Abstract: This application describes examples of a rotor, a permanent magnet motor and a powertrain. In one example, in a first rotor assembly of a rotor structure, each first rotor lamination is provided with a plurality of first permanent magnet slot groups, and a first boss is disposed at one end that is of each first permanent magnet slot of the first permanent magnet slot group and that is close to an outer edge of the first rotor lamination. In a second rotor assembly of the rotor structure, each second rotor lamination is provided with a plurality of second permanent magnet slot groups, and a second boss is disposed at one end that is of each second permanent magnet slot of the second permanent magnet slot group and that is close to an outer edge of the second rotor lamination.
