“…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.…”

For three-phase induction machines supplied by sinusoidal current, it is usual to model the n-bar squirrel-cage by an equivalent two-phase circuit. For a multiphase induction machine which can be supplied with different harmonics of current, the reduced-order model of the rotor must be more carefully chosen in order to predict the pulsations of torque. The proposed analysis allows to avoid a wrong design with non-sinusoidal magnetomotive forces. An analytical approach is proposed and confirmed by Finite-Element modelling at first for a three-phase induction machine and secondly for a five-phase induction machine.

“…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].…”

“…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].…”

In contrast to the current trend to higher DC voltages in BEVs (400 V to 800 V), the new and innovative electrical drive system ISCAD (Intelligent Stator CAge Drive) is based on a voltage level of 48 V. ISCAD is being developed at the FEAAM GmbH in cooperation with the Universität der Bundeswehr in Munich. A reduction of more than 20 % of energy demand in a driving cycle is simulated in comparison to a reference vehicle.
