Abstract
Six-phase permanent magnet-type electric machines are disclosed. The electric machine includes a stator and a rotor configured to operate as a first three-phase electric machine and a second three-phase electric machine. The first and second three-phase electric machines are coupled with each other via a fractional slot combination with concentrated windings such that a mechanical separation between the first and second three-phase electric machines is at least 60 mechanical degrees.
