  • Stator for a rotating electrical machine
    Patent number: 12323003
    Abstract: A stator for a rotating electrical machine comprises a stator mass comprising teeth and notches between the teeth, each of the notches being, on the air gap side, completely closed, electrical conductors being housed in the notches, the electrical conductors forming a fractional winding, for which the ratio q defined by q=Ne/(2pm) is written as an irreducible fraction z/n, z and n being two non-zero integers, n being different from 1, wherein Ne is the number of stator notches, m the number of winding phases and p the number of pairs of stator poles.
    Type: Grant

  • Stator for a rotating electrical machine
    Patent number: 12062962
    Abstract: A stator for a rotating electrical machine comprises a stator mass comprising notches housing the electrical conductors, wherein at least one portion of the electrical conductors, if not the majority, are in the form of a U-shaped pin, and each electrical conductor comprises first and second legs respectively extending axially in first and second notches, each electrical conductor comprising several strands, the strands of the first leg of an electrical conductor being arranged in the first notch in a radially reverse order of the strands of the second leg of the same electrical conductor in the second notch.
