State-of-the-art electrical drives for electric vehicles (EV) run on a battery voltage above 60 V (HV). This paper presents an alternative approach for use in future EVs: The Intelligent Stator Cage Drive (ISCAD) - an extra-low voltage drive for highest performance at battery voltages below 60 V (LV). First of all, the novel drive components are introduced with references to previously published papers on more concept details. A highly parallel set-up is chosen for maximum current capability and extremely low resistances. The novel 60-phase induction machine is made of solid aluminum bars instead of copper windings in the stator and a common squirrel cage rotor. The MOSFET-based inverter individually supplies every single stator bar in order to shape an extraordinarily smooth air gap magnetic field.
