration

“…Many advantages arise due to the high number of phases at a low voltage supply. These result in an excellent efficiency of the overall system, particularly in partial-load operation [3]. A reduction of more than 20 % of energy demand in a driving cycle is simulated in comparison to a reference vehicle [4].…”

“…These result in an excellent efficiency of the overall system, particularly in partial-load operation [3]. A reduction of more than 20 % of energy demand in a driving cycle is simulated in comparison to a reference vehicle [4]. In addition to machine and power electronics, the wiring system [5] as well as the traction battery were redesigned with regard to new requirements.…”
