Abstract
Embodiments of the present disclosure provide a rotor, a motor, a powertrain, and a vehicle. The rotor includes wedges and pole shoes. The wedges fit the pole shoes through curved portions. The curved portions can effectively relieve stress concentration of joint portions, increase strength of the wedges and the pole shoes, and effectively increase effective winding space of slots in the rotor. In this way, power density of a motor in which the rotor is used is increased.
